Many persons may hear about the drilling mud solids control. But conerning how to purify the drlling mud, not so many people know well about it. Here we would like to talking about the drilling mud 4 stages solids control and 5 stages purification.
First stage for solids control & purification
Shale shaker is widely known as a solids control equipments used in drilling projects. It is a very basic equipment that could separate the drilling cutting more than 250 microns by fine mesh screens. During this stage, actually, the solids control and purificaion happens at the same time. Just as its name implies, solids control is separate the solids from the fluids, while the drilling cutting and other large size impurities being separated, the drilling mud is purified.

GN brand decanter centrifuge is a separation equipments used in the drilling mud recycling system. In this period of time, we have sent many sets of this type centrifuge to USA, Latin America and other area of the wrold.
Decanter centrifuge always used in the large system like the mud recycling system matching the drilling rig for oil & gas, geothermal etc. It is used as the 4th stage equipment to treat the drilling mud feeded by a submersible pump from the desilter tank compartment. Under normal condition, the centrifuge could separate the solids particals with the size of 7 microns. If a high speed variable frequency centrifuge is taken into application, even partical with size 2 microns could be removed out.
 drilling mud decanter centrifuge Here the problem come out. In the complete 4 stage treatment process, from shale shaker to mud cleaner (a combination of desander and desilter), then to decanter centrifuge, the solid particals separated from the mud is more and more smaller. So, customer often learn our centrifuge according to the partical size. It is a fact that the decanter centrifuge have a good performance in separating the tiny particals, but when it is working, the most important factor is the density of the particals and medium, rather than the partical size. And the density difference should be relative bigger. Once a customer who want to use this type centrifuge to separate microbes with size from 2 microns to 20 microns cultivated in water. As we can not confirm the density difference, we haven’t proposed our centrifuge at last. Continue reading »

In order to learn well about Trenchless Drilling Mud System, we have to know what is trenchless drilling technology. Trenchless technology is a type of subsurface construction work that requires few trenches or no continuous trenches. Because of the minimal disruption to surface traffic, business, and other activities, trenchless drilling technology is widely used in installation of new or replacement or rehabilitation of existing underground infrastructure.

Trip tank is a component of the auxiliary tank system for the drilling mud recycling system. It is shaped as a small metal tank which equiped with liquid-level gauge. Concerning the capacity of trip tank, we could find 2 statements: one is 10 to 15 barrels with 1-barrel divisions, and the other is 20-40 barrels with 1 bbl divisions. Whatever, it is a certain that the trip tank capacity is depended on the maximum well depth and the drill string size.
How Trip Tank Works
 Trip Tank Since the small volume, the mud surface height change is clear came to know when the mud flow rate changing. Therefore, trip tank is used to monitor the well. There are several operations that we can use the trip tank to monitor the well as follows;
1. When the drill string comes out of the hole, a volume of mud equal to that which the drill pipe occupied while in the hole must be pumped into the hole to replace the pipe.
2. When the drill string goes back in the hole, the drill pipe displaces a certain amount of mud, and a trip tank can be used again to keep track of this volume.

Have you ever heard multi shakers solids control unit/system? Or about the multi shakers-centrifuge solids control system? There was before, but nowadays, majority solids control unit for oil drilling ect. are not like that.
Presently, m0st solids control equipments are working under hard condition. The system doesn’t have strong ability to avoid ambient environment effect.
We know, drilling fluid solids control have developed very well during decade. This increase well drilling technique while decrease whole system repairing, ensure drilling fluid high property. Raise drilling speed, cut down cost, etc. So, all drilling people in oil and gas industry, mature solids control system is important mark for drilling
Shakers in solids control
Before 1970s, oil drilling solids control will use rather rude shale shaker. The separation particle size at least will be 440microns, solid will go into circulation again.
 Solids Control-Shakers Then there came up super fine shaker, hydrocyclone desander, desilter, centrifuge, degasser, agitator, mixing pump, etc. Also the mud tank, electric control panel. The solids can be limited as less than 5%. The density also can be adjusted as per actual demand
All of subsequent solids control equipments hould be based on shale shaker. Such as the treating capacity, the separation size, even whole mud tank, recycling system
Why we use multy shakers solids control unit?
In fact, complete solids control system will request rather high electric power input. Also the common shaker quantity won’t have sufficient treating capacity or flow rate. There was some company took 5 shale shakers used together.
These 5 shakers are adopting fine shaker screens. Then they won’t request desander, desilter. But use one set centrifuge. This save much power input give more simple structure, and higher reliability.

For oil well drilling rig, there should be many kinds of assistant parts when we do oil drilling project. Such as exploratory well, solids control, work over, completion, etc. Please find following detail on oil rig solids control
Oil rig drilling fluid solids control system is the insurance on high quality drilling mud. While qualified drilling fluid is ideal way to avoid any accident under well bore. High property drilling mud can avoid broken, protect drilling layer, increase drilling speed, cut down the drilling cost.
Oil rig solids control beginning
Actually, shale shaker, desadner, desilter in oil well drilling is from minning, and coal exploration industry. While centrifuge and degassers are from food and chemical industry. In long term, oil rig solids control can’t get specific development or get rid of former industry effect don’t have specific structure or features.
Howe
 Oil Rig Solids Control System ver, this is rather important for oil well drilling solids control.Since they have different processing medium. At the same time the things separated out and remain things are different we need to have different structure and feature.
Then, in later 1980s, we get some change or improvement on this situation. We have specialist on technique D&R team, especially, we have oilfield academe and university combined together for complete theory and design.
How China Oil rig solids control
At the beginning, Chine oil drilling company or oilfield services company adopt many degassers, shale shaker, desander, desilter, mud cleaner, mud agitator, centrifuges, centrifugal pump, etc. even complete drilling fluid solids control system/unit.
Meanwhile, this period also provide good opportunity for our oilfield technique swift development. Make China oilfield specialist grow better and better.Then, China oil rig solids control industry has a good start.
Oil rig solids control company list
In fact, solids control is a small part of oil well drilling. However, it is rather important for whole oilfield project. As we know, solids control have many functions. Including low down drill bit temperature, bring drilling cuttings out of well bore, lubricate drill pipe, etc.

GN solids control provide sales and service for the following :
Oil & Gas well drilling mud solids control system, equipment ,and spare parts.HDD & Underground mud recycling system ,equipment and spare parts, Industrial & mining, slurry separation system, equipment and spare parts.
 solids separation equipment Every day we received many inquiries from worldwide clients who are interested in solids separation equipments, quote and provide the most useful information to help client making a correct decision.
Listing some of their common questions .
1 If we provide part number and descriptions for popular brand equipments, if GN can make replacement one? For example, Mission Pump spare parts, Derrick hydrocyclone ( 4” cone and 10”cone), spring, rubber and shaker screen of Derrick Flo-Line shaker, Swaco Mongoose PT shaker spare parts, Brandt Cobra shaker spare parts, etc.
GN only produce our own brand equipments, so we can only provide spare parts for GN equipments, they can not replace for other brand equipment, even though they looked similar, they still have difference in structure.
2 If GN can produce similar shale shaker with other brand?
For example, Swaco Mongoose PT shaker, which has 2 kinds of vibrating motion , linear and balanced elliptical motion.
Can not at present, we have BEM shaker or Linear motion shaker, but can not combine them together in one machine. Maybe in the future, we will research new one to replace it.
For example, Dual deck shale shaker , which is combination of scalper(top deck) and bottom deck( fine screen), the benefit of 2 deck shale shaker is to increase the service life of bottom deck shaker screen, separate fine particles, to separate large solids(rocks) before entering into the real shaker.
Can not at present. We have tandem shale shaker which is combination of 2 sets of shale shaker, they are mounted in one skid, so it is convenient for transportation. Only a few clients need such top& bottom type 2 deck shaker, it is not popular trend in the market, so we did not have existing design. Commonly, even it is very large solids, you can still use GN shale shaker directly without any scalper.

General introduction of Geothermal well
Geothermal wells are wells which tap into the natural geothermal energy found beneath the Earth’s crust. There are a number of different types which can be utilized in various ways, ranging from wells which connect to sources of steam which can be used to power turbines to wells utilized in geothermal heat pumps, which maintain stable indoor temperatures with the use of a recirculating water system. Most of the world’s geothermal wells are found in areas of increased geological activity.
 Geothermal well drilling mud system Features of Geothermal well
Like other types of wells, geothermal wells are created by drilling into the Earth’s surface and then sinking in well rings to keep the hole from collapsing. Production wells are geothermal wells which connect to sources of geothermal energy, while injection wells are designed to force water underground for the purpose of maintaining a steady supply of water in the geothermal system.
Some geothermal drillers use AIR drilling for Geothermal but they will have to use drilling mud when we encounter water and the air won’t lift the water anymore. Then drillers will have requirement for mud recycling and solids control.
Geothermal well drilling mud system
Usually geothermal well drilling depth is not so deep as oil/gas drilling well, so they do not need very large treating capacity, but there is strict requirement to separate fine particles from the drilling mud, just like workover drilling rig mud system. For example, clients will need a decanter centrifuge in a workover mud system to keep the balance of the drilling mud.
Similar with oil/gas drilling mud solids control system, geothermal well drilling also need a vacuum degasser to process the invade mud. So usually you need to adopt the following equipments:
