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.

Centrifuge is a widely used device in oil & gas drilling mud system. It always adopts decanter principle to separate suspension liquid. In the tank system, centrifuge is located as the fourth stage handling equipments to treat the drilling mud out from the mud cleaner.
MI-Swaco is really a world famous solids control specialist either in products quality or in service. Known to all the persons in solids control field, MI-Swaco’s equipments also have a higher price. Many customers inquiried us for the equivalent equipments of MI-Swaco, Derrick and some other famous brand.

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.

Why Need A Mud System in Trenchless Drilling
HDD is a well known type of trenchless drilling, in the drilling project, we will need the horizontal directional drilling rig. In order to protect the rig bit and make it easy for drilling, a good number of drilling mud will be used. Therefore, the need for mud system is emerged. During a large treating capacity trenchless drilling project, mud system is only partial unit of it. We can also find drill rig, mud pump and other equipments. Continue reading »

Shortly before, a client from Indonesia told us they plan to implement a pitless drilling system in their project for disposal the unused drilling mud.
What is Pit Less Drilling System
 500GPM Hydraulic Jack up solids control system Pit less drilling system is also call closed-loop drilling system. It employ a suite of solids control equipment to minimize drilling fluid dilution and provide the economic handling of the drilling wastes.
In the pit less drilling system where a reserve pit is not required, used drilling mud are recycled, and solid wastes can be landfarmed, hauled off or injected downhole.
Typcical Pitless Drilling System include:
1. Series of Linear motion shale shaker
2. Mud cleaner
3. Centrifuges followed with dewatering system: in the dewatering system, the High speed dencanter centrifuge and cutting drier are included.

Cleaning Tank is divided into 3 compartment,1# Shaker compartment,2# De-sander compartment,3# Mixing compartment.
1)Continues feeding of dirty slurry from mud pit to Shale Shaker. The 100YZ100-30 Submersible slurry pump feed slurry from mud pit to GNZS70-3 Shale Shaker at capacity of 615 GPM .Slurry pump is made from Cr26 Abrasion resistant
Alloy which allow users to pump high solids content fluids.
2)Pre-screening of the returned mud using GNZS70-3 Shale Shaker.This shaker can handle a throughput of more then 615 USgpm and is designed to remove particles down to 250 microns(60mesh), 7G force linear motion GNZS70-3 Shale Shaker with big screen area(2.6㎡) especially using frame pyramid screen treating capacity increased which allows user to use big mesh size for fine solids, and decrease the solids content and reduce solids load for Mud cleaner.
3)Secondary and third cleaning of the returned mud using a GNZJ70-3 (8″x2 + 4″ x8) Mud Cleaner.1# SB5×4-14 Centrifugal pump feed mud from 1# Shaker compartment to feed 8″x2 de-sander cones, where the particles larger than 50 microns are separated out by centrifugal force from desander cone nipple, and get down to GNZJ70-3 mud cleaner bottom shaker with a finer screen(150/200mesh) which again produces a virtually dry product. Major fluids with particle size less than 50microns goes to 2# De-sander compartment. This is the 2nd phase solids control.
2# SB5x4-14 Centrifugal pump suck mud from 2# desander compartment and feed to 4″x8 desilter cones. where the particles larger then 16 microns are separated out by centrifugal force from desilter cone nipple,and get down to GNZJ70-3 mud cleaner bottom shaker with a finer screen, which again produces a virtually dry product. Major fluids with particle size less then 16 microns goes to
3# Mixing compartment. This is the 3rd phase solids control.

Workover rig application
Workover rig is one kind of drilling rig also. It is widely used in oil and gas well drilling. Workover is used to refer to any kind of o & g well intervention involving invasive techniques, such as wireline, coiled tubing or snubbing. More specifically though, it will refer to the expensive process of pulling and replacing a completion
The workover begins by removing the wellhead and possibly the flow line then lifting the tubing hanger from the casing head and thus beginning to pull the completion out of the well.
 200HP Workover rig If the packer is retrievable it can be released easily enough and pulled out with the completion string. The string will almost always be fixed in place by at least one production packer.
Workover rig mainly including 200HP, 350HP, 450HP, 55oHP,650HP, 750HP.
200HP work over rig
Actually, 200HP work over rig is similar with 350HP work over rig. For 200HP work over rig we also need to treat it as common drilling rig. Their basic principle is almost same
To give 200HP workover rig better performance we also need drilling mud system to realise solids control or drilliing fluid reuse. We just got one inquiry from clients. They are doing oilfield service.
