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 »

Mud Tank is widely used in the oilfield mud recycling system not only as the vessel of drilling mud, but also as the base of the drilling mud treatment equipments. In a complete mud recycling system for the oil well drilling rig, there would be many tanks involved. Sometimes, all these tanks looked same from out shape, and connected by pipeline; while other times, these tanks are various in demension and independent for different function. These tanks maybe given different names by different supplier, now, we will talk about the tank with name from GN Solids Control.

Mud Tank as Shaker Tank
From the shaker tank, we are getting into the mud cleaning system, in general condition, we will install shale shaker on the tank surface, and the quantity of shale shaker depends on the treating capacity of the system. In order to remove the gas from the drilling mud and enhance the efficiency of the following centrifugal pump which feed the mud to cyclone seperator, we could, as per the client requirment, install a vacuum degasser behind the shale shaker. If there is still enough space on the tank surface, we could install the desander, desilter or mud cleaner on it. However, we always install the mud cleaner in the next tank to prevent the crowded layout on tank surface, then we get into the next tank.

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:

Oilfield drilling Poor Boy degasser (mud gas separator) is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have a greater deviation not to meet the requirements of drilling. The serious situation is that would cause Chung well, and even blowout accident occurred, if not to treat it timely. ZYQ series Gas-liquid Separator combined with the (Company site: Solids Control System
Oilfield drilling Poor boy degasser that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.
