Geothermal well mud refers to the mud used for geothermal well drilling. The most prominent feature of geothermal well mud is high temperature resistance. High temperature will cause the mud clay to disperse, thicken, and even solidify due to high temperature, which will destroy the mud performance and cause the well wall to collapse. , wellbore overrun, diameter reduction, drill bit mud bag, plugging closed production layers, etc.Therefore,
the Hot Well Mud Solids Control System is a particularly critical problem in geothermal drilling. The geothermal well mud treatment process must be equipped with corresponding professional solid phase control equipment. The selection of geothermal well mud is mainly determined according to the specific temperature of the geothermal well.
Geothermal well mud has the following characteristics:
1) Control the blowout: it is not suitable to use high-density mud
2) Mud treatment agent: Due to the high temperature of the geothermal well, the mud treatment agent is guaranteed to be above 150°C to maintain stable mud performance.
3) Heavy metal preparations: It is strictly prohibited to use to prevent environmental pollution.
4) Fine solid phase particles: Ensure that the content of solid phase particles is the minimum value.
5) Mud treatment equipment: must be equipped with solid phase control equipment
GREEN can process the mud solid particles produced by different geothermal well temperatures. The equipment of the geothermal well mud solid control treatment system includes: mud shaker, cyclone desander, desilter, mud cleaner, centrifuge, sand Pumps, shear pumps, submerged slurry pumps, mud mixers, jet mixing devices, mud guns, grit chambers, purification tanks and other equipment, as well as integrated 120m3, 240m3 geothermal well mud solids control systems.The Hot Well Mud Solids Control System can effectively control the solid phase content in the mud, control the solid particles in the mud below 5 μm to 15 μm, and at the same time prolong the life of the mud pump and drilling rig, and improve the drilling speed.
