mud treatment in geothermal wells

The most prominent feature of geothermal well mud is its resistance to high temperature. High temperature will cause mud clay to disperse, thicken, and even solidify due to high temperature, which will damage the performance of the mud,Block the closed production layer and so on. Therefore, geothermal well mud treatment is a key problem in geothermal drilling. The mud treatment process of geothermal wells must be equipped with corresponding professional solid s control equipment . Characteristics of mud treatment in geothermal wells: 1) Blowout control: high-density mud is not suitable. 2) Mud treatment agent: Due to the high temperature of the geothermal well, the mud treatment agent should be guaranteed to be above 150C to maintain stable mud performance. 3) Heavy metal preparations: it
