Sand remover for geothermal well drilling

Abstract

The invention provides a sand remover for geothermal well drilling. The sand remover for geothermal well drilling comprises a mounting bottom plate, a supporting mechanism, a sand remover body, a feeding mechanism, a sewage discharging mechanism, a discharging mechanism and a heat dissipation mechanism, wherein the top face of the mounting bottom plate is fixedly provided with the supporting mechanism, and the sand remover body is fixedly clamped and connected to the top of the supporting mechanism; one end of a feeding pipe is fixedly connected to a feeding pipe connecting base; a sewage discharging control valve is arranged on the sewage discharging pipe; the top of the sand remover body is fixedly connected with a discharging pipe; a water cooling cavity is formed between the wall of awater cooling radiator and the discharging pipe; the side, deviating from the sand remover body, of the discharging pipe and on the wall of the water cooling radiator is fixedly provided with a thermometer. The sand remover for geothermal well drilling has the advantages that the application range is wider, the drilling mud temperature can be reduced, a corresponding effect can be exerted in the using process, and slurry recycling is facilitated.

Description

technical field [0001] The invention relates to the technical field of geothermal drilling mud purification, in particular to a desander for geothermal drilling. Background technique [0002] Geothermal drilling refers to methods and devices for generating power from geothermal energy with a depth of about 3,500 meters or hot spring water with a water temperature greater than 30°C. It is generally divided into three categories: high temperature, medium temperature and low temperature. In the process of geothermal drilling, the role of drilling mud is very important, often used to clean the bottom of the drill cuttings, balance the fluid pressure of the formation, and lubricate and cool the drill bit and drilling tools. Therefore, in the drilling process, drilling mud is widely used as a very important resource, so some desanders for geothermal drilling are usually used to act on the mud to improve its quality. [0003] However, the current traditional desander used for geot...

Problems solved by technology

[0003] However, the current traditional desander used for geothermal drilling generally has a high temperature of the drilling mud, which is not conducive to the above-mentioned functions of the mud in the process of geothermal drilling, and is also not conducive to the recycling and reuse of the mud.
