Abstract

The invention discloses a sediment removal device for petroleum drilling fluid, and relates to the technical field of petroleum exploitation equipment. The device includes a sedimentation tank, one side of the sedimentation tank is provided with a circulation pipe, and the upper end of the circulation pipe is connected with the acceleration drive assembly; one end of the acceleration drive assembly is connected with a liquid inlet pipe, and the end of the liquid inlet pipe far away from the acceleration drive assembly passes through the centrifugal separation pipe Rotary joint connection. The device facilitates rapid separation of drilling fluid and sediment under the action of the rotation of the centrifugal separation pipe.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to a sand removal device for oil drilling fluid. Background technique [0002] Drilling fluid is the circulating flushing medium used in the hole during the drilling process. Drilling fluid is the "blood" of drilling, also known as drilling flushing fluid. The drilling fluid in the prior art is usually added with a variety of raw materials, such as positive gel, silicate, formate and polyols, etc., and its price is relatively high. High, the mud and sand in the drilling fluid are usually removed and then reused. [0003] When the traditional drilling fluid is recovered and treated, the combination of the sedimentation box and the filter box is usually used to filter the drilling fluid. However, this method of sediment removal takes a long time and has low work efficiency. It cannot quickly realize the separation of drilling fluid and sediment. separate. Conten...
