Mud ditch capable of cleaning rock debris conveniently

Abstract

The invention discloses a mud ditch capable of cleaning rock debris conveniently. The mud ditch capable of cleaning the rock debris conveniently comprises a ditch body and a board, wherein the board across the ditch body is erected at the upper end of the ditch body; a through hole and a circular ring-shaped groove are formed in the center of the board, the groove and the through hole are concentric, and the through hole is located inside the circular ring of the groove; the mud ditch further comprises a mixing bar penetrating through the through hole; a disc-shaped rotary table is sleeved with the mixing bar, and the rotary table is fixedly connected with the mixing bar; the upper surface and the lower surface of the rotary table are both perpendicular to the axis of the mixing bar; N rolling wheels are arranged on the lower surface of the rotary table, and the N rolling wheels are annularly and evenly distributed; the rotary table is located above the board, the N rolling wheels are all located in the groove, and N is an integer which is greater than or equal to 2; a plurality of rod-shaped protrudes are fixed to the surface of the mixing bar located below the board, and one ends, far away from the mixing bar, of the protrudes are in a pointed cone shape. By adoption of the mud ditch, the problem that in the prior art, blocking caused by stacking of the rock debris in a backflow ditch is inconvenient to clean is solved, and the purpose that the rock debris stacked in the backflow ditch can be conveniently cleaned is achieved.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a mud tank for conveniently processing accumulated cuttings. Background technique [0002] Mud tank, also known as drilling fluid tank and backflow tank, is a tank that passes between the wellhead and the solid control equipment when the drilling fluid flows back from the wellhead to the sedimentation tank or mud tank during the drilling and completion of oil production. It is used to convey the mud with cuttings or formation sand returned from the well. The mud tank is the sampling place for drilling fluid logging, which is of great significance for mud logging. Liquid level sensors are installed in the mud tanks to monitor the amount of drilling fluid returned, so that it is convenient for engineers to judge whether there is overflow, lost circulation or kick, etc. at the first time. Therefore, the liquid level signal measured by the liquid level sensor in the mud tank is of g...
