Oil extraction mud purification device and purification method thereof

Abstract

The invention relates to the technical field of mud purification equipment, and discloses a mud purification device for oil exploitation, which includes a base, four sets of supports are fixedly connected to the four corners of the upper end of the base, and the upper ends of the supports are fixedly connected with fixing parts. The inner side of the fixed connection is fixedly connected with the screen box, the bottom of the screen box is fixedly installed with a screen, and one side of the middle part of the upper end of the base is fixedly connected with a first bracket. A servo motor is fixedly installed inside the connecting shaft on the left side. When the servo motor is not rotating, it is convenient for the auxiliary device to block liquid, prevent the mud from being lost without filtering, and spray water to clean the tail screen at the same time; when the servo motor can control the auxiliary device Rotate 90 degrees, at this time, the end with the brush is facing the screen, and the screen can be cleaned twice; when the servo motor rotates 180 degrees, the auxiliary device can remove the mud and particles on the surface of the screen, and at the same time Spray water to clean the screen.

Description

technical field [0001] The invention relates to the technical field of mud purification equipment, in particular to an oil exploitation mud purification device and a purification method thereof. Background technique [0002] In the process of oil drilling, the drilling fluid enters the bottom layer through the drill pipe, and after completing its function, it is discharged together with the waste generated in the drilling. Because the drilling fluid is not only expensive but also damages the environment, people will recycle the drilling fluid. Among them The petroleum mud vibrating screen is a commonly used oil mining mud screening and filtering device. Its main function is to filter the scattered materials with different particle sizes, so that the large particles remain on the upper part of the filter screen, and the small particles Can flow through the screen into the designated container.

Problems solved by technology

[0003] But the existing shale shaker still has the following deficiencies in the actual use process: First, although when the drilling mud reaches the screen set on the screen box, the solid-liquid two phases in the mud begin to separate, but the traditional shale shaker works When the solid particles and the liquid are not separated, they will leave the screen, especially when the amount of mud entering increases, not only the loss of drilling fluid will be caused, but also the environment will be polluted; secondly, when the existing shale shaker is working, Mud is easy to adhere to the surface of the screen, especially some vibrating screens with small mesh, which will not only block the mesh of the vibrating screen, affect the filtering effect, cause the drilling mud to be discharged without complete solid-liquid separation, and adhere to the surface of the screen The mud is difficult to clean up, making follow-up work difficult
