Abstract

The invention provides a vibrating screen for petroleum drilling fluid, which includes a screening box, a liquid collection box arranged at the bottom of the screening box and connected with the screening box, and a bracket provided at the bottom of the liquid collection box; the upper part of the screening box is a Screening area, the lower part is the liquid passing area connected with the screening area, the screening area is a cuboid structure, and the liquid passing area is a downward convex conical structure; the liquid passing area is connected with the liquid collection tank; the screening area is equipped with an inclined The installed vibrating screen, the side wall of the screening box corresponding to the lower end of the vibrating screen is provided with a debris outlet, and the position corresponding to the side wall of the screening box and the debris outlet is provided with a debris collection box. A stirring device is fixed inside the tank, and a liquid outlet pipe connected to the liquid discharge mud pump is provided on the side wall of the liquid collection tank. The invention has the advantages of small volume, simple structure, high screening efficiency and good effect, and effectively prevents drilling fluid from splashing.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and in particular relates to a petroleum drilling fluid vibrating screen. Background technique [0002] Drilling fluid is an indispensable and important part of oil drilling operations. On the one hand, it is related to safe, fast and high-quality drilling, and on the other hand, it is related to the protection of oil and gas layers. The drilling fluid specifies a series of drilling fluid performance parameters according to the actual work needs. As the basis for adjusting and controlling the drilling fluid performance, the control of the solid phase content in the drilling fluid is one of them. Drilling fluid circulating from downhole to the surface contains a large amount of harmful solids such as cuttings, sand, etc., so it is necessary to remove harmful solids from the drilling fluid circulating to the surface. There are many methods for controlling the solids of petroleum drillin...
