Drilling fluid vibrating stirring equipment

Abstract

The invention provides drilling fluid vibrating stirring equipment. The drilling fluid vibrating stirring equipment comprises a screening box and a liquid collecting box arranged under the bottom of the screening box. The upper portion of an inner cavity of the screening box is of a cuboid structure, the lower portion of the inner cavity of the screening box is of a downward-protruding conical structure, and a material passing port is formed in the middle of the bottom of the screening box. A feeding port is formed in the position, corresponding to the material passing port, of a top plate of the liquid collecting box, the material passing port stretches into the feeding port, an elastic pad is arranged at the position, in contact with the outer surface of the bottom of the screening box, of the feeding port, inclined vibrating screens are arranged in a screening area, chip outlets are formed in the positions, corresponding to the lower ends of the vibrating screens, of the side wall of the screening box, a chip collecting box is arranged at the position, corresponding to the chip outlets, of the outer side wall of the screening box, a stirring device is fixedly arranged in the liquid collecting box, and a liquid outlet pipe connected with a liquid discharging slurry pump is formed in the side wall of the liquid collecting box. The drilling fluid vibrating stirring equipment has the advantages of being small in size, simple in structure, high in screening efficiency, good in screening effect, capable of effectively preventing drilling fluid from splashing and long in service life.

Description

technical field [0001] The invention belongs to the technical field of petroleum equipment, and in particular relates to a drilling fluid vibration stirring equipment. 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 drill...
