Abstract

The invention discloses a mud premixing control method. A high-energy mixer is used, which includes an ash valve body, a mixer cavity is installed at the bottom of the ash valve body through a connection union, and a water valve body is fixed on the side of the mixer cavity. The body of the mixer cavity is equipped with a flange, the flange is located under the main body of the water valve, and the bottom of the mixer cavity is provided with a cone, which solves the problems of slow response and mud premixing effects of the hydraulically driven high-energy mixer in the prior art. poor and high cost.

Description

technical field [0001] The invention belongs to the technical field of oilfield cementing equipment, and relates to a mud premixing control method. Background technique [0002] As the core equipment for cementing construction in oilfields, cementing trucks (skids) have been widely used in well sites for cementing operations, and cementing operations are usually carried out in the form of single or combined construction. The high-energy mixer is the core component of the mud mixing system on the cementing vehicle (skid). The mud mixing system of the cementing truck (skid) is fully premixed by the clean water supplied by the water pump and the dry ash supplied by the ash tanker in the high-energy mixer, and then enters the mixing tank. The continuous stirring of the mixer in the mixing tank makes the The mud is evenly mixed, and at the same time, the circulating pump continuously extracts the mud in the mixing tank into the high-energy mixer for secondary mixing, which furth...
