Abstract

The invention discloses an electric drive type high-energy mixer for well cementation. The electric drive type high-energy mixer for well cementation comprises an ash valve main body, the bottom of the ash valve main body is provided with a mixer cavity through a connecting union, the side surface of the mixer cavity is fixedly connected with a water valve main body, a mixer cavity body is provided with a flange plate, the flange plate is positioned below the water valve main body, and the bottom of the mixer cavity is provided with a conical disc. The invention further discloses a mud premixing control method. The problems that in the prior art, a hydraulic drive type high-energy mixer is slow in response, poor in mud premixing effect and high in cost are solved.

Description

technical field [0001] The invention belongs to the technical field of oil field cementing equipment, and relates to an electric drive type high-energy mixer for well cementing, and also relates to a mud premixing control method. Background technique [0002] As the core equipment of oil field cementing construction, cementing truck (skid) has been widely used in cementing operation well sites, and cementing operations are usually carried out in the form of single or multiple 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 agitator in the mixing tank makes The mud is evenly mixed. At the same time, the circulating pump continuously pumps the mud in the m...
