Description

technical field

[0001] The invention relates to the field of petroleum equipment, in particular to a cementing equipment in which hydraulic systems serve as backups for each other. Background technique

[0002] As cementing equipment is more and more widely used in well site operations at home and abroad, the concept of cementing operation quality, personnel safety, equipment safety and operation safety is becoming more and more prominent, and customers put forward stricter requirements for equipment quality and equipment reliability. . Conventional cementing equipment is generally designed through the principle of low-pressure manifold to realize mutual backup of centrifugal pumps. However, this method cannot realize the complete backup of the double-pump cementing equipment, so the general cementing operation requires two cementing equipment, one for use and the other for standby, the operation cost is relatively high, and human resources are wasted.
