Cementing equipment with mutually standby hydraulic systems

Abstract

The invention discloses cementing equipment with mutually standby hydraulic systems. The cementing equipment comprises a loading system, a hydraulic system connected with the loading system and a power system for driving the hydraulic system. The hydraulic system at least comprises a hydraulic pump, a switching device and an overflow valve, the hydraulic system is connected with a mixing system, and the hydraulic system is connected with a slurry mixing system provided with an AMS automatic slurry mixing system, a centrifugal pump circulating and filling system; the slurry mixing system is controlled and adjusted through a control system, the control system is arranged on a computer control platform, and the control platform is arranged on the loading system; and the loading system is based on one or more of a vehicle-mounted chassis or a trailer chassis or a skid-mounted chassis, wherein a semi-trailer based on the trailer chassis can be fixedly connected with a plurality of engines, a plurality of gear boxes, a plurality of plunger pumps, at least one metering tank, the slurry mixing system, a high-low pressure manifold, the control system, the hydraulic system and an electrical system.

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. [0003] The current...

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

[0003] The current conventional double-pump cementing equipment is diverse, such as 2 sets of power units + 2 plunger pumps + 2 clean water centrifugal pumps + 2 mud centrifugal pumps, the A-side engine hydraulic system drives 1 clean water centrifugal pump and 1 mud centrifugal pump, the engine hydraulic system on side B drives another clean water centrifugal pump and another mud centrifugal pump respectively; the hydraulic systems are not mutually backup, when the engine on side A is damaged, any centrifugal pump on side B will When damaged, the equipment cannot work; similarly, when the engine on side B is damaged and any one of the centrifugal pumps on side A is damaged, the equipment cannot work either
