Physical foaming cement well cementation technology and matching system

Abstract

The invention belongs to a well cementation technology, particularly relates to a physical foaming cement well cementation technology and a supporting system. The system is characterized by comprising a stand, a liquid mixing pot fixed on the stand, air compressors, metering pumps, gas storage bottles, foaming pots, foam mixers, all-in-one joints and a foam outlet, wherein the stand is a cuboid structure, the U-shaped liquid mixing pot is fixed at the right end of the stand, and two U-shaped ends of the U-shaped liquid mixing pot are connected to the two sets of metering pumps respectively through pipelines; the U-shaped liquid mixing pot is respectively connected with two foaming pot pipelines through the two sets of metering pumps; a set of air compressors are connected with two sets of gas storage bottles, and the outlets of the two sets of gas storage bottles are also connected with the foaming pipelines through right safety valves and electromagnetic pressure regulation valves; the two foaming pots are connected to the two sets of all-in-one joints fixed at the left end of the stand through respectively connected foam mixers; and the two sets of all-in-one joints are simultaneously connected with the foam outlet. The invention provides the physical foaming cement well cementation technology and the supporting system, which can meet various requirements on the concentration and the pressure of the well cementation technology.

Description

technical field [0001] The invention belongs to well cementing technology, in particular to physical foam cement well cementing technology and a supporting system. Background technique [0002] In the cementing process, cement, fly ash, floating beads and other additive materials are mostly used in conventional cementing. On the one hand, the cost of well cementing is very high. On the other hand, there is a problem of low cementing quality, that is, the cementing is difficult to control. . Contents of the invention [0003] The purpose of the present invention is to provide a physical foam cement cementing technology and supporting system that can meet the various concentration and pressure requirements of the cementing process, have stable equipment operation and obvious cementing effect. [0004] The purpose of the present invention is achieved in this way, physical foam cement cementing technology and supporting system, it is characterized in that: it comprises frame,...
