Abstract

The invention discloses a centrifugal front-mounted degassing pump and degassing process flow experimental equipment. The centrifugal front-mounted degassing pump comprises a suction head, an exhaust pipe mounted on the suction head, and a front bearing bracket, a shell, a rear bearing bracket and a water pump connecting piece which are sequentially mounted below the suction head, a fluid inlet is formed in the front end of the suction head; a rotating hub head, a rotating hub, a rotating hub tail and a tail end rotating shaft are further sequentially installed in the shell. The degassing technological process experimental equipment comprises a pressure pump, and a dissolving tank, a funnel, an air compressor, a front degassing pump, a second vacuum pump, a centrifugal pump and a curing tank which are sequentially connected with the pressure pump; the front degassing pump is connected to the bottom of the dissolving tank; air enters the pipeline after being compressed by the air compressor, is mixed with the medicine powder at the funnel and carries the medicine powder to enter the dissolving tank; water is mixed with air carrying medicine powder in the dissolving tank after being pressurized by the pressure pump. According to the invention, secondary degassing is realized, and the stability is improved; after curing, a required mixed solution is obtained.

Description

technical field [0001] The invention belongs to the field of chemical flooding operations in oil fields, and in particular relates to a centrifugal pre-type degassing pump and experimental equipment for degassing process flow. Background technique [0002] As my country's demand for oil continues to increase, it is very important to further tap the potential of oil and gas fields. The chemical flooding technology is one of the more mature tertiary oil recovery technologies to enhance the oil recovery of the reservoir. However, during the chemical flooding injection process of the oilfield, there are bubbles in the polymer solution, which leads to the injection pressure deviation. Field problems such as high, polymer degradation, and underground pipe string corrosion arise. Therefore, it is necessary to perform a degassing process on the polymer solution to solve the above problems. [0003] At present, the conventional degassing methods mainly include gravity sedimentation...
