Abstract

The invention discloses a working parameter configuration method and device for gas injection equipment, and belongs to the technical field of gas drive oil extraction. The method comprises the steps:acquiring target bottom hole flowing pressure based on various parameters of an oil well and a bottom hole flowing pressure calculation model; on this basis, based on a pressure difference calculation model of each wellbore section, obtaining the lower end pressure of each wellbore section in sequence, and finally obtaining the wellhead gas injection pressure of the oil well; based on the wellhead gas injection pressure, configuring working parameters of gas injection equipment; and injecting gas into the oil well. In the process, wellhead gas injection pressure is obtained based on preset bottom hole flow pressure and various parameters of an oil well. The method is simple, rapid and convenient, avoids the use of a gas injection compressor and related corollary equipment for testing, also avoids a complex implementation process, can quickly configure the working parameters of the gas injection equipment, improves the efficiency of the gas injection process, and also reduces the costof the gas injection process.

Description

technical field [0001] The invention relates to the technical field of gas flooding and oil production, in particular to a method and a device for configuring working parameters of gas injection equipment. Background technique [0002] Gas flooding oil recovery method is an oil recovery method commonly used in deep and low permeability reservoirs. In the process of using gas flooding method for oil recovery, it is necessary to configure the working parameters of the gas injection equipment so that the gas injection equipment can operate at a certain wellhead. The gas injection pressure injects gas into the oil well, so that the pressure of the oil reservoir reaches the production requirements for oil production. [0003] At present, the commonly used working parameter configuration method of gas injection equipment is to use the ground compressor for test injection to obtain the wellhead gas injection pressure and bottom hole gas injection pressure under different injection ...
