The existing feasibility analysis method for gas injection in low permeability oilfields has the problem of poor rationality of injection and production parameters.In order to solve the above problems,a feasibility analysis method for gas injection in low permeability oilfield based on response surface method is proposed.The mechanism of gas injection in low permeability oilfields is analyzed.Based on the analysis results,the influencing factors of gas injection in low permeability oilfields are extracted.On the basis of extraction factors,the response surface method is used to construct the optimization model of injectionproduction parameters,optimize injection-production parameters,combine the optimized injectionproduction parameters with the influencing factors of gas injection in low permeability oilfields,calculate the feasibility parameters of gas injection in low permeability oilfields,and determine the gas injection in low permeability oilfields.Feasibility analysis of gas injection in low permeability oilfield based on response surface method is realized.Through the design of experimental equipment and the formulation of experimental steps,the experimental conclusion is that compared with the existing feasibility analysis methods for gas injection in low permeability oilfields,the proposed feasibility analysis method for gas injection in low permeability oilfields greatly improves the rationality of injection and production parameters,fully demonstrating that the proposed feasibility analysis method for gas injection in low permeability oilfields has better analysis performance.
