Influence Factors and Screening Method of CO2Huff& Puff in Tight Oil Reservoir Based on Multi Index
摘要
Abstract
Based on the analytic hierarchy process,a multi index comprehensive evaluation function of CO2huff and puff is proposed in this paper.Orthogonal experimental design method and numerical simulation are adopted to ana-lyze the main controlling factors of CO2huff and puff in multilevel fractured horizontal well in tight reservoir.Ac-cording to the results,the most important factors of CO2huff and puff in tight reservoirs are oil saturation,natural fracture density,oil viscosity and reservoir thickness.Combined Box-Behnken experimental design method with numerical simulation,a surrogate model is established to calculate the new evaluation parameters of CO2huff and puff in tight oil reservoir.The established model can be used to predict and sort the oil well CO2huff and puff quickly according to the basic parameters of production well.关键词
