低渗透油藏压裂水平井产能预测研究
Prediction of the Productivity of Multiple Transverse Fractured Horizontal Wells in Low Permeability Reservoirs
摘要
Abstract
The horizontal well productivity prediction method was analyzed in theory.However,the existing mathematical model and evaluation method does not consider the influence of start-up pressure gradient and the pressure-sensitive effect on fracturing horizontal well productivity,which is not reasonable in low permeability reservoirs.A method considering the effect of start-up pressure gradient and the pressure sensitive was provided in this paper.The results showed that the larger the start-up pressure gradient,the greater impact on the fracturing of the horizontal well productivity.Therefore,when the fracturing horizontal well productivity model was established in low permeability reservoir,the parameters of start-up pressure gradient must be considered.The larger integrated compression coefficient,the greater impact on fracturing horizontal well productivity. The greater the pressure drop,the influence on coefficient of the comprehensive capacity is larger.Therefore,when the elastic reservoir was exploited,a feasibility of optimization design of production pressure were needed.The best crack number was 4~5,and crack length was about 120 m.关键词
