| 摘 要： | 综合考虑流固耦合作用、动态造缝效应、变裂缝导流能力等因素,建立了新的疏松砂岩油藏脱砂压裂产能模型,进行了多因素影响的脱砂压裂产能优化。研究表明:在流固耦合作用下,近井眼及近裂缝壁面储层物性参数变化显著,远离井眼及人工裂缝后,储层物性参数变化幅度明显减小;动态造缝效应主要对近井眼中心10 m以内储层参数产生显著影响;定导流能力与变导流能力影响下的储层参数差异主要体现在裂缝周边;在多因素综合影响下,脱砂压裂增产倍数明显低于常规渗流模型计算结果,且缝长越短,各因素综合影响越显著。

| Abstract: | With comprehensive consideration of the factors,i.e.the fluid-solid coupling effect,the dynamic fracture creation effect and the variable fracture conductivity,a new model of deliverability analysis of screening out fracturing in unconsolidated sandstone reservoir is established,and the deliverability of screening out fracturing is optimized under the influence of multiple factors.Research demonstrates that the physical parameters of reservoir near the wellbore and fracture surface change dramatically under... |
