摘要
综合运用数理统计分析,对DC区块砂岩油藏24口压裂井长6油层的地质参数和压裂施工参数等进行分析,筛选出压裂层渗透率、孔隙度、有效厚度、含油饱和度,压裂施工中的排量、破裂压力、工作压力、停泵压力、加砂量、砂比10个参数及其压裂有效临界范围,为DC区块以后压裂选井选层和优化设计提供了理论依据。
The reservoir and operation data of fractured well and fracturing treatment parameters obtained from 24 fractured wells in sand reservoirs of DC oilfield were analyzed by applying the statistical analysis method.Ten parameters were screened,including percolation rate,porosity,effective thickness,oil saturation,sand centration,delivery capacity,sand volumes,fracture pressure,operating pressure,shut-in pressure.Meanwhile, the critical range of these parameters for successful and effective fracturing are obtained, which are meaningful and important for the choosing layers and fracturing designing for oils in DC oilfiled.
