摘要
应用大量的试井资料对百口泉油田百31井区二叠系油藏特征展开了深入分析,认为油藏具有均质和双孔两种渗流特征,主要以裂缝渗流为主,裂缝物性在油藏平面上存在一定的差异。对压力恢复曲线晚期段出现的下掉,认为是邻井干扰的结果,代表了整个油田区域的压力下降状况。利用干扰试井资料对生产井间的干扰影响程度进行的分析表明,该油藏是一个渗透性高、裂缝连通性好的高渗透裂缝系统的油藏。
The in-depth analysis is made for the Permian reservoir of Bai-31 Well Block in Baikouquan oilfield, Junggar basin, by using lots of well testing data. The result shows that the reservoir is characterized by homogenous dual porosity, dominated by fracture flow with certain differences in fractural petrophysical property in plane. The post section of buildup curves is in decline due to disturbance from offset wells, which represent the pressure decline status in the whole oil region. The analysis of the disturbance between production wells by using interference test shows that the reservoir is of characteristics of high permeability, good fractural connectivity and high permeable and fractured system.
