摘要
运用基于标准井的水驱曲线类比法定性评价了水平段动用不均程度,在此基础上,利用渗流理论及动态数据,建立底水油藏水平井高含水期储量动用程度的计算方法,定量分析水平井高含水期储量动用程度,达到了定量评价层内干扰的目的,进一步利用数值模拟和过路井的水淹结果证实了方法的可靠性。计算了Q油田实际水平井的高含水期储量动用程度,指导了3口井的增产措施及1口调整井的设计方案,3 a来累计增油超过8.0×10~3m^3。该研究具有一定的矿场推广价值。
The producing level of lateral section is qualitatively evaluated by the waterflooding curve analogy of ref- erence well. Based on this evaluation, the seepage theory and production data are used to propose a producing level calculation method for the horizontal well in bottom-aquifer oil reservoir within high water-cut stage. The reserve producing level of horizontal well in high water-cut stage is quantitatively characterized to quantitatively evaluate the in-layer interference. In addition, this method is also verified by reservoir numerical simulation and cross-over well flooding data. The horizontal-well reserve producing levels within high water-cut stage in Q Oilfield is calcu- lated to provide guidance for the stimulation treatments of 3 wells and design plan of an adjustment well, and the corresponding cumulative oil increment exceeds 8.0× 103m3 in 3 years. This research can be promoted for field ap- plication.
