摘要
水驱特征曲线法是预测油田采收率和可采储量的常用方法,采用多种水驱特征曲线法计算石油可采储量,不同方法之间结果相差很大。绘制含水率与利用甲型、乙型、丙型和丁型水驱特征曲线法预测的可采储量采出程度的关系曲线,并与相对应类型的水驱特征曲线的含水上升规律特征模板进行拟合,选择拟合精度最高的预测结果,作为水驱特征曲线法的最终结果。通过在宁海油田、濮城油田沙一段和大庆油田南二三区葡Ⅰ组的应用,证明该方法效果较好,且简单易操作。
Water drive type curve method is a common method to predict recovery factor and recoverable reserves.The recoverable reserves calculated from various water drive type curves are significantly different from each other.The curves of water cut vs.recovery percent of recoverable reserves predicted by A,B,C and D water drive type curves are mapped,which is further matched with the water cut rising charts corresponding to each water drive type curves.The result with the highest matching precision is chosen as the final result of the water drive type curve method.The actual applications of the method in Ninghai oilfield,Sha-1member of Pucheng oilfield and Pu I formation in District Nan-2and Nan-3prove that good effects can be gained by using the simple and easy method.
