摘　　要：　通过对水淹级别进行研究，将油水相对渗透率资料进行处理，得到线性回归公式，求出水驱可动油饱和度和水驱剩余油饱和度。利用水驱特征曲线法和产量衰减曲线法，求出油田的可采储量；利用水驱最终采收率法求出油田的剩余可采储量；利用油井的产液剖面和注水井的吸水剖面分别求出小层的剩余油饱和度和剩余可采储量。以文南油田文136断块油藏为例，进行应用计算文136块沙二下油藏剩余可采储量及文136块沙二下油藏各小层剩余油化和度。ccording to the study of water flooded series,and dealing with the time of oil-water relativepermeability, we can obtain the fOrmula of linearregression and calculate the saturation of the movableand rernaining oil by water drive. Making use of thewater drive characteristics curve and the productiondecline curve to calculate the 0i1field's recoveraI)lcreserves. Using the ultimate waterfldri recoveryfactors Obtain the remainina recoverable reserves inthe field. Finally, the flllid producing profile andwater well injection profile can be used to calcu1atethe rernaining saturatlon and residual recoverablereserves in sublayers, Taking Wen l3 block inWennan oilfield as an example, we make use of abovementioned f0rmulas to calculate the remaining oilsaturation and the sublayers remaining oil saturationof the block.
