摘　　要：青西油田窿6区块油藏属深层裂缝型油藏。由于裂缝的规模、开裂度、分布以及连通性很不均匀,从而产生不同程度的水窜现象。当油井投产以后,首先是裂缝中的油被率先采出,使裂缝中的地层压力迅速降低,在裂缝中形成一个低能带,于是地层水沿裂缝快速窜至井底,从而形成油井出水。裂缝发育程度及其与水体连通程度决定了出水时间的早晚和出水量的大小。通过Logistic函数、Gompertz函数两种S型增长曲线预测模型,对窿6区块含水率进行拟合和预测。Qingxi oilfield Long6 block belongs to deep zone fractured reservoir.The scale,the opening degree,distribution and connectivity of the fractures are uneven,which lead to varying degrees of water breakthrough.The oil in the fractures is withdrawn firstly when the well is put into production.The formation pressure decreases rapidly in the fracture,forming a low energy zone in the fractures,so that the formation water will quickly break along the fractures to the bottom of the well,resulting in making the well produce water.The development of the fractures and their connectivity with the aquifer determine the water yield and the time when water break through.Conducted the water cut history matching and prediction of Long6 block by using Logistic function and Gompertz function these two kinds of S-shaped growth curve model,it provides basis for the next step developing measurement adjustment.
