摘　　要：塔河油田奥陶系油藏是典型的缝洞型油藏，复杂的地质因素导致了储层勘探开发难度大，生产规律不明显，含水变化复杂。提出3条新型的生产动态描述曲线，即累计产油量一累计产液量、累计产水量一累计产液量和油水累计差量一累计产液量曲线，曲线的斜率可以很好地反映油井的含水变化。根据曲线形态，将塔河4区的油井划分为缓慢见水型、暴性水淹型和间歇出水型等3种见水类型，并预测了缝洞储层体，分析了油水配置关系，建立了与出水类型相对应的3种缝洞储层模型。The Ordovician oil reservoir in Tahe Oilfield is a typical fractured-vuggy oil reservoir. Complex geolog- ical factors result in rather difficult exploration and development of the reservoir, not obvious production laws and complicated change of the water cut. three new-type production performance curves are presented： accummulative oil production-accummulative liquid production, accummulative water production-accummulative liquid production and the residual quantity between the oil and water accummulative productions-accummulative liquid production; the slopes of the curves can much better reflect the water changes of the oil wells. According to the shapes of the curves, three kinds of the water breakthrough such as slowly through, suddenly through and intermittently through forms are divided in the oil wells of Block 4 in Tahe Oilfield. At the same time, the fractured-vuggy reservoir bodies are predicted, the matched relations between the oil and water are analyzed, three types of fractured-vuggy reservoir models are established in accordance with the kinds of water breakthrough.
