摘　　要： 永乐油田储层地质情况复杂,水淹后测井曲线的水淹特征不明显,水淹层解释比较困难,目前尚没有一种通用的、有效的水淹层解释标准。针对油田储层实际特点,从岩石物理试验、水驱试验和相渗试验入手结合密闭取心资料以及加密调整井的生产数据,采用理论与实际相结合的方法,研究和总结了工区水淹特征和水淹规律,形成了定性识别和定量计算判别储层水淹级别的方法,确定了一套行之有效的计算产水率的方法,经油田试油和密闭取心资料验证,符合度高,适用性强,为油田后期的进一步开发和提高油气采收率提供了重要的解释方法。 In Yongle Oilfield,the reservoir geological conditions were complex,the characteristics of water-flooded reservoirs were not evident enough on the well-log curve after water flooding,the interpretation of water-flooded reservoirs was difficult,there were no universal and effective criteria for its interpretation.In allusion to the problems and based on rock physical property test,water flooding test and phase percolation test,pressure coring data and infilling well data,the method of theory was combined with production and a set of effective method of water-out characteristics and rules were summarized,by which a qualitative and quantitative discrimination method was established,a set of effective methods were determined for calculating water production ratio.It is demonstrated by pressure coring data,it is of high coincidence rate and high adaptability,it provides important way for enhancing oil recovery of the oilfield in the future.
