摘要
各大油田以注水为主要开发方式,很多油井发生水淹,油田进入高含水期,加之水驱过程使得储层发生不同程度的即时变化,给水淹层评价带来一定的困难。为了提高原油采出程度,必须对水淹层测井进行综合评价,准确地识别水淹层,以达到寻找剩余油富集区的目的。
Water flooding is the main development mode in each major oilfields,and many oil wells are flooded by water and the oilfields step into the high water cut period.Furthermore,the process of water flooding causes instant changes in reservoirs in different degrees,which brings some difficulties to the assessment of water flooded layers.In order to improve the degree of oil recovery,it is necessary to carry out a comprehensive assessment to the well logging of water flooded layer and precisely recognize the water flooded layer,and finally achieve the purpose of finding out the accumulation area of remaining oil.
