激发极化电位(IPR)测井技术的应用

Induced polarization potential (IPR) logging technique

油田开发至中后期 ,油层普遍存在水淹情况 ,导致电性、物性、含油性等变化 ,给测井及解释工作带来很大困难。通过IPR解释水淹层模型和方法的建立及应用 ,比较准确地解释了辽河油田储层的水淹情况 ,寻找区块剩余油分布规律 ,一定程度上解决了油层水淹问题 。

Watered-out is commonly seen in mid-late period of oilfield development, resulting in the change of electrical, petrophysical and oil-bearing property and bringing difficulty to logging and interpretation work. The establishment and application of IPR model for watered-out reservoir has given an accurate interpretation to the watered-out situation in Liaohe oilfield, and provides technical guarantee to stable production of the old oilfield.
