摘要(Abstract)：
硼 (钆 )-中子寿命测井以硼、钆化合物溶液作为指示剂 ,采用“测 渗 测”的方法 ,能够很好地解决多油层砂岩油田高含水后期监测储层剩余油饱和度的问题。该方法理论基础可靠 ,符合率较高 ,可操作性强 ,不受地层水矿化度、岩性和套管的影响。在油田高含水后期 ,能够准确确定高含水层位 ,检测窜槽层位 ,并能很好地反映不同储层及厚油层内部的剩余油分布情况 ,对增产、增注措施的选井、选层具有更强的针对性和准确性 ,有利于油田各项调整方案的优化与实施。
Boron(gadolinium neutron life time logging is a method for monitoring the residual oil saturation in late of high water cut stage of sandstone oil field. This paper introduces its theory and studies its application in determining high water cut horizon, seeking residual oil distribution, examining channeling horizon and comprehensive potential seeking of oil field. This method has a high percent of comformity and is easy to use. It cannot be effected by the salinity of formation water, lithology and casing. In the later stage of high water cut of oil field, it can accurately determine the high water cut horizon, examine channeling horizon and review the residual oil distribution of different reservoirs and thick reservoirs.
