摘要
过套管电阻率测井是套后电测油层电阻率的新方法。通过与裸眼井电阻率对比,利用衰竭指数定性评价油层水淹程度。参考碳氧比测井资料,逐一砂体进行论证,综合分析砂体剩余油成因,认为该项新技术能够确定油层剩余油富集部位。萨北开发区采用此新方法测井3口,对方法的适用性有一定的认识。以该测井资料为指导,在聚驱后的北2丁-5-P17井上采取补孔措施挖潜,效果突出,认识到该项技术是高含水后期测试剩余油行之有效的方法之一,将在多学科油藏研究以及指导北三东CHFR试验区措施挖潜中发挥重要作用。
CHFR is one method for electrically measuring oil layer electric resistivity.With the comparison to open hole electric resistivity,depletion index is used to qualitatively evaluate the water flooded degree of oil layers.With the reference to carbon-oxygen ratio logging data,the sand body is discussed one by one.Based on the comprehensive analysis of the genesis of remaining oil in the sand body,it is believed that this new technique can be used to determine the remaining oil abundance parts in oil layers.This method has been applied in 3 wells in north Saertu area,and some understanding was obtained.According to the experience,reperforation measure has been applied in well B2-D5-P17 after polymer flooding.The application results are obvious.This method is one feasible and effective technique to test the remaining oil at the late period of high water cut stage,and it can play an important role in multidisciplinary oil reservoir research and the further development of CHFR experimental area in B3D.
