AVO流体反演技术在川东北某区烃类检测中的应用

摘要

由于传统的AVO技术不能直观地评价储层的含油气性,提取的AVO属性与实际井的含气性符合程度不高,因此,在川东北某区进行含油气性预测时,引入了AVO流体反演技术对该区的含气性进行量化分析。此方法在川东北某区须家河组四段进行了应用,预测结果与实际钻井的含气情况相符合,并且在预测区域试钻获得工业气流,为该区的储层预测提供了有利的佐证。%As traditional AVO techniques can not be used to visually evaluate the hydrocarbon potential of the reservoir,so the extracted AVO attributes are not well in accord with the gas-bearing properties of the actual wells.This paper proposed AVO fluid inversion to analyze the gas-bearing properties in northeastern Sichuan.This technology was successfully applied in the fourth member of Xujiahe Formation in one area of northeastern Sichuan.The result was consistent with case of actual wells,and good results have been achieved,which affords a favorable evidence for reservoir prediction in this area.
