摘要
海拉尔盆地南屯组地质成因复杂,区域上储层特征差异大;由于储层岩石类型多样、孔隙结构复杂等因素导致测井识别流体精度较低。从储层特征分析入手,通过开展储层孔隙结构、岩石成分、电阻率侵入特征等方面的研究,确定了影响各区块流体识别的主要影响因素;以此为基础,综合应用岩心分析、压汞及常规测井资料,建立了基于孔隙结构特征、岩性变化和电性侵入特征的流体识别方法。经36口井试油验证,流体识别精度由75%提高到87.1%,取得了很好的应用效果。
The geological genesis is complex, in different regions the reservoir characteristics are large difference in Nantun formation of Hailer basin. Various kinds of rock and complex pore configuration lead to lower accuracy of fluid identification. Based on the analysis of reservoir characteristics, the main reasons which result in lower accuracy of fluid identification are determined by researching pore configuration, lithology element and resistivity invasion features. Then the fluid identification methods are established by using core analysis, Mercury injection and conventional logging data, the methods are based on pore configuration characteristics, lithology variation resistivity invasion features. The fluid identification accuracy which is verified by test data of 36 wells is increased from 75% to 87.1%.
