摘要:
吉木萨尔页岩油勘探开发采用高矿化度钻井液,居中型核磁共振测井快速评价页岩油储层品质难度大。以国产偏心型核磁共振测井资料、毛细管压力实验和补偿中子测井为基础,采用核磁共振总孔隙度与补偿中子孔隙度比值、核磁共振有效孔隙度、核磁共振T2几何平均值等建立吉木萨尔页岩油储层精细分类标准。研究表明:优质储层核磁共振有效孔隙度大; T2几何平均值、核磁共振总孔隙度与补偿中子孔隙度比值相对较高。研究形成了利用偏心型核磁共振测井快速评价吉木萨尔页岩油储层品质的新方法,为页岩储层的勘探开发提供了技术支持,技术推广性较高。
Abstract:
Due to the high salinity drilling fluid used in the Jimsar shale oil exploration and development, it is difficult to quickly evaluate the shale oil reservoir quality by centered nuclear magnetic resonance(NMR)logging. Based on eccentric NMR data, capillary pressure curve experiments and compensated neutron log, a fine classification standard of Jimsar shale oil reservoir has been established by using the ratio of NMR total porosity to compensated neutron porosity, NMR effective porosity, and NMR T2 geometric mean. The results show that high-quality reservoirs have large NMR effective porosity, T2 geometric mean value and NMR total porosity/neutron porosity value. Through the research, a new method using eccentric NMR logging to evaluate Jimsar shale oil reservoir quality has been formed, which provides technical support for exploration and development and has high technology promotion.
