摘要

摘要: 以GRI孔隙度和含油饱和度测定、高压压汞分析和地球化学测试为基础，建立了页岩油有效赋存空间的研究方法，并探索了东营凹陷古近系泥页岩孔径分布特征、含油孔径下限以及可动油赋存的有利物性条件。孔隙度与孔径分布关系表明，东营凹陷古近系泥页岩的孔隙度与10 nm以下孔隙所占比例负相关，与10 nm以上孔隙所占比例正相关，10 nm以上孔径的孔隙则是较高孔隙度泥页岩孔隙的重要贡献者；含油饱和度与不同孔径孔隙所占比例关系表明，古近系泥页岩中的油主要赋存在10 nm以上孔径的孔隙中；OSI指数与孔隙度关系表明，孔隙度在6.5%以上，且在生油窗范围内的泥页岩，是可动页岩油的有利储层。

Abstract: A comprehensive research method to determine effective reservoir spaces of shale oil was formulated based on GRI shale porosity and oil saturation testing, high-pressure mercury injection and geochemical analysis. The pore size distribution, the smallest pore diameter limit for oil occurrence, and the porosity condition for recoverable oil from the Paleogene shale in the Dongying Depression were discussed. The relationship between porosity and pore size distribution showed that shale porosity is negatively correlated to the volume portion of pores smaller than 10 nm (diameter), while positively correlated to the volume of pores with diameter larger than 10 nm, and that the pores wider than 10 nm are the critical contributor to the reservoir space of high-porosity shale. Shale oil mainly exists in pores wider than 10 nm. The statistical relationship between OSI (Oil Saturation Index) and porosity showed that the shale with a porosity above 6.5% is favorable for the occurrence of recoverable oil.
