针对雷家地区沙四段页岩油储层需要分级评价的问题,应用扫描电镜、氮气吸附、高压压汞等技术及储层分级评价方法,开展了页岩储层孔喉特征分析及分级评价研究.结果表明,雷家地区沙四段页岩油储层孔隙分为大孔、中孔、小孔三类,可将碳酸盐岩页岩油储层分为三个级别五种类型;结合水力流动单元划分,明确了雷家地区不同级别储层平面分布特征,其中,杜三层Ⅰ级储层厚度中心主要分布于中部,高升层Ⅰ级储层厚度中心分布于东北部.
Grading evaluation of shale oil reservoirs in the 4th member of Shahejie Formation in Leijia area of Liaohe Depression
Aiming at the grading evaluation of shale oil reservoirs in the fourth member of Shahejie Formation in Leijia area,by using scanning electron microscopy,nitrogen adsorption,high pressure mercury injection and reservoir classification evaluation methods,the pore throat characteristics and classification evaluation are analyzed.The results indicate that pores of the Sha 4 shale oil reservoirs in Leijia area can be divided into three categories:large pores,medium pores,and small pores.Carbonate shale oil reservoirs can be classified into three grades and five types.Combined with the division of hydraulic flow units,the planar distribution characteristics at different grades have been clarified.As for the grade Ⅰ reservoirs,the thick-ness center of Dusan layer is in the middle,of Gaosheng layer is in the northeast.
