摘要/Abstract

摘要： 针对济阳坳陷沙河街组储层特征认识不深入,影响页岩油勘探与开发的问题,以济阳坳陷古近系沙河街组沙三下亚段和沙四上亚段重点取心井为研究对象,利用X-Ray Diffraction测定页岩储层矿物组分,通过扫描电镜对不同岩性页岩的储集空间和孔径进行定量刻画,分析页岩储层的优势岩性。研究结果表明:济阳坳陷页岩可划分为泥岩类、灰岩类、白云岩类,沙三下亚段泥岩类较为发育,沙四上亚段白云岩类较为发育;白云岩类发育中大孔,油迹主要赋存于白云石粒间微孔及溶蚀孔中;泥岩类发育中小孔,油迹主要充填于粒间微孔及粒间微缝中;灰岩类发育小孔,油迹主要赋存于晶间微孔中,局部赋存于溶蚀孔中;页岩储层的优势岩性依次为白云岩、泥岩、灰岩;不同岩性的含油率及试油数据表明,济阳坳陷沙河街组沙四上亚段属于高产油段,可作为济阳坳陷沙河街组“甜点”层系。研究成果对济阳坳陷页岩油勘探开发的深入具有指导意义。

Abstract: In view of the lack of deep understanding of the reservoir characteristics of the Shahejie Formation in the Jiyang Depression, it affects the exploration and development of shale oil. Taking key coring wells of the lower sub-section of the Member 3 and the upper sub-section of the Member 4 of the Paleogene Shahejie Formation of in the Jiyang Depression as the study object, X-Ray Diffraction was used to determine the mineral composition of shale reservoirs, and the shale was classified into mudstone Shale, limestone and dolomite, the mudstone in the lower sub-section of the Member 3 of the Shahejie Formation is relatively developed, and dolomite in the upper sub-section of the Member 4 of the Shahejie Formation is relatively developed; the reservoir space and pore size of shale with different lithologies were quantitatively described with the scanning electron microscopy, and the predominant lithology of shale reservoirs was analyzed. The results of the study show that the medium to large pores were developed in dolomite, and the oil are mainly occurred in the dolomite intergranular micropores and dissolved pores; the medium to small pores were developed in mudstone, and the oil were mainly filled in the intergranular micropores and intergranular micro-fractures; the small pores were developed in limestone, and the oil were mainly occurred in the intergranular micropores and locally in the dissolved pores; the dominant lithologies of shale reservoirs were, in order of preference: dolomite, mudstone and limestone; the oil content and oil test data of different lithologies showed that the upper sub-section of the Member 4 of Shahejie Formation in the Jiyang Depression is a high-production oil section, and it can be determined as the “sweet spot”reservoir of the Shahejie Formation in the Jiyang Depression. The study results have guidance significance to the exploration and development of shale oil in Jiyang Depression.
