中文摘要:
      玛湖凹陷斜坡区三叠系百口泉组属于致密砂砾岩储层,为讨论该套储层的孔隙结构类型及其与含油性的关系,利用铸体薄片、高压压汞、核磁共振、可视化水驱油等实验方法对研究区内岩石学特征、孔隙结构特征、渗流特征及含油性方面进行研究。结果表明:砂砾岩储层孔隙类型可分为剩余粒间孔、粒内溶孔、晶间孔及微裂缝;孔隙喉道类型主要为片状和点状吼道,以及管束状吼道等;综合两者关系由好到差将研究层段的孔隙结构划分为4类,随着孔隙结构的由好变差其含油性逐渐变差,渗流能力也对应变差。
英文摘要:
      The Triassic Baikouquan Formation in the slope area of the Mahu sag belongs to the tight glutenite reservoir. In order to discuss the pore structure type of the reservoir and its relationship with oil content in the study area, the characteristics of petrology, pore structure, seepage, and oil-bearing properties were studied by using the experimental methods of thin sections, high pressure mercury intrusion, nuclear magnetic resonance and visualized water flooding. The results show that the types of pore reservoirs in glutenite can be divided into residual intergranular, intragranular dissolved, intercrystalline pores and micro-cracks; the pore throat types are mainly sheet-like, point-like and bundle-like throats. The pore structure is divided into four categories. As pore structure tends worse, the oil content and the seepage capacity also gradually deteriorates.
