摘要:
以准噶尔盆地博格达地区中二叠统芦草沟组为研究对象,综合运用岩石薄片、全岩X射线衍射、氮气吸附、核磁共振和扫描电镜等储层表征技术,开展了不同岩相储层的储集空间、孔隙结构及含油性研究。结果表明:芦草沟组具有典型的混积岩沉积特点,可划分出泥页岩、砂岩和碳酸盐岩3种岩相类型;泥页岩储层储集空间主要为粒间溶孔、晶间孔、有机质孔、纹层理缝、构造裂缝和生烃超压缝等,以纳米级孔隙为主;砂岩和碳酸盐岩储层储集空间以粒(晶)间孔、粒(晶)间溶孔、粒(晶)内溶孔为主,页岩油以游离态为主。芦三段砂岩、碳酸盐岩和芦四段纹层状页岩的页岩油可动性好,为有利勘探类型。奇台庄地区和窝堡凹陷中北部地区为页岩油有利勘探区。
Abstract:
Taking the Lucaogou Formation of Middle Permian in Bogda area, Junggar Basin, as the research object, the reservoir characterization technologies such as rock thin section, whole rock X-ray diffraction, nitrogen adsorption, nuclear magnetic resonance and scanning electron microscope are comprehensively applied to carry out the research on reservoir space, pore structure and oil-bearing property of different lithofacies reservoirs. The results show that the Lucaogou Formation has the typical sedimentary characteristics of mixed rocks, which can be divided into three types: shale lithofacies, sandstone lithofacies and carbonate lithofacies. The shale lithofacies reservoir space mainly includes intergranular dissolved pores, intergranular pores, organic matter pores, striated bedding fractures, structural fractures and hydrocarbon generation overpressure fractures, etc., which are mainly nano-sized pores. Sandstone lithofacies and carbonate lithofacies reservoirs mainly have intergranular(intercrystalline) pores, intergranular(intercrystalline) dissolved pores, intergranular(intercrystalline) dissolved pores, etc. Shale oil mainly exists in free state. Sandstone, carbonate facies of the third Member of Lucaogou Formation and shale oil of the fourth Member of Lucaogou Formation are of good mobility. They are important shale oil exploration target types in the study area. Qitaizhuang area and the middle and north parts of Chaiwopu Depression are favorable shale oil reservoir development areas.
