摘要
通过对塔西南野外露头区和盆地内主要含油层系的储集层特征研究及评价,认为塔西南储集层的岩石类型可分为碳酸盐岩和碎屑岩两大类,储集岩具有多种类型的孔隙,但以次生孔隙为主.成岩作用及成岩后生作用是控制本区储集层发育的主要因素.裂缝的存在对碳酸盐岩储集性能的改善起着决定性的作用.
According to the study on characteristics and evalution of outcrop and subsurface reservoir of major oil-bearing series in Southwestern Tarim basin, it is considered that reservoir rock of southwestern Tarim basin can be divided into two categories, i.e. carbonate and clastic rock. It has multiple types of pores in which secondary one is dominent. Diagenesis and epigenesis are major factors to control reservoir development. Fracture plays an important role to improve the reservoir property.
