| 摘 要： | 苏里格气田盒8段是重要含气层位。本次研究充分利用钻井岩心、录井和测井资料,对该地区沉积相和砂体展布进行分析。研究认为该段从盆地北部由北向南依次发育辫状河沉积相和毯式浅水辫状河三角洲相,辫状河沉积相包括河道亚相和洪泛沉积两种亚相,毯式浅水辫状河三角洲相包括三角洲平原亚相、三角洲前缘亚相、前三角洲亚相。对盒8段砂体展布进行研究表明,在平面上顺物源方向呈现出条带状的分布特征,厚度变化差异较大,但平面上分布较为连续。

| Abstract: | He 8 is an important gas-bearing position of Sulige gas field. This study analyzed the sedimentary facies and sand distribution based on the core drilling, logging and logging data. It suggested that from north to south, the He8 member of the basin turned from braided river sedimentary facies to blanket shallow braided river delta, and to braided fluvial sedimentary facies include river and flood depositing two sub-phases, then to blanket shallow braided river delta, including delta plain, delta front, and pro-delta facies. The study of sand body distribution showed that the source direction along the plane of the distribution of the strip showed a change in the thickness of the differences, while the plane distribution was more continuous. |
