| [摘 要]英买力凝析气田群区层组划分与对比研究是该地区陆相地层油气藏地质和开发工程中最基本和最重要的精细地质研究内容之一，也是急需解决的关键技术难题之一。本次研究采取“取心标准井出发，岩心标定测井，寻找辅助标志层，进行旋回对比、分级控制，将隔夹层纳入到同一沉积旋回进行识别、划分对比，以隔层确定小层，并兼顾‘就近、闭合’的原则”展开层组划分与对比，重新确定出更适用于气田开发的气层组、砂层组、小层等划分单元。而对可以作为层组划分与对比辅助手段的白垩系与古近系不整合界面、库姆格列木群底砂岩段顶界以及层组中的隔夹层等的识别，为层组的精细划分对比提供了重要保证，很好的解决了巴什基奇克组、库姆格列木群的层组划分问题，对英买力地区凝析气藏的后期开发等问题具有积极的指导意义。 |

| Abstract: Stratigraphic division and comparison of the Yingmaili condensate gas reservoir is a basic and important issue for terrestrial formation reservoir geology and development engineering, and is also a key technical problem to be resolved. This paper follows the principle of “Start from standard coring wells, use cores to demarcate well logging, find auxiliary marker beds to do cycle comparison, control level by level, make division and comparison of interbeds in the identical cycle of sedimentation, determine sublayers by interbeds, and compromise the near and close ”. We redetermine the gas bearing formations, sand bodies and sub-layers which are suitable for gas field development. And we identify the unconformities between the Cretaceous and the Paleogene, the top boundary of the bottom sandstone in the Kumugeliemu Group and interbeds used to be supplementary means of stratigraphic division and comparison. This resolves well the problem of stragigraphic division and correlation of the Bashijiqike Formation-Kumugeliemu Group, which provides guidance for the late development of the Yingmaili condensate gas reservoir. |
