摘要

伊通盆地莫里青断陷双阳组地层中发育有大量的水下扇砂体。大量的岩心观察、薄片鉴定、物性统计分析表明,水下扇储层属于中低孔、低渗—特低渗、细喉储层,储集空间类型以原生粒间孔隙和次生溶蚀孔隙为主,岩石类型以长石岩屑砂岩与岩屑长石砂岩为主,中扇储层物性好于外扇储层。根据区域储层评价结果预测有利储层,在平面上有利储层主要分布在靠山凹陷西南部以及尖山凸起东南部,这些地区水下扇砂体具有良好的油气勘探前景。

Abstract

A great of subaqueous fan sand bodies developed in Shuangyang Formation in Moliqing Fault Depression, Yitong Basin. Based on core observation, thin section analysis and physical property statistics, it is indicated that the subaqueous fan reservoir belongs to low-porosity, ultra-low permeability and thin throat reservoir. The reservoir space types are mainly primary intergranular pore and secondary erosion pore. The rock types are mainly feldspathic litharenite and lithic arkose. The physical property of middle fan reservoir is better than outer fan. According to the reservoir evaluation result, it is shown that the favorable reservoir mainly distributed in the southwest of Kaoshan Sag and in the northeast of Jianshan bulge. The subaqueous fan sand bodies in these areas have good potentials for oil and gas exploration.
