摘要: GOI(含油流体包裹体丰度指标)是流体包裹体丰富程度的一种指标,其大小决定于储层或圈闭内流体的充注程度;其值及属性变化可以反映出油气的充注历史。利用这一属性,对于一个研究区而言,进行系统的GOI取样和测定,可以确定出该区的油气运聚的平面和剖面最大范围。阐述了GOI的定义、确定油气运聚范围基本原理、判别标准及操作方法,在松辽盆地滨北地区的应用结果表明,滨北地区浅部储盖组合油气运聚范围平面上主要集中在靠近滨洲铁路线20000km2的范围内,剖面上主要集中分布在1500m~2000m的深度范围内。通过油气显示方法和源控油气藏分布规律方法进行验证,证明该方法行之有效。

Abstract: Index of Grains with Oil Inclusion indicates the richness of fluid inclusions in the rocks and its values and characteristics can be used to show the history of oil and gas migration and accumulation, which helps to delimit the most extension of oil and gas migration on the plan and the section in a area. In this paper, the definition of GOI has been introduced, and then the principle and the criterion as well as the operation process utilizing GOI delimiting the oil and gas migrating scope have been presented. The application on the Binbei area in Songliao basin showed that the oil and gas migration range of shallow accumulation assemblage in Binbei area mostly covered 20000km2 closed to the Binzhou railroad on the plan and the range of it mostly extends between 1500m and 2000m on the section. The oil and gas shows and the law of oil and gas distribution controlled by hydrocarbon source rocks confirmed the results.
