含油气流体包裹体测试与应用问题综述

ANALYSIS,TESTING AND APPLICATION OF OIL-GAS-BEARING FLUID INCLUSIONS:A Review

在梳理含油气盆地流体包裹体测试常用技术以及流体包裹体在油气成藏研究中应用现状的基础上,结合塔里木盆地、准噶尔盆地、东海陆架盆地流体包裹体分析测试及应用研究经验,提出石英次生加大边中包裹体的可测性、均一温度测试对象的选取、后期演化对包裹体颜色分析的影响、肉眼鉴别包裹体荧光颜色的误差等包裹体分析测试时需注意的问题;提出包裹体GOI值受地应力场、储层非均质性等多重因素影响,在用于充注强度或古油藏研究时需谨慎;提出非连续埋藏型储层中包裹体均一温度数据的利用需要充分结合圈闭演化、输导体系演化、烃源岩生排烃演化等成藏条件演化,不宜简单利用均一温度厘定成藏期次.

With a review on the current situation of testing techniques and application for fluid inclusion from petroliferous basins in oil and gas accumulation study,combined with the research experience in Tarim Basin,Junggar Basin and East China Sea Shelf Basin,this paper discusses the measurability of inclusions in quartz secondary enlargement edge,the selection of homogenization temperature test objects,the influence of later evolution on inclusion color analysis,as well as the error of visual identification of inclusion fluorescence colors.Since the GOI value of inclusions is affected by multiple factors such as in-situ stress field and heterogeneity of reservoir,the method should be carefully used in the study of filling strength or paleo-reservoir.It is suggested that the utilization of inclusion homogenization temperature data in discontinuous buried reservoirs be fully combined with the evolution of reservoir forming conditions such as trap evolution,transport system evolution and hydrocarbon generation and expulsion evolution of source rocks.It is not propose to simply use homogenization temperature to determine the reservoir forming stages.
