流体包裹体在鄂尔多斯盆地上古生界致密砂岩气研究中的应用

The Application of Fluid Inclusions to Tight Sandstone Reservoirs of Upper Paleozoic in Ordos Basin

包裹体技术在石油地质领域主要应用于确定古地温、成岩阶段、成藏期次和时间。本文总结了鄂尔多斯盆地上古生界致密砂岩气藏中流体包裹体在储层成岩阶段、成岩时间、成岩环境、天然气运移、天然气充注时间及期次、天然气成藏时间及期次和气藏后期改造等地质方面的应用,指出目前流体包裹体均一温度的应用中存在着一些问题,例如测温数据的有效性、包裹体形成后的变化、成藏期与充注期判试等。

The fluid inclusion techniques in the field of petroleum geology are mainly used to determine paleogeotem- perature, diagenetic stage, accumulation period and time. This paper summarized the research advances and applica- tion of fluid inclusion in the aspects of determining diagenetic stage, diagenetic time, diagenetic environment, natu- ral gas migration, natural gas filling time, natural gas accumulation time in tight sandstone reservoirs of the upper paleozoic in the Ordos basin. It was pointed out that there were some problems in the application of homogenization temperature of fluid inclusions, such as the validity of temperature measured data, the change after the formation of the inclusions, the judgment of the reservoir and the filling period.
