流体包裹体在油田断裂研究中的某些应用

Some Aoolication of Fluid Inclusions to Study of Fault Oilfield

流体包裹体是构造热事件的流体代表,并在断裂构造岩中得以大量保存,通过对油田断裂构造岩中的流体包裹体的研究,能直接或间接得到许多有关流体(油、气、水)性质、活动特点及断裂构造特征的信息。论述了流体包裹体应用于油田断裂研究的理论基础、流体包裹体的研究内容及流体包裹体在烃类运移研究、油气保存条件研究及断裂构造分析中的某些应用,并探讨了其中存在的问题及发展方向。

Fluid inclusions are the samples of thermal fluid in structure events and are preserved in a great quanlity within fault rocks. It can directly or indirectly get the fluid (oil, gas, water) properties, active features and fault constructing characteristics, through studying fluid inclusions. Theoretic basis of fluid inclusions applied to the study of basin-fault, the major research methods of fluid inclusions ,and the application of fluid inclusion in the research of oil-gas migration, in the research of oil-gas preservation, and in the analysis of fault structure are discussed. At last,some problems in the study of fluid inclusions are discussed.
