PREMISE CONDITIONS AND KEY PROBLEMS OF APPLIED STUDY OF INCLUSION IN OIL-GAS GEOLOGY

Tao Shizhen(Research Institute of Petroleum Exploration and Development of China, Beijing 100083)  
The paper expatiated on space time distributing rules and composition characteristics of inclusions in sedimentary rocks according to analysis of petrography, diagenesis and hydrogeology. The key problems were analyzed to apply study of inclusion in oil gas geology. The first problem was an autogenecity of inclusion. The diagenetic inclusion and successive one,diagenetic autogenetic mineral and clast grain from sedimentary rocks, cogenetic fluid and accidental fluid should be distinguished accurately under different circumstances. The second problem was multiperiodity of inclusion. It was necessary to recognize multiperiods of inclusions from same source and different source. Meanwhile, the essential standard to partition periods of inclusions was expounded. The third problem was distinguishment of inclusion re equilibrium and recovery of primal temperature. Finally, the important occurrences were pointed out in observation and experiment of inclusion, thus the research results of inclusion might accord with the geological facts.
