四川盆地大中型气田分布特点及勘探前景

DISTRIBUTION OF GIANT-MEDIUM GAS RESERVOIRS IN SICHUAN BASIN AND A FORECASTING ON GAS EXPLORATION

本文分析了四川盆地大中型气田分布特点,探讨了川东高陡构造区构造和气藏模式。从构造发育期与成烃期的配置、断裂发育特点、天然气圈闭资源量潜力及有利勘探区带评价等方面分析认为,该盆地将找到更多的大中型气田。

This paper analyzes the distribution of giant-medium gas fields in Sichuan basin,and gives a discussion on the tectonics and gas reservoir models of steep structural belt in east Sichuan province.After analyzing the relationship between development period in tectonics and hydrocarbon generation period, faulting characteristics,resources potential of gas traps and the evaluation for favorable exploration area etc.,it is suggested that more giant-medium gas fields will be found in the basin.
