塔里木盆地巴楚地区输导体系类型及油气成藏

从塔里木盆地巴楚地区输导体系类型入手,将其分成断裂、输导层和不整合面等3类.首先分析以上3类输导体系的形成及输导能力.在特定地质条件下,单一输导体系并不常见,从而提出以不同方式进行组合而形成的复合型输导体系,它是有效的油气运移通道网络.在不同地质时期,复合型输导体系类型及其对油气的运移能力是不断变化的.因此在同一含油气系统中,各种类型输导体系必须进行良好的时空配置才能对油气聚集起到促进作用.

PATHWAY SYSTEM TYPES AND HYDROCARBON ACCUMULATION IN BACHU AREA, THE TARIM BASIN

The pathway system is classified into 3 types of fault,carrier bed and unconformity in Bachu area,the Tarim Basin.First,it is analyzed the formation and migration ability of single pathway system.However,the single pathway system is not common under certain geologic condition,hence it is put forward the combination pathway system.It is an efficient hydrocarbon migration network.The classification and the migration ability of combination pathway system are changing.Consequently,only that the diversified types of pathway system are placed in their suitable locations temporally and spatially,can hydrocarbon accumulation be promoted.
