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.
