Strike-Slip Fault System in Kuqa Foreland Basin and Its Control on Hydrocarbon

Abstract

Abstract: In Tianshan orogen formed by collision between Tarim plate and Junggar plate shaped strike-slip fault system vertical and parallel to Tianshan orogen. The strike-slip fault system parallel to it is of an important effect on the formation and reformation of different structural zones in Kuqa foreland basin, while that of vertical to it gives rise to the structural segmentation in it. Strike-slip faults can form a series of related traps which provide sites for hydrocarbon accumulation. The arterial strike-slip faults have good sealing ability to stop hydrocarbon migration from one side to the others, while the derived strike-slip ones have good connectivity. Hence, the hydrocarbons in this basin could mainly accumulate in area with derived strike-slip faults; the arterial strike-slip faults allow the hydrocarbons to distribute by east-west segmentation and south-north zoning.

Key words: Kuqa foreland basin, strike-slip fault, structural segmentation, structural zonation, hydrocarbon accumulation
