Himalayan orogeny is the main period of tectonic deformation and finalization of structures

as well as occurrence of abnormal high pressure and hydrocarbon accumulation in Kuqa foreland basin.Based on analysis of tectonic deformation and rock memory information

Himalayan movement in Kuqa foreland basin can be divided into three stages

corresponding to the end of Oligocene

the end of Pliocene and the end of early Pleistocene

with compressional intensity progressively strengthening and reaching peaks in late Himalayan.The neotectonics since middle Pleistocene mainly result in two or three uplifts

relatively weak folding and thrusting

and destruction of hydrocarbon accumulations in the area.Structural deformation in Kuqa foreland basin have been developed since early Himalayan

and the structural zones have successively been developed later and later southwards

which control the zonal distribution patterns of thrust folds

structural traps and oil and gas pools.The strong lateral compression in late Himalayan orogeny is the main factor leading to the abnormal high pressure

and the main controlling and driving forces for hydrocarbon migration and accumulation.Himalayan orogeny destroys and adjusts

to some extent

oil and gas reservoirs in the area.
