STUDY ON THE NUMERICAL SIMULATION OF PRODUCTION MECHANISM FOR THE TRIASSIC RESERVOIRS OF XIDALIYA OILFIELD, THE TARIM BASIN

According to the characteristics of the high water-content stage in which the development of Xidaliya oil and gas field is,the production mechanism of reservoirs is studied from production rate,vertical permeability,the distance from perforation to gas cap or to bottom water and the sensibility of penetration degree four respects,using reservoir numerical simulation softwares and based on single-well models.This provides theoretical bases for the further potential-tapping and recovery-raising of Xidaliya oil and gas field.
