RESEARCH ON THE MIGRATION AND ACCUMULATION SYSTEMS OF NATURAL GAS AND HYDROCARBON MIGRATION OF THE LOWER CRETACEOUS STRATA IN KUQA DEPRESSION
库车坳陷下白垩统天然气运聚系统与油气运移研究

Based on gas potential distribution and evolution in geologically history periods, thinking of relation between with fluid dynamic and hydrocarbon migration accumulation. According of prineipia which hydrocarbon migration and accumulation systems is compartmentalized, nature gas migration and aceumu lation systems of lower Cretaceous period Jidike is compartmentalized and studied , nature gas accumulation is discussed, at the same time,according of the migration and accumulation systems and the distribution and evolution characteristic of lower potential area and center location which hydrocarbon is formed and development situation of fault, nature gas migration direction is analyzed synthetically.
