油气“倒灌”的物理模拟及其石油地质意义
Physical Simulation of Oil and Gas Backflow and Its Geological Significance
摘要
Abstract
The exploration practice proves that the phenomenon of the oil and gas backflow exists in Chezheng Depression, the physical simulation experiments of the oil and gas accumulation confirmed that there are two types of oil and gas intrusion in hydrocarbon migration process,i.e. fracture as migration channel and the sand body framework as migration channel,the former is the important channel of the oil and gas backflow,however molecular replacement is the formation mechanism,and the oil and gas pool is of small size. the latter in sand body framework for migration of oil and gas intrusion,is that pressure difference controlling petroleum downward migration is an important driving force. The desired maximum pressure depends on the related physical property of sandbody,and it can form large-scale oil and gas reservoirs. The research provides theoretical support for the expansion of deep oil and gas exploration in petroliferous basin.关键词
