近十年来,从以气为主的油气藏中采出的石油在总采油量中所占比例明显增长。但是,由于油气藏中同时埋藏着两类不同物理性质和开采条件的矿产(石油和天然气),以及产层的非均性,这种油气藏的开采是十分困难的。 Over the past decade, the proportion of oil extracted from gas-dominated reservoirs has increased significantly in the total oil production. However, the exploitation of such reservoirs is very difficult due to the two types of minerals (oil and gas) buried in the reservoir at the same time which have different physical and mining conditions, as well as the heterogeneity of the pay zone.
