根据各种提高采收率方法的特点,结合油藏实际情况,有效地开展提高原油采收率的研究和应用,是我国油田发展的必然趋势。随着社会的发展,各国对石油的需求量与日俱增,以我国为例,1963年中国实现了石油自给,1993年开始进口石油,2000年进口量已达7200万吨。1990年,石油天然气在总能源消费中占18.7%,2000年上升到27.1%,提高了近9个百分点。随着对清洁能源需求的增加,这个比例还会不断攀升。因此,如何快速有效尽可能多地开发出地下
According to the characteristics of various oil recovery methods and the actual situation of oil reservoirs, it is an inevitable trend for the development of oilfield in our country to effectively study and apply oil recovery. With the development of society, the demand for petroleum in various countries has been increasing day by day. Taking China as an example, China achieved self-sufficiency in oil in 1963 and imported oil in 1993. Its import volume reached 72 million tons in 2000. In 1990, oil and natural gas accounted for 18.7% of the total energy consumption, rising to 27.1% in 2000, an increase of nearly 9 percentage points. With the increase in demand for clean energy, this ratio will continue to rise. Therefore, how to quickly and effectively develop underground as much as possible
