我国石油工业作为世界石油市场的一部分,经过十多年改革,实现了年产原油1.35亿吨,年产天然气150多亿立方米,每年出口原油2,000万吨左右,正以稳定增长的步伐跨入90年代。但是,目前大部分主力油田已进入稳产末期阶段。人国油田平均采出程度已占可采储最的50％以上,平均综合含水已达75％以上,实际综合递减率为7.15％。到90年代,油田维护及弥补递减工作量大幅度增加,生产费用上涨,综合经济效益下
As part of the world oil market, after more than 10 years of reform, China's oil industry has achieved 135 million tons of crude oil annually, and has an annual output of more than 15 billion cubic meters of natural gas and about 20 million tons of crude oil exported annually.
