辽河油田经过二十八年连续的高产稳产,已经步入油田开发中后期、产量快速递减阶段。随着国内外经济下行压力加剧,市场油价波动和业务发展不平衡等不确定因素增多,使辽河油田开采成本越来越高。曙光油田自上世纪70年代开发以来,可采储量采出程度已达到82.4%,自然递减率达到38%,稀油主力区块进入“双高”阶段,占总产量规模85%的稠油区块地层压力仅有开发初期的13%,开发程度在国内同类油气藏中接近极限。因此,如何降本节支提高效益成为油田各单位关注并深入研究的内容。
After twenty-eight consecutive years of high-yield and stable production, Liaohe Oilfield has stepped into the middle and late stages of oilfield development with a rapid decline in output. With the deepening downward pressure on the domestic and international economies, increasing uncertainties such as fluctuations in oil prices and unbalanced business development, the cost of mining Liaohe Oilfield is getting higher and higher. Since the development of Shuguang Oilfield in the 1970s, the recoverable reserves have reached 82.4% and the natural decline rate reached 38%. The major oil and thin blocks have entered the “double high” stage, accounting for 85% of the total output. The formation pressure in the oil block is only 13% at the initial stage of development, and the development level approaches the limit in the similar reservoirs in China. Therefore, how to reduce costs and improve efficiency has become the concern of oil field units and in-depth study of the content.
