1991年大庆油田实现了第16年持续稳产,年产原油5562.3×10~4t,是年产5000×10~4t以上稳产以来开发形势较好的一年。主要表现在以下三个方面。一是油田在继续保持注采平衡,地层压力稳定回升情况下,年注水比预计少注662×10~4m~3,年增长仅2.14％,是1985年以来增长幅度最小的。通过采取多种有效措施,高含水层位的注水量得到控 In 1991, Daqing Oilfield achieved its steady production in the 16th year with an annual output of 5562.3 × 10 ~ 4t crude oil, a good year since the annual output of 5000 × 10 ~ 4t stabilized production. Mainly in the following three aspects. First, while maintaining the balance between injection and production and the steady recovery of formation pressure, the annual injection volume of water injection will be 662 × 10 ~ 4m 3 less than expected, with an annual increase of only 2.14%, the smallest increase since 1985. By taking a variety of effective measures, the amount of water injected into the aquifer is controlled
