辽河油田是一个开发建设40余年的老油田,油田开发已进入中后期。由于地层压力的降低,老井产量递减快,单井产量低。老井稳产已成为一个进入开发中后期油田是否长期稳产的重中之重,提高单井产量已跃然成为油田稳产和创效的“牛鼻子”工程。通过提高油井的泵效、延长油井检泵周期、合理控制生产压差、优化油井生产参数、详细制定油井工作制度是确保油井长期稳产的关键所在。
Liaohe Oilfield is a development and construction of more than 40 years of old oil fields, oilfield development has entered the late. Due to the decrease in formation pressure, the production of old wells decreases rapidly and the production of single wells is low. Old well steady production has become a middle and late development of the oil field is the most important long-term stable production, increase single-well production has become a field of oil production and efficiency of the “cow nose” project. By raising the pumping efficiency of the oil well, extending the inspection period of the oil well, controlling the production pressure reasonably and optimizing the production parameters of the oil well, it is the key to ensure the long-term stable production of the oil well by formulating the well working system in detail.
