大庆油田经历了复杂的开发历程:由初期的低速开发、中期的调整扩建产能高速开发、到高含水稳产开发、特高含水产量递减开发四个阶段;油田含水也经历了无水、低含水、中含水、高含水开发期。针对不断变化的介质环境和井况,机采采油技术也得到了不断的提高和完善,现主要有有杆泵采油、潜油电泵采油及螺杆泵采油三种方式。
Daqing Oilfield experienced a complex development process: from low-speed initial development, medium-term adjustment and expansion of high-speed production capacity development, development of high water and stable production, declining development of ultra-high water cut in four stages; oil field water has also experienced no water, low water, In the water, high water-cut development period. In view of the ever-changing media environment and well conditions, the technology of oil recovery and production has been continuously improved and improved. There are mainly three ways of sucker rod pump, submersible pump and screw pump.
