摘要
为开发适用于渤海某油田3"小井眼和大井斜的智能分采工艺,以解决层间矛盾突出、措施增油效果不明显等问题,以实现油田持续增产稳产。研究方法采用理论计算、试验分析等,对电泵机组结构、电控配产器等进行优化设计,并创新研制系列配套工具。研究结果表明,新工艺在某油田D42ST2井成功应用,产油大幅上升,含水显著下降,控水增油效果显著。该智能分采工艺可行且高效,具有良好经济效益和推广前景,能为渤海油田智能分采技术规模化应用提供有力支撑。
The research aims to develop an intelligent separate production technology suitable for 3"small-boreholes and high-deviation wells in an oilfield in the Bohai Sea.This is to address issues such as prominent inter-layer contradictions and ineffective oil-increment measures,and to achieve continuous stable production and oil-output increase in the oilfield.The research methods include theoretical calculations,experimental analyses,etc.Optimization designs are carried out on the structure of the electric pump unit and the electronically controlled production allocator.Additionally,a series of supporting tools are innovatively developed.The research results show that the new technology has been successfully applied in Well D42ST2 of the oilfield.There has been a significant increase in oil production and a remarkable decrease in water cut,demonstrating a significant effect of water control and oil increment.The conclusion is that this intelligent separate production technology is feasible and efficient,has good economic benefits and broad prospects for promotion,and can provide strong support for the large-scale application of intelligent separate production technology in the Bohai Sea oilfield.
