摘要
依据螺杆泵开采重油的理论 ,结合泽 70断块稠油油藏的特点和原油物性 ,通过实施地层化学预处理、井筒降粘、螺杆泵井下锚定、螺杆泵优化设计、螺杆泵合理转速的确定、变频控制、井口换热降粘、螺杆泵监测等一系列螺杆泵配套工艺技术 ,使泽 70断块得以合理有效的开发。
According to the theory of developing viscous crude with screw pump and combined with the reservoir characteristic and oil property,Fault Block 70 is developed reasonably and effectively through a series of corollary technique including chemical pre processing in the formation,viscosity decrease in the well bore,down hole anchoring of screw pump,optimized design of screw pump,reasonable determination of the turning rate of screw pump,frequency alternating control,heat exchange and viscosity decrease in well head,monitoring of screw pump.
