Artificial Lift Improvements and Practice of Moderate Sand Production Well

  • Aiming at the problems that wells in the BZ oilfield frequently cause sandbore and sand plugging due to sand production, and the failure rate of the electric submersible pump is high, which restricts the high-speed and high-efficiency developments of the oilfield, this paper uses the theory of spherical sand sedimentation velocity to carry out the research on the minimum sand carrying capacity and guides the electric submersible pump. Selection and improvement of sand carrying capacity of wellbore through production string optimization. After the implementation of the technology, the fault wells showed a downward trend. The average pumping period of the sand wells was increased from 328 days to 735 days, and the failure rate of the sand well units was reduced from 21% to 11%.The sand trapping of the oil well caused by oil well status adjustment was buried to 0. The practice of the mine proves that through the optimization of the selection of the electric submersible pump, the production of pipe string structure is optimized, and the capacity of the wellbore carrying sand is effectively strengthened, the pump cycle is prolonged, and the oilfield development efficiency is improved.
