Study of Applied Technology for Combination of Suck Rod and Jet Pumps

With the increasing of oil well and producing reserves, it is difficult for conventional artificial lift technology to meet the producing need. The article developed the combination of sucking rod and jet pumps in view of particular problem and particular needs. The paper tried to propose working theory of impulse jet pump, studied from context of system analysis, analyzed by the way of node analysis. According to harmonize relation between pressure and rate of flow, the paper made optimize design by use of multiple objective principle of optimality, and gave design procedure. It can satisfy production with deep well and ultra-deep well and shallow layer heavy oil, which improved the pump efficiency of suck rod and improving pumping behavior.
