The Research On Optimization Measures To Prevent The Eccentric Wear In Polymer-flooding Directional Wells

With the increasing difficulty of oil fields,more and more oil drilling projects in directional wells have been paid more attention to oil-fields in China and abroad.With the increase of the number of water-flooding diversion wells,the recovery rate has obviously improved,but at the same time,some new problems have emerged in the mechanical mining technology.By consulting a large number of domestic and foreign literature,it summarizes the domestic and foreign scholars for directional drilling sucker rod string contact analyzed.On this basis,the factors that cause eccentric wear of oil are analyzed thoroughly and meticulously,since Partial Wearing pumping wells it has become a constraint to improve the management level and affect the oil fields to achieve cost efficiency problems.The main reason is that pumping rod Force analysis of the column,oil wells caused by partial wear factors and partial wear prevention and control measures.To study the anti-eccentric wear working principle of the inclined well pump "Through the rod string,tubing and pumping oil pump complete optimization deviated rod pumping system optimization design goal",To achieve the desired effect of preventing the partial wear,inclined to meet production requirements,improved directional well rod pump production efficiency.
