Optimization and Application of Directional Well Beam Pumping Unit Model

At present, more than 90% of the total number of directional wells in the newly put into operation block of Y Oilfield are directional wells. The wellbore structure of directional wells causes complex mechanical effects of the rod and column, making it difficult to accurately predict the hanging point load of the pumping unit. This leads to unreasonable selection of pumping units during the construction of the new area, low load utilization rate, high energy consumption, and high investment. In order to improve the scientific design of directional well beam pumping unit selection, this article takes into account the influence of well deviation on the load of the pumping unit, and applies analytical method to calculate the maximum and minimum axial load of the directional well pumping rod. A directional well pumping unit selection chart is drawn. The on-site application situation shows that the model designed using the directional well pumping unit selection chart has increased the load utilization rate by 17.6% compared to the previous design models, Make the design of Y oilfield pumping unit models more reasonable and scientific.
