Simulation Analysis Study on the Flow Field of Oil Well Pump Upstroke and Downstroke

During oil well production, it was a serious phenomenon of wax deposition on the parts such as oil production system section break. For the fluid flow problem of oil well pump upstroke and down stroke, the research of this thesis applies Flunt software to perform numerical simulation of the flow conditions under different outputs, and presents relevant velocity vector and velocity nephogram of the crude oil at oil well pump. Through analysis, it was believed that the wax deposition could not be efficiently settled only by high fluid velocity raised by output increase, and the relevant technical measures were proposed to prevent wax deposition, providing the theoretical thesis for paraffin removal and control at oil well.
