抽油泵的排量系数是有杆泵抽油设备在油井中工作的重要技术经济指标,而抽油泵合理沉没度的选择则是在泵法开采中具有重要的实际意义。本文推导了抽油泵排量系数的理论计算公式,并在此基础上绘制了新系列游梁式抽油机—抽油泵装置所用抽油泵的排量系数和合理沉没度的选择图解,便于现场工人和技术人员使用时参考。
Displacement coefficient of sucker-rod pump is an important technical and economic index for sucker-rod pumping equipment working in oil well, and the choice of reasonable submergence of sucker-oil pump is of important practical significance in the pumping method. In this paper, the theoretical formula of pump displacement coefficient is deduced, and on the basis of this, the selection diagram of the displacement coefficient and reasonable submergence of pump in the new series of beam pumping unit - And technical staff reference.
