At present, hydraulic piston pump oil pumping process has been batch application. Downhole pressure measurement more difficult. In order to meet the analysis of oil well production and oil field development management requirements, hydraulic piston pump ,this paper proposes to use the calculation method to obtain the bottomhole pressure data, and introduces how to determine the accuracy of the related parameters calculation, and in order to improve the calculation formula.
From the list a few export pump suction pressure data visible, the measured and calculated
values of absolute errors, automated fuel management system the vast majority are + 0.2MPa or so, prove it is feasible and
reliable calculation method.
