The Nm III group oil reservoir in Nanpu 2-3 area of Jidong oilfield is a newly developed conventional heavy oil reservoir with high oil viscosity,low water content in the initial production stage,and serious asynchronous phenomenon between the pumping machine and rod,resulting in well lying and pump inspection.This article analyzes the physical properties of crude oil,indicator diagrams,lifting techniques,and other data to optimize the lifting process and corresponding viscosity reduction measures for wells with different well inclinations.It solves the problem of asynchronous pumping machines and rods in heavy oil blocks and proposes measures to reduce costs and increase efficiency.
