The pump efficiency and system efficiency of Zhongyuan
Oil-field are widely lower , workload of well-maintenance is
heavy. To settle this problem , we refer to the methods like
optimizing well-production parameters to improve system
efficiency in Jiangsu and Shengli Oilfield , and combine these
methods with system efficiency measure instances in our
Zhongyuan Oilfield , go along careful contrast and analysis , and
consider that with the continuous changing of working situation of
pumping wells these years , it is necessary to reduce the stroke
frequency of pumping wells reasonably ,further more ,we give out
a proposal method to reduce the frequency of stroke practically.
Our purpose is to improve the system efficiency of pumping
wells ,save energy costs ,prolong the use time of sucker rod and
tubing string and so on ,and increase our benefit ultimately.
