Abstract: Since Sucker-rod Pumping systems of many fields were designed through experience for a long time, most pumping wells often are in many problems, such as, pumping parameter design and hardware configuration irrationality, incongruity between pumping displacement and stratum in leakage capacity, low system efficiency, and low economic benefit. This paper mainly in-
troduced the research clue, function, characteristic, operating environment, and field application instances of the Sucker-rod Pumping system optimization design software, which can better solve the problems of pumping wells. Field application proved that the Sucker-rod Pumping system optimization design software can increase pumping system efficiency and producing capacity, and then obtain economic benefit and management level of oil field for pumping well.

Key words: pumping well, system efficiency, optimizing design, software, field application
