Reserch on the Pump - off Technology for Low Productivity Wells

摘要

The research is based on the fact that during the development of Ansai Oilfield, many oil wells expose the feature of low permeability, low productivity, low pump efficiency and intermittent production. Formulations about pump-off time, productivity are derived. The oilfield experimentation has known that the optimized pump - off time can improve economic benefit and does not decrease oil well's productivity.
