低产井间歇抽油技术研究

本文根据安塞油田在开发过程，部分井表现出的低渗、低压、低产、低效与间歇出油的特征，推荐出低产油井间歇抽油的关井时间、开井时间及产量公式，并通过现场实践认识到，合理优化间开制度后，单井产量不会有较大程度的降低，且可提高低产井的经济效益。

A STUDY ON INTERVAL PUMPING TECHNIQUE IN STRIPPER WELL

During the course of exploitation practice in Ansai Oilfield,some oil wells have features of low permeability,low pressure,low production,low efficiency and interval oil flow.The formulations about shut-in well time,pumping time and production,for low productivity oil well with interval pumping are deduced.Through field experiment,the result shows that after optimizing interval pumping technique,output per well will not decrease,economic benefit of stripper well will be improved.
