江汉油区低效井特点及提高开发效果技术对策

江汉油区经历40年的勘探开发，受资源条件限制，开发难度越来越大。随着开发时间的延续，低效生产井越来越多，从开井生产的670口井统计，低效井比例达到23．9％。研究从低效井的分类入手，重点剖析造成油井低效的原因，探讨提高低效井开发效果的技术对策，主要包括五个方面的对策，即：深化综合地质研究、及时注采配套完善、强化两个剖面和注采动态调整、优化措施提高单井产量、工艺配套和工作制度的优化，对进一步提高低效井开发效果具有一定的指导作用。

Characteristics of Low Efficient Wells and Technical Countermeasures to Improve Development Effects in Jianghan Oil Region

Under the restriction of resources and 40-year exploration and development,further exploitation in Jianghan Oil Region is more and more difficult.The ratio of low efficient wells reach approximate 23.9% according to the statistics of 670 producing wells,so the number of low efficient wells becomes more and more with the time of exploitation.This paper starts with the classification of low efficient wells,mainly an- alyzes the reasons for inefficiency in oil wells and discusses the technical countermeasures ...
