胜利油田智能完井技术研究新进展

摘要

Intelligent well completion technology integrates sensing, information and control technology to increase well productivity,to lower operation risk and cost, to achieve effective use of resources, and to maximize oil field development.It is the development trend of modern well completion technology.This paper presents the state-of-art of intelligent well completion technology abroad and highlights the progress in Shengli Oilfield.Two kinds of external casing packers are developed.The overall performance of highstrength packer is close to the similar product abroad.The other is oil/water swell packer which satisfy the field requirements.Equi-flow screen segregated completion and data acquisition are developed.The mathematical model to analyze the downhole production and pressure was developed,which can be used to determine the water zone.This model is tested by segregated screen completion data acquisition experiment.The results indicate that it's reliable and can provide theoretical reference for segregated screen completion,and identification and controlling of water production.%智能完井技术综合运用传感技术、信息技术和控制技术来提高油井产能、降低作业风险和费用,实现资源利用和油田开发效益的最大化,是现代完井技术的发展方向.简单介绍了国内外智能完井技术的研究现状,重点介绍了胜利油田智能完井技术的研究进展情况:目前已研制出整体性能与国外同类产品接近的高强管外封隔器,能达到现场要求的遇油遇水自膨胀管外封隔器;形成了均衡供液筛管分段完井技术和数据采集技术;建立了处理井下产液和压力数据的数学模型,根据处理结果可以判断出水层位.通过筛管分段完井数据采集模拟试验,对采用数学模型处理井下产液和压力数据判断出水层位的方法进行了验证,结果表明,该方法可行,可为现场采用筛管分段完井及判断控制井下出水层位提供理论依据.
