国内外水平井智能控水技术研究进展

Research Progress of Intelligent Water Control Technology in Horizontal Wells

随着开发的延长,水平井开发高含水问题尤为凸显,稳油控水难度日趋加大。国内外学者聚焦水平井控水研究,提出多项筛管完井控水技术,笔者通过充分调研与对比,整理出浮片式智能分流装置、流速控制阀(RCP)控水技术、自动流入控制阀(EquiFlow)控水技术和"Y"型导流装置控水技术等,介绍装置结构及控水原理,为水平井智能控水技术的进一步研究提供方向。

High water cut in horizontal wells is becoming more and more remarkable with the production time goes on, which makes it be more difficult to decrease water cut and enhance oil recovery. Domestic and foreign scholars focused on the research of horizontal well water control, and proposed a number of screen completion water control technologies. Through thorough investigation and comparison, some water control technologies were discussed, such as floating-piece intelligent diversion device, flow rate control valve(RCP) water control technology, and automatic inflow control valve(EquiFlow) water control technology, "Y" type diversion device water control technology and so on. The device structure and water control principle were introduced, providing a proper direction for further research on horizontal well intelligent water control technology.
