摘要
智能完井系统通过对井下产层流体参数的监测和控制,可以实现多层合采、层间优化、单采等多生产模式的任意切换。目前提供智能完井服务的公司都推出了以液压驱动为主要控制形式的井下流量阀控制系统,并在油田生产中成功应用。结合智能完井的技术要求,提出了一套井下流量控制液压系统的设计方案,可实现井下多目的层的分层选择和控制,利用3条控制管线,即可实现目前油田生产所需的2～6层的开发需要,可以减少安装过程中连接穿越管线的繁琐工作,为智能完井配套工具的标准化提供了支持。
By monitoring and controling of production layers,intelligent completion can achieve different production modes,includes separate production,multi-layer production,and optimization production.At present,all the intelligent completion service corporations provide flow valve system controlled mainly by hydraulic pressure,which is used successfully in field.According to the technology feature of intelligent completion,a new design method of downhole flow valve hydraulic control system is proposed,which can achieve control of multi-layer production,using 3 control hydraulic lines to control 2-6 layers,and relieve the excess work of installation of the complex hydraulic lines,and be in favor of standardized for intelligent completion related accessories tools.The design method proposed in this paper can be reference to the design and operation of downhole flow valve control system.
