摘　　要：智能完井系统是一种实现井下流体闭环控制的技术,它能够在连续信息反馈闭环系统中进行监测、信息分析,并主动实施控制,完成几乎实时的操作。该技术可以根据储层特性进行分层生产调节控制,实现多层合采或分层开采,提高油气产量、加速生产,进行生产调节、开关层段无需停产或钢丝作业,减少相关生产作业费用和风险。智能完井技术的应用可以提高油气田的采收率和生产效率,降低生产成本和风险。目前,该技术已经在国内外的多个油气田得到了广泛应用,并取得了良好的效果。基于此,介绍了一种采用单管线液控滑套作为井下控制模块的方案来实现智能完井功能,在中海油海上油田得到成功运用,解决了井下大通径和开度可调的智能控制问题,使用效果良好。This article introduces the intelligent completions,a technology that realizes closed-loop control of downhole fluids,which is capable of monitoring,analyzing information,and proactively implementing control in a continuous information-feedback closed-loop system to accomplish almost real-time operations.The technology can be used to regulate and control separated layer oil production according to reservoir characteristics,realizing multilayer oil exploitation or separated layer oil exploitation,increasing oil and gas production,accelerating production,regulating production,and switching layers without shutting down production and wire-line work,reducing the related production and operation costs and risks.At present,this technology has been widely used in a number of oil and gas fields at home and abroad,and has achieved good results.This article proposes a scheme of using single tubing hydraulic control sliding sleeve as a downhole control module to realize the function of intelligent completion,which has been successfully applied in CNOOC offshore oilfields,solving the problem of intelligent control of downhole large diameter and adjustable opening,and the use of the effect is good.
