渤海油田分层注水井电缆永置智能测调关键技术
|
摘要
为了解决渤海油田常规分层注水中单井测调占用平台时间长、测调效率低,以及水平井和大斜度井适应性差等问题,研究了分层注水井电缆永置智能测调技术。将温度、压力、流量等测试单元集成于智能测调工作筒中,以电缆为传输电能和数据的介质,实现地面控制多口井、多层水嘴的连续开关,实时监测井下数据,形成了一套适用于海上油田的智能测调技术。38口井的应用实践表明,采用分层注水井电缆永置智能测调技术可大幅提高测调效率,缩短作业时间和减小作业空间,解决海上大斜度井、水平井测调难题。研究认为,该技术可为渤海油田经济、高效开发提供支持。
In order to solve the problems of excessive waste, low monitoring and adjusting efficiency, and poor adaptability in horizontal wells and highly deviated wells, which compete with conventional separate water injection techniques in the Bohai Oilfield, a cable implanted intelligent separate injection technology was studied. The test units of temperature, pressure and flowrate were integrated into the intelligent measuring/adjusting cylinder, and together with the cable, they were used as the power and data transmission medium. In doing so, they achieved remote control over multiple wells and multi-layer nozzles on the ground, and were able to establish the real-time monitoring of downhole data, thereby forming a set of intelligent monitoring and adjusting technologies suitable for offshore oilfields.The field practice of 38 wells showed that this technology could significantly improve the measurement and adjustment efficiency, save operation time and operation space, and address challenges in the measurement and adjustment of offshore highly deviated wells and horizontal wells. The study suggests that this technology can provide a technical basis for the economic and efficient development of the Bohai Oilfield.
