The technology for production profile logging in horizontal wells by artificial lift

  • 摘要: 随着油田开发向精细化方向推进,水平井占比的持续攀升与产液剖面监测技术滞后的矛盾日益凸显。国内现有机械采油水平井因缺乏专用测试通道及配套输送系统,导致生产动态监测数据严重缺失,直接影响油藏动态的精细把握与开发方案的优化调整。为此,研发出了适用于机采水平井的产液剖面测试集成化工艺:采用空心抽油泵实现地层流体举升与测试通道构建的双重功能,破解了地层产液和仪器输送同步实施的难题;开发了具有仪器输送和信号传输功能的刚性挺杆输送系统,确保测试仪器在水平段的高效精准输送和数据传输;设计了井下电缆对接装置,配合实现挺杆悬挂、推送及电缆对接功能。现场应用表明,该技术举升稳定,仪器输送成功率100%、测试数据合格率95.6%,成功定位出水层段的符合率达89.2%,较传统方法提升14.2个百分点。该技术的研发成功为油田高效开发与动态调整提供了关键技术支持。

     

    Abstract: As oilfield development advances toward refinement, the contradiction between the continuous rise in the proportion of horizontal wells and the lag in production profile monitoring technology has become increasingly prominent. At home, existing horizontal wells produced by artificial lift suffer from a severe lack of production dynamic monitoring data due to the absence of dedicated logging channels and supporting conveyance systems, directly affecting the precise understanding of reservoir dynamics and the optimization of development plans. To address this challenge, an integrated technology for production profile logging suitable for artificially lifted horizontal wells has been developed. A hollow sucker rod pump is employed to achieve the dual functions of lifting formation fluids and constructing a logging channel, solving the challenge of simultaneous fluid production and instrument conveyance. A rigid rod conveyance system with instrument delivery and signal transmission capabilities ensures efficient and precise instrument delivery and data transmission in the horizontal section. A downhole cable butting device is designed to assist in rod suspension, pushing, and cable butting. Field applications demonstrate that this technology ensures stable lifting, with a 100% instrument delivery, 95.6% qualified logging data, and 89.2% accuracy rate in locating water-producing zones, representing 14.2% improvement over traditional methods. The successful development of this technology provides critical support for efficient oilfield development and dynamic adjustments.
