摘要
为解决大庆油田注入井管柱堵塞,现有测调工艺无法兼容电控疏通装置所导致的施工停滞、测试效率低下等技术难题,研制一种新型电控疏通装置。依托创新设计理论、机械工程原理,融合电控可锚定技术与RS-485通信,设计“通—切—刮—定—控”多组件协同系统。该装置采用高强度碳锰钢材质,通过电缆传输信号与动力,确保与测调工艺兼容,适用于42~62 mm的管径。经大庆油田75口井应用,结果表明,装置疏通成功率达到93%,平均单次解卡作业时间从120 min缩短至30 min,井下锚定成功率为100%,年直接经济效益超过300万元。该装置提高了疏通效率和成功率,能与现有测调系统协同作业,对油田中后期高效开发提供技术支撑,具备的推广应用价值。
To address blocking issues in injection well tubing in the Daqing oilfield,where existing measurement and regulation processes are incompatible with electrically controlled unclogging devices,resulting in operational delays and low testing efficiency,a novel electronically controllable unblocking device was developed.Based on innovative design theory and mechanical engineering principles,the device integrates electronically controllable anchoring technology with RS-485 communication,forming a“cleaning-cutting-scraping-anchoring-controlling”multi-component collaborative system.Constructed from high-strength carbon-manganese steel and powered/signaled via cable,the device ensures compatibility with existing measurement and regulation processes and is applicable to tubing diameters ranging from 42 to 62 mm.Field applications across 75 wells in the Daqing Oilfield demonstrate a remarkable unblocking success rate of 93%,a reduction in average single sticking-release operation time from 120 minutes to 30 minutes,a 100%downhole anchoring success rate,and annual direct economic benefits exceeding 3 million RMB.This device significantly enhances unclogging efficiency and success rates and enables synergistic operation with existing measurement and regulation systems,providing crucial technical support for efficient field development in the later stages,and holding substantial potential for broad application.
