中国石油网消息：截至5月11日，青海油田井下工程技术公司张峰工作室攻关研发的 “井口螺栓安全拆装液压控制工具”已正式投入现场应用50余天。该工具将原本需要3个人协同完成的作业优化为单人独立操作，螺栓拆装时间由传统的3分钟缩短至1分钟，作业效率提升80%以上，通过标准化、机械化操作，进一步筑牢了本质安全防线。

China Oil News: As of May 11th, the "Hydraulic Control Tool for Safe Disassembly and Assembly of Wellhead Bolts" developed by Zhang Feng's studio of Qinghai Oilfield Downhole Engineering Technology Company has been officially put into field application for over 50 days. This tool optimizes the original operation that required three people to work together into a single-person independent operation. The time for bolt disassembly and assembly has been shortened from the traditional 3 minutes to 1 minute, increasing the operational efficiency by more than 80%. Through standardized and mechanized operations, the fundamental safety line has been further strengthened.

传统井口螺栓拆装作业长期依赖人工大锤敲击方式，不仅存在操作风险高、作业不规范等问题，还会出现工具断裂、飞溅等安全隐患，既影响作业效率，也增加了安全管理成本。

The traditional operation of disassembling and assembling the wellhead bolts has long relied on the manual hammering method. This approach not only has high operational risks and irregular work procedures, but also poses potential safety hazards such as tool breakage and splashing. It not only affects the efficiency of the operation but also increases the cost of safety management.

为破解难题，张峰工作室组建专项攻关小组，聚焦现场作业需求，经多次研讨、模拟测试和现场实操验证，成功研发出井口螺栓安全拆装液压控制工具。该工具运用稳定可靠的液压传动原理，核心部件经过特殊工艺处理，可适配井下作业15种不同规格的井口螺栓，实现螺栓拆装过程的精准、可控与平稳操作。

To solve the problem, Zhang Feng's studio established a special research team, focusing on the on-site operation requirements. After multiple discussions, simulation tests and on-site practical operations for verification, they successfully developed a hydraulic control tool for safe disassembly and assembly of wellhead bolts. This tool utilizes a stable and reliable hydraulic transmission principle. The core components have undergone special processing and can be adapted to 15 different specifications of wellhead bolts for downhole operations, enabling precise, controllable and smooth operation during the bolt disassembly and assembly process.

目前，该工具已在井下工程技术公司作业保障大队采油树维修车间全面推广应用。投入应用以来，累计完成螺栓拆装作业30余次，作业合格率100%，未发生一起安全隐患。

Currently, this tool has been fully promoted and applied in the oil well maintenance workshop of the Production Assurance Team of the Underground Engineering Technology Company. Since its application, it has completed more than 30 bolt disassembly and assembly operations, with a 100% operation qualification rate and no safety hazards have occurred.

下一步，井下工程技术公司将加快推动该项创新成果在各作业现场落地见效，计划在未来扩大应用覆盖面，实现所有井口作业岗位全覆盖，切实把技术优势转化为安全优势。

Next, the underground engineering technology company will accelerate the implementation of this innovative achievement at all operation sites, and plans to expand the application coverage in the future, achieving full coverage of all wellhead operation positions, and truly converting the technical advantages into safety advantages.
