中国石油网消息：5月26日，由西部钻探固井公司自主研发且具有完全自主知识产权的补偿加压式井口密封工具，在吐哈油田吉阜5井插入式表层固井作业中圆满完成现场试验。

China Oil News: On May 26th, the compensatory pressurized wellhead sealing tool independently developed by the Western Drilling Well Cementing Company and possessing complete independent intellectual property rights successfully completed the on-site test in the Jiufu 5 well of Tuha Oilfield during the insertable surface cementing operation.

该工具在实际工况下的密封可靠性、操作便捷性及补偿加压功能得到进一步验证。

The sealing reliability, operational convenience and compensation pressurization function of this tool have been further verified under actual working conditions.

吉阜5井由长城钻探50058钻井队承钻，井深825米，采用插入式表层固井工艺。为精准验证补偿加压式井口密封工具的综合性能，技术团队量身定制了试验方案，重点检验了工具在反复插拔、循环泥浆及管内加压等关键工况下的表现。

The Jiufu 5 well was drilled by the 50058 drilling team of Changcheng Drilling Company. The well depth is 825 meters and the insertion-type surface cementing technology was adopted. To accurately verify the comprehensive performance of the compensatory pressure-type wellhead sealing tool, the technical team specially designed a test plan, focusing on testing the tool's performance under key conditions such as repeated insertion and extraction, circulation of mud, and internal pressure increase in the pipe.

最终，吉阜5井固井施工作业顺利完工，试验期间未对正常施工造成任何影响，各项试验任务均达到预期效果。该工具的成功应用，为插入式固井施工提供了更加安全高效的井口密封解决方案。

Ultimately, the cementing operation of Well No. 5 in Jiufu was successfully completed without any interference to the normal construction process during the test period. All the test tasks achieved the expected results. The successful application of this tool has provided a safer and more efficient wellhead sealing solution for the insert-type cementing operation.
