中国石油网消息：7月2日获悉，中油海工顺利完成大宁-吉县区块某深层煤层气井台压裂施工作业，为该区块资源安全高效开发提供了可靠支撑。

China Oil News: On July 2nd, it was learned that China Oil Offshore Engineering successfully completed the fracturing operation of a deep coalbed methane well platform in the Daining-Jixian block, providing reliable support for the safe and efficient development of the resources in this block.

深层煤层气储层埋藏深、压力高，压裂施工需要大排量、长时间连续作业，传统刚性管汇在高频振动与挟砂液冲蚀下容易出现疲劳刺漏。对此，项目部在施工中将泵车出口的金属硬管线更换为高压柔性软管，利用软管的柔韧特性有效吸收震动、降低应力集中，从源头上提升了现场施工本质安全水平。

The deep coalbed methane reservoirs are buried deep underground and have high pressure. The fracturing construction requires large flow rates and continuous operation for a long time. Traditional rigid manifold systems are prone to fatigue leaks under the impact of high-frequency vibration and sand-laden fluid erosion. To address this issue, the project team replaced the metal hard pipelines at the pump vehicle outlet with high-pressure flexible hoses during the construction process. By leveraging the flexibility of the hoses, they effectively absorbed vibrations and reduced stress concentration, thereby significantly enhancing the intrinsic safety level of on-site construction.

在施工期间，面对夏季多雨、设备高负荷运转等复杂工况，项目部全面落实全过程安全管理，将隐患排查融入每道工序。同时，通过创新“压前交底核查—压中实时监控—压后闭环评估”安全管理模式，并借助液控装置远程投球功能，实现了人员不进入高压区操作，进一步保障了施工人员安全。

During the construction period, in the face of complex working conditions such as heavy rainfall in summer and high-load operation of equipment, the project department fully implemented all-round safety management and integrated potential hazards into each process. At the same time, by innovating the "pre-pressing briefing verification - in-process real-time monitoring - post-pressing closed-loop assessment" safety management model and leveraging the remote ball-throwing function of the hydraulic control device, it enabled personnel to operate without entering the high-pressure area, further ensuring the safety of construction personnel.

通过此次系统性改造与严格管控，项目部高质量完成全部压裂施工，压力全程稳定，成功率达100%，并实现能耗降低10%、作业成本下降5%，安全管控与现场执行获甲方高度评价。

Through this systematic renovation and strict control, the project team successfully completed all the fracturing operations with high quality. The pressure remained stable throughout the process, with a success rate of 100%. Moreover, energy consumption was reduced by 10% and operation costs decreased by 5%. The safety management and on-site execution were highly praised by the client.
