中国石油网消息：5月18日，由中油测井天津分公司C4271作业队实施的淮南瓦斯治理工程可视化避光纤射孔作业完成全部任务。经现场检测，管外光纤通信良好、无损伤。这标志着该企业自研爬行器避光纤射孔技术首次实现成功应用，可为井下瓦斯及相关气体实施持续监测。

China Oil News: On May 18th, the visualization avoidance fiber perforation operation for the Huainan gas control project, carried out by the C4271 operation team of the Tianjin Branch of China Oil Logging, completed all tasks. Through on-site testing, the external optical fiber communication was found to be in good condition and without any damage. This marks the first successful application of the self-developed crawler avoidance fiber perforation technology by this enterprise, which can enable continuous monitoring of gas and related gases in the wellbore.

施工中使用的避光纤技术和TRAC4900高速爬行器装备，融合了爬行器输送、可视化定位、光纤避障三大优势，有效解决了大斜度井水平井射孔施工中井下光纤防护难题，实现了施工精准度、安全性和时效性的大幅提升，可让井下光纤充分发挥作用。

The optical fiber avoidance technology used during the construction and the TRAC4900 high-speed crawler equipment, which integrate the advantages of crawler transportation, visual positioning and optical fiber obstacle avoidance, effectively solve the problem of underground optical fiber protection in horizontal well perforation construction of high-angle wells. It significantly improves the accuracy, safety and timeliness of the construction, and enables the underground optical fiber to fully exert its function.

为确保施工安全平稳顺利，工程技术团队针对“保护井下光纤”核心需求，精心优化避光纤射孔器结构，全过程实时开展可视化方位监测，确保井下光纤两侧60度范围内无爆破，在射穿地层的同时有效保护了光纤。

To ensure the safety, smoothness and success of the construction, the engineering technology team, based on the core requirement of "protecting the underground optical fiber", meticulously optimized the structure of the fiber protection perforating tool, and carried out real-time visual orientation monitoring throughout the process. This ensured that there was no blasting within 60 degrees on both sides of the underground optical fiber, and effectively protected the fiber while penetrating the strata.

施工中，工作人员操控爬行器平稳穿越井下复杂井段，将避光纤射孔枪串精准输送至设计射孔位置并顺利点火。经检测，井下光纤全程未受到任何损伤，各项指标均达到设计标准。

During the construction process, the workers controlled the crawler to smoothly traverse the complex underground sections. They precisely delivered the fiber optic perforating gun string to the designed perforation position and successfully ignited it. After testing, the optical fibers in the well were not damaged at all, and all indicators met the design standards.

年初以来，为进一步优化和推广爬行器避光纤射孔技术，中油测井持续优化完善爬行器装备，配套避光纤射孔技术研究，持续提升了油气田和新能源领域井下光纤监测全过程服务能力和水平。

Since the beginning of the year, in order to further optimize and promote the crawler-based fiber optic perforation avoidance technology, China Oil Well Testing has continuously optimized and improved the crawler equipment, and carried out research on the fiber optic perforation avoidance technology. This has continuously enhanced the overall service capabilities and levels of downhole fiber optic monitoring in the oil and gas fields and the new energy sector.
