中国石油网消息：9月1日，川庆钻探自研的CG STEER-175高温旋导工具，在渝西区块某井四开作业中，成功破解造斜段托压的提速难题。在温度达135摄氏度的工况下，该工具首次实现国产旋导在川渝深层页岩气区块一趟钻完成四开全井段作业任务，并刷新了国产高温旋导单趟钻最长进尺和单趟钻最长循环时间等2项纪录。

China Oil News: On September 1st, the self-developed CG STEER-175 high-temperature steering tool by Chuanqing Drilling successfully solved the problem of accelerating the rate of formation inclination change during the fourth opening operation in a certain well in the Yuxi block. Under the working condition of a temperature of 135 degrees Celsius, this tool was the first to achieve a domestic steering tool to complete the entire well section operation tasks of the four openings in the deep shale gas block of Sichuan and Chongqing in a single trip drilling, and set two new records for the longest drilling depth and the longest circulation time in a single trip drilling of domestic high-temperature steering tools.

渝西区块深层页岩气储层地质条件复杂，造斜段托压现象长期制约着国产高温工具在该区域的钻井提速效率。同时，该井目的层龙马溪组下部五峰组地层可钻性极差，轨迹穿层作业易导致钻头快速磨损，频繁起钻会进一步影响作业连续性。针对上述工况，川庆钻探创新应用新型结构设计，有效改善了钻具组合在造斜段的受力状态，作业全程未出现托压现象，更加充分发挥出CG STEER旋导工具的抗高温性能和轨迹控制精度能力。

The geological conditions of the deep shale gas reservoirs in the Yuxi block are complex. The phenomenon of pressure support in the inclined section has long hindered the drilling speed improvement efficiency of domestic high-temperature tools in this area. At the same time, the lower part of the Longmashi Formation and the Wufeng Formation in the target layer of this well have extremely poor drillability. Tracing operations through the formation are prone to cause rapid wear of the drill bit, and frequent well kicks will further affect the continuity of the operation. In response to the above conditions, Cangjing Drilling innovatively applied a new structural design, effectively improving the stress state of the drilling tools in the inclined section. No pressure support phenomenon occurred throughout the operation, and the anti-high-temperature performance and trajectory control accuracy capabilities of the CG STEER steering tool were further fully exerted.

在极端高温环境下，CG STEER旋导工具展现出优异的抗高温性能和轨迹控制能力——工具信号传输稳定，解码正确率达95%，精准将轨迹控制在目的层，实现储层钻遇率100%。与同平台进口工具相比，该井钻井周期缩短15%，标志着国产旋导工具在复杂深层地层中的适配性与稳定性，已具备了与国际先进产品同台竞技的实力。

In extremely high-temperature environments, the CG STEER steering tool demonstrates outstanding resistance to high temperatures and trajectory control capabilities - the tool signal transmission is stable, the decoding accuracy rate reaches 95%, and it precisely controls the trajectory to the target layer, achieving a 100% reservoir drilling encounter rate. Compared with imported tools on the same platform, the drilling cycle of this well is shortened by 15%, indicating the adaptability and stability of domestic steering tools in complex deep formations. It has already demonstrated the strength to compete with international advanced products.

从“跟跑追赶”到“同台竞技”，川庆钻探将不断打磨优化CG STEER旋导工具的核心性能与配套工艺，用自主可控的国产化定向技术服务链条，为深层页岩气的规模化效益开发筑牢安全高效的技术底气。

From "lagging behind and catching up" to "competing on the same stage", Chuanqing Drilling will continuously refine and optimize the core performance and supporting processes of the CG STEER steering tool. With the independent and controllable domestic directional service technology chain, it will lay a solid foundation of safe and efficient technical strength for the large-scale and efficient development of deep shale gas.
