中国石油网消息：9月1日，由川庆钻探70288队承钻的泸201H6-3井套管顺利下至预定井深，完钻井深7338米，一举刷新泸州区域深层页岩气井完井最深纪录，为深层页岩气高效开发积累了宝贵的现场实战经验。

China Oil News: On September 1st, the casing of the Lu 201H6-3 well, which was drilled by the 70288 team of Sichuan Qingzhi Drilling Company, was successfully lowered to the predetermined depth. The total well depth reached 7,338 meters, setting a new record for the deepest well completion in the deep shale gas area of Luzhou, and accumulating valuable on-site practical experience for the efficient development of deep shale gas.

泸201井区属于典型的泸州深层页岩气井，地层埋藏深，井底温度高，地下地质条件复杂。施工期间，该队依托井下实时数据动态调整钻井参数，有效提升了深部地层单趟钻进进尺与纯钻时效。同时，优化深井复合钻进钻具组合，有效降低了深部地层钻头磨损、减少了起下钻频次。

The Lushan 201 well area is a typical deep shale gas well in the Lushan area. The formation is deeply buried, the bottom of the well has high temperature, and the underground geological conditions are complex. During the construction process, this team relied on real-time data from the wellbore to dynamically adjust the drilling parameters, effectively increasing the drilling footage and pure drilling efficiency in the deep strata. At the same time, they optimized the composite drilling tool combination for deep wells, effectively reducing the wear of the drill bit in the deep strata and reducing the frequency of raising and lowering the drill string.

针对深层钻井常见的掉块、沉砂等问题，该队严格执行深井携砂循环制度，每趟钻完充分大排量循环洗井，避免岩屑床堆积造成卡钻、阻卡。对易垮塌层、破碎层实行“慢起、稳下、多循环、勤划眼”精细化操作，保障井下工况长期稳定。

For the common problems such as blockage and sand settling in deep drilling, this team strictly implements the sand-carrying circulation system for deep wells. After each drilling operation, they conduct thorough high-displacement circulation and well flushing to prevent the accumulation of rock debris from causing stuck or blocked drilling. For layers prone to collapse and fragmentation, they adopt "slow starting, stable descent, multiple circulations, and frequent reaming" for precise operations to ensure the long-term stability of the wellbore conditions.

此外，该队依托值守型钻机轻量版智能化硬件，借助智能监测设备及川庆钻探自主研发的启能智能钻井系统，全天候采集分析施工数据，实现钻井工况可视化管控，彰显了数智化赋能深层页岩气安全高效施工的优势。

Furthermore, this team relies on the lightweight version of the's intelligent hardware, along with intelligent monitoring equipment and the self-developed Qianqing Drilling's Intelligent Drilling System by the company. They collect and analyze construction data around the clock, achieving visualized control of drilling conditions and demonstrating the advantages of digital and intelligent technology in enabling safe and efficient construction of deep shale gas.
