7月1日，吉林油田海47区块传来捷报，由长城钻探自主研制的贴壁式电磁波电阻率测井仪首次在外部市场海77F平1井成功应用，施工总进尺达1879米，连续工作时间突破250个小时，平均机械钻速为7.04米/小时，油层钻遇率达95％以上，获得甲方高度评价。

今年年初以来，长城钻探组建高端随钻仪器研发团队，从机械设计、工艺方法、关键部件、电路通信等方面开展攻关，实现集成化电路、贴壁式钻铤等机械设计长度不超过2米，电路板数量缩减60%、机械组件数量缩减40%、整串仪器制造成本降低40%以上，提升了仪器的整体稳定性和可靠性。自2022年贴壁式电磁波电阻率测井仪产业化应用以来，累计施工作业77口井，钻井进尺达7万米。

长城钻探致力于增强核心功能、提高核心竞争力，加快打造高端随钻仪器装备“产学研用”一体化技术平台，以科技创新赋能产品升级。公司先后获得发明专利授权32件，制定国家和企业标准12项，科技成果转化创效突破上亿元，为集团公司高质量发展和保障国家能源安全提供支撑。

On July 1, the good news came from the Hai 47 block of Jilin Oilfield. The wall-mounted electromagnetic wave resistivity logging instrument independently developed by the Great Wall Drilling was successfully applied in the external market for the first time. The total construction penetration reached 1879 meters, the continuous working time exceeded 250 hours, the average mechanical drilling rate was 7.04 meters/hour, and the drilling rate of the oil layer reached more than 95%. Highly praised by Party A.

Since the beginning of this year, the Great Wall Drilling has set up a high-end drilling instruments R & D team to carry out research from the aspects of mechanical design, process methods, key components, circuit communication, etc., to achieve integrated circuits, wall-mounted drill collars and other mechanical design lengths of no more than 2 meters, the number of circuit boards reduced by 60%, the number of mechanical components reduced by 40%, and the manufacturing cost of the whole series of instruments reduced by more than 40%. The overall stability and reliability of the instrument are improved. Since the industrialization of wall-mounted electromagnetic wave resistivity logging instrument in 2022, 77 Wells have been constructed with a drilling depth of 70,000 meters.

Great Wall Drilling is committed to enhancing core functions, improving core competitiveness, accelerating the creation of high-end drilling instruments and equipment "production, research and use" integrated technology platform, with scientific and technological innovation to enable product upgrading. The company has obtained 32 invention patents authorized, formulated 12 national and enterprise standards, and transformed scientific and technological achievements to more than 100 million yuan, providing support for the high-quality development of the group and ensuring national energy security.
