中国石油网消息：8月11日，西部钻探固井公司自主研发的“深井大尺寸套管插入式固井装置及工艺方法”获得国家知识产权局发明专利授权，标志着这个公司在高端固井工具原创性技术领域取得重大突破，进一步夯实了深层油气勘探开发核心技术优势。

China Oil News: On August 11th, the "Deep Well Large-Diameter Tubing Insertion Type Cementing Device and Process Method" independently developed by the Western Drilling Cementing Company was granted an invention patent by the National Intellectual Property Administration. This marks a significant breakthrough for the company in the original technology field of high-end cementing tools, further strengthening its core technological advantages in deep oil and gas exploration and development.

该专利依托西部钻探重点科技项目“深井大尺寸套管插入式固井关键工具的研制”，精准破解了深井、超深井固井领域长期存在的技术瓶颈。当前，国内油气勘探开发持续向深层、超深层推进，长封固段大尺寸套管井作业频次大幅增加，传统固井工艺弊端凸显。

This patent is based on the key scientific and technological project of Western Drilling, "Research on Key Tools for Insertion-Type Cementing of Large-Diameter Casing in Deep Wells and Ultra-Deep Wells". It has precisely solved the long-standing technical bottlenecks in the field of deep and ultra-deep well cementing. Currently, domestic oil and gas exploration and development is continuously advancing towards deeper and ultra-deep layers, and the frequency of long-segment cementing operations with large-diameter casing has significantly increased. The drawbacks of traditional cementing techniques have become more prominent.

针对行业痛点，这个公司研发团队创新研发出一套适配深井大尺寸工况的套管插入式固井装置及配套工艺方法。其中，核心研发的双球阀双通道钻杆水泥头，首次实现深井插入式固井胶塞替浆与精准定量替浆，彻底解决了传统理论计算替浆量的误差风险，大幅压缩施工时长、优化水泥浆稠化效果；井口密封循环装置可实现套管与钻杆环空的可靠密封，胶塞碰压装置能够完成井下精准碰压，通过井口、井下双重密封保障体系，从根本上保障了固井质量和施工安全。

In response to the industry's pain points, the R&D team of this company innovatively developed a set of casing-insertion type cementing devices and supporting process methods suitable for deep well and large-sized working conditions. Among them, the core research of the double-ball valve double-channel drill pipe cement head has for the first time achieved the replacement of slurry and precise quantitative replacement of slurry for the deep well insertion-type cementing plug, completely eliminating the error risks of traditional theoretical calculation of slurry volume, significantly reducing the construction time and optimizing the thickening effect of the cement slurry; the wellhead sealing circulation device can achieve reliable sealing of the casing and drill pipe annulus, the cement plug pressing device can complete precise pressing in the wellbore, and through the dual sealing system at the wellhead and wellbore, fundamentally guaranteed the cementing quality and construction safety.

此前，这个公司已在井口密封核心技术领域形成成熟的技术储备与产品体系，多项自研工具完成现场实证。下一步，该公司将持续深耕油气固井核心技术研发，深化“研产用”一体化协同创新，不断丰富高端自主化固井工具产品矩阵，以硬核科技实力助力西部钻探产业升级与高质量发展。

Previously, this company has already established a mature technical reserve and product system in the core technology of wellhead sealing. A number of self-developed tools have completed on-site verification. In the next step, the company will continue to deeply focus on the research and development of core technologies for oil and gas cementing, deepen the integrated collaborative innovation of "research, production and application", continuously enrich the product matrix of high-end independent cementing tools, and use its cutting-edge technological strength to assist the upgrading and high-quality development of Western Drilling.
