中国石油网消息：9月5日获悉，渤海钻探自主研发的“一种超支化两性离子聚合物及其在钻井液中的应用”获得国家知识产权局发明专利授权。这标志着该公司在高端钻井液处理剂领域取得重要技术突破。

China Oil News: On September 5th, it was learned that Bohai Drilling has independently developed "A kind of hyperbranched amphoteric ion polymer and its application in drilling fluid", which has been granted an invention patent by the National Intellectual Property Administration. This indicates that the company has made an important technological breakthrough in the field of high-end drilling fluid treatment agents.

随着油气勘探向深层进军，高温高压地层对钻井液性能提出了更高要求。传统聚合物处理剂在高温高压环境下易失效，影响井壁稳定性和钻井安全。针对这一难题，渤海钻探科研团队成功研发出具有超支化结构和内盐特性的两性离子聚合物。

As oil and gas exploration moves deeper into the earth, the high-temperature and high-pressure formations have placed greater demands on the performance of drilling fluids. Traditional polymer treatment agents tend to fail in high-temperature and high-pressure environments, affecting the stability of the well wall and the safety of drilling operations. To address this challenge, the research team of Bohai Drilling has successfully developed a cationic polymer with a super-branched structure and internal salt properties.

该处理剂集耐温抗盐、高效抑制等性能于一体，经180摄氏度高温老化后仍保持39%以上的降黏率，抑制造浆率最高可达91%，综合性能明显优于常规产品。同时，该产品合成工艺简单，与各类钻井液体系配伍性良好。

This treatment agent integrates properties such as high temperature resistance, salt resistance and efficient inhibition. After being aged at 180 degrees Celsius, it still maintains a viscosity reduction rate of over 39%, and the inhibition rate for pulping can reach up to 91%. Its comprehensive performance is significantly superior to that of conventional products. At the same time, the synthesis process of this product is simple, and it has good compatibility with various drilling fluid systems.

目前，该新型处理剂已在塔里木、大港等油田完成10余口重点井的现场试验，有效保障了复杂地层条件下的井壁稳定和井眼清洁，钻井液性能调控时间缩短60%以上。该技术主要适用于深层、超深层及高温高压井钻井工程，应用前景广阔。

At present, this new treatment agent has completed on-site tests on over 10 key wells in oilfields such as Tarim and Dagang. It effectively ensured the stability of the wellbore and the cleanliness of the wellbore in complex geological conditions, and shortened the time for controlling the performance of the drilling fluid by more than 60%. This technology is mainly applicable to deep, ultra-deep and high-temperature-high-pressure well drilling projects, and has broad application prospects.
