Hilong HL125S High-Steel Grade-Sulfur Resistant Drill Rods Selected in 2023 Shanghai Innovative Product Recommendation Catalog

Date 2023-07-31

(Shanghai, July 27, 2023) The Shanghai Municipal Commission of Economy and Informatization recently released its 2023 Shanghai Innovative Product Recommendation Catalog. The HL125S High-Steel Grade Sulfur Resistant Drill Rod for Complex Wells in Sulfur-rich Oil and Gas Field independently developed by Shanghai Hilong Oil Drilling Tools Co., Ltd. was included in the catalog, making it a key recommended innovative product in Shanghai.

HL125S is one of Hilong's independently developed 'three high' series products and features higher steel grade, high strength, high torsional resistance, and high sulfur resistance. It effectively addresses the performance bottlenecks of drill pipes that are used in harsh oil recovery environments, including issues such as hydrogen sulfide-resistant stress corrosion performance, insufficient torsional strength, and poor hydraulic performance, particularly in sulfur-rich deep wells, ultra-deep wells, and large-displacement wells. This product has significantly improved the safety and reliability of drilling and production in deep wells and complex wells in harsh H2S gas reservoirs environments.

Hilong is the first domestic Chinese company to develop and achieve large-scale production and market application of this level of product. With the extensive use of Hilong HL125S High-Steel Grade Sulfur Resistant Drill Rods overseas and the vigorous development of domestic oil and gas resources, HL125S is expected to contribute further to the safe and efficient extraction of oil and gas resources in harsh environments both domestically and internationally.

The Shanghai Innovative Product Recommendation Catalog is compiled by the Shanghai Municipal Commission of Economy and Informatization, which handles the application submission process and provides expert evaluation. The Shanghai Innovative Product Recommendation Catalog Editing and Review Committee then discusses the catalog before its public release. The selection of innovative products using cutting-edge technology aims to encourage the application of new technologies, drive industrial transformation and upgrading in Shanghai, and foster enterprise innovation. The Catalog reflects the forefront of annual scientific and technological innovation and application in Shanghai and is highly significant for demonstrating the strength of the industry.
