Panjin Liaohe Oilfield Tianyi Petroleum Equipment Co., Ltd. (hereinafter referred to as “Panjin Tianyi Petroleum”) is located in Panjin City, Liaoning Province, and was established on October 23, 2006. The company specializes in the research, development, design, manufacturing, and service of top drive drilling systems (commonly known as “top drives”). It boasts a team of expert technical and service personnel, state-of-the-art production capabilities, and proprietary top‑drive technologies, continuously strengthening its core competitiveness. Through collaboration with leading domestic and international enterprises, the company has grown into a cutting-edge, technologically mature, and fully serviced professional manufacturer of top drive systems.

　　The company’s main top drive models include: DQ90Ⅰ (750 t), DQ70 (500 t), DQ50Ⅰ (350 t), DQ50Ⅱ (350 t, reinforced version), DQ40X (250 t, specially designed for slant‑and‑vertical drilling rigs), DQ40A (250 t, tailored for offshore workover platforms and truck‑mounted rigs), as well as the DQ40LA low‑temperature top drive and hydraulic top drives. In recent years, in tandem with the expansion of its top‑drive business, the company has also developed rotary steerable drilling systems, top‑drive casing‑running units, tong‑type pipe handling tools, and adaptive drill‑pipe torque control systems, each serving specific stages of oilfield drilling operations.

　　The company places great emphasis on product quality and management system development, having obtained the following certifications: on February 14, 2018, it was certified to both the API 7‑1 Standard for Rotary Drilling String Components and Drilling Services and the API 8C Standard for Drilling and Production Hoisting Equipment; on March 8, 2018, it achieved API Q1 certification; and on August 12, 2010, it obtained certifications under the Chinese Occupational Health and Safety Management System, the Chinese Petroleum Health, Safety and Environment Management System, and the Environmental Management System—each of which has undergone three recertifications and remains currently valid. Additionally, on November 28, 2017, the company was certified to the Quality Management System standard.

　　The company places a strong emphasis on technological innovation; its rotary steerable drilling system won first prize at the 2014 Liaoning Province Youth Science and Technology Innovation and Entrepreneurship Competition. Furthermore, its various models of AC‑variable‑frequency top drive drilling rigs received a total of nine science and technology awards between 2011 and 2014, conferred by the Liaoning Provincial People’s Government, the Liaoning Provincial Department of Small and Medium‑Sized Enterprises, and the Panjin Municipal People’s Government’s Science and Technology Awards Review Committee. On November 30, 2018, the company was recognized as a high‑tech enterprise, and in 2019 it was designated a Liaoning Province Intellectual Property‑Advantaged Enterprise.

　　The company enjoys an excellent overall credit standing, with no records of untrustworthy conduct in either the national joint credit information system or the provincial enterprise joint credit information system. In 2018 and 2019, it was recognized as a “Tax Credit Grade A” taxpayer, receiving corresponding incentives for compliance. In December 2019, Yipaike obtained an AA‑minus rating in its corporate credit certification. The company has not been involved in any intellectual property litigation, nor has it incurred any administrative penalties or disciplinary actions related to intellectual property or other matters. Furthermore, the company has no adverse records concerning environmental protection or tax‑related social responsibility.

　　Facing severe market challenges, Tianyi Company has consistently adhered to the Scientific Outlook on Development, steadfastly pursued its strategy of becoming a world-class petroleum production service provider, vigorously pursued reform, and accelerated growth—achieving numerous economic milestones that have impressed its peers, with remarkably stable expansion. In the oil‑extraction process, drilling is a critical operation, and the top drive is the core equipment and power source of the drilling system. In 2019, Sinopec successfully completed drilling Well Shunbei Ying‑1 in the Shunbei Oilfield, reaching a depth of 8,588 meters using Tianyi’s DQ70 top drive, setting a new record for the deepest onshore well in Asia and marking China’s mastery of cutting‑edge ultra‑deep‑well drilling technology. As a national high‑tech enterprise, Panjin Tianyi Petroleum has independently developed the world’s first low‑temperature top drive, the world’s first vehicle‑mounted variable‑frequency top drive, and a rotary steerable drilling system, holding more than 20 national patents and breaking the bottleneck that had long constrained Chinese drilling companies’ entry into overseas markets.

　　At the request of Panjin Tianyi Petroleum, Zhonggui (Beijing) Certification Co., Ltd. adhered to the principles of independence, objectivity, impartiality, and scientific rigor, employing standardized and consistent evaluation methods to conduct both quantitative and qualitative analyses of the company’s reputation as an innovation entity, its innovation resource capabilities, its innovation implementation capacity, and its innovation management competence. Focusing on the company’s core products and technologies, the firm carried out a tiered assessment of its knowledge‑innovation capabilities, encompassing document review, intellectual‑asset appraisal, and on‑site evaluation. By integrating the results from all modules, Panjin Tianyi Petroleum was assigned a knowledge‑innovation capability rating of A.
