In recent years, China has made successive major breakthroughs in ultra-deep well drilling, successfully advancing the drilling of two 10,000-meter wells: Well Shendi Tako-1 in the Tarim Basin, Xinjiang, and Well Chuanke-1 in the Sichuan Basin. In these two highly challenging projects, the 50 MPa mechanical seal washpipe jointly developed by Beijing Petroleum Machinery Co., Ltd. ("Beishi") and JJC has operated stably for more than 7,700 cumulative hours as core equipment, providing strong support for drilling operations through outstanding stability and reliability and contributing to efficient development of ultra-deep oil and gas resources.
To support China's advance into deeper formations, Beishi and JJC have kept innovating and jointly developed a Mechanical Seal Washpipe that works stably for long periods at 70 MPa, reaching the highest pressure level in the world. This breakthrough not only removes a technical bottleneck for the industry but also demonstrates outstanding reliability in field applications, further strengthening China's technical edge in deep-earth engineering.
Marching into the deep earth is an unavoidable path for the national energy strategy. JJC will stay focused on "localizing deep-earth development equipment", drive equipment upgrades through innovation, provide more advanced and more reliable solutions for deep oil and gas resource development, and help China's deep-earth engineering scale new heights.
