“深海一号”建成国内最大海上气田 我国深水油气工程建设能力大幅提升

Core Insights - The "Deep Sea No. 1" gas field is China's most challenging deep-water gas field, characterized by the deepest operational water depth, highest formation temperature and pressure, and significant exploration and development difficulties [1] Industry Development - China's deep-water oil and gas engineering capabilities have significantly improved in recent years, achieving a transition from shallow to ultra-deep water operations [1] - The equipment technology has reached a world-class advanced level, indicating a strong competitive position in the global market [1] Project Specifications - The second phase of the "Deep Sea No. 1" project features a maximum operational water depth of nearly 1000 meters, with the highest formation temperature reaching 138 degrees Celsius and the highest pressure exceeding 69 MPa [1] - The total designed well depth exceeds 60,000 meters, and the main production facilities span a geographical distance of over 170 kilometers, making it the deepest and most extensive deep-water gas field developed independently by China [1] - The project faces extreme challenges due to the combination of "deep water, deep layers, high temperature, and high pressure" [1]
