大国总师一席谈 | 东方物探张少华：打造万米深地的“勘探慧眼”

Core Insights - The article highlights the advancements in China's oil and gas exploration technology, particularly the "Two Wide and One High" seismic exploration technology system developed by Zhang Shaohua, which enables effective detection of ultra-deep oil and gas resources [1][6]. Group 1: Technological Innovations - The "Two Wide and One High" seismic exploration technology allows for the detection of oil and gas resources at depths extending from 5,000 meters to 10,000 meters, making China one of the few countries capable of such deep exploration [5][6]. - The technology incorporates a dual-track design of "satellite remote sensing + ground reconnaissance," which optimizes network layout and addresses blind spots in complex geological structures, significantly improving data signal-to-noise ratios [3][4]. - Innovations include the development of a 300,000-channel high-precision seismic acquisition system and the first wide-frequency controllable seismic source, which can operate between 1.5 Hz and 160 Hz, enhancing deep detection capabilities [5][6]. Group 2: Achievements and Impact - The technology has led to the discovery of significant gas fields, including the "Dina 2" gas field, which contains over 100 billion cubic meters of gas, and has established key gas zones for the West-East Gas Pipeline project [3][4]. - As of the end of 2023, the "Two Wide and One High" technology has supported the discovery of four trillion cubic meter gas fields and three billion-ton oil fields, contributing to national energy security [6]. - The advancements in exploration technology have not only filled gaps in international geophysical exploration knowledge but have also established a foundation for China's independent research and development in exploration technology [4][6].
