一种水域第四系浅层气综合勘察方法
By employing a phased, multi-method approach to explore Quaternary shallow gas in waters, utilizing geochemical exploration, geophysical exploration, drilling, and static cone penetration testing, anomaly zones are gradually delineated and gas pressure values are calculated. This approach solves the problems of low accuracy and efficiency in shallow gas exploration in waters, enabling real-time monitoring and early warning of high-risk areas.

AI Technical Summary
Existing technologies for shallow gas exploration in aquatic environments are inaccurate and inefficient, making it difficult to effectively identify and avoid high-risk areas, leading to potential safety hazards in engineering projects.
The exploration method employs a phased approach that integrates multiple methods, including initial exploration, in-depth exploration, and monitoring stages. It combines geochemical exploration, geophysical exploration, drilling, and static cone penetration testing, and uses technologies such as seismic reflection at different frequencies and multibeam echo sounders to gradually delineate anomaly areas, calculate gas pressure values, and set up monitoring points for real-time monitoring.
It improves the accuracy and efficiency of surveying, reduces costs, and enables long-term real-time safety monitoring and risk warning of high-risk areas, making it suitable for long-distance projects such as cross-sea channels.
