【摘要】：中国南海北部陆坡区是天然气水合物成藏的理想场所,资源潜力巨大。文章基于天然气水合物勘探成果,结合南海北部天然气水合物成藏地质背景,从天然气水合物成藏的温压稳定条件、气源形成条件、构造输导条件和沉积储集条件4方面,系统分析了南海北部天然气水合物成藏的基本地质条件,探讨了南海北部陆坡中部神狐海域、南海北部陆坡西部海域和南海北部陆坡东北部海域天然气水合物的成藏类型与成因模式。结果认为,南海北部陆坡中部神狐海域主要发育扩散型水合物,而南海北部陆坡西部海域主要发育渗漏型水合物,南海北部陆坡东北部海域则发育兼具扩散型与渗漏型特征的复合型水合物。
[Abstract]:China northern slope of the South China Sea area is the ideal place of gas hydrate formation, huge potential resources. The natural gas hydrate exploration based on the results, combined with the geological background of natural gas hydrate reservoir in the northern South China Sea, pressure stability conditions of reservoir temperature from natural gas hydrate, gas forming conditions, structural conditions and depositional conditions in transporting storage 4 system analysis, the basic geological conditions of gas hydrate formation in the northern South China Sea, discusses the northern slope of the South China Sea in Shenhu area, northern slope of the South China Sea waters west of the northern slope of the South China Sea and northeast sea natural gas hydrate reservoir types and genetic models. The result is that the northern slope of the South China Sea middle Shenhu area mainly developed diffusion type hydrate however, the western waters of the northern South China Sea is mainly developed seepage type hydrate, northern slope of the South China Sea in the northeast is the development of both diffusion and seepage The characteristic compound hydrates.
