| 摘 要： | 深水盆地往往为天然气水合物和深水油气的共存区域。天然气水合物既是一种重要的油气资源,又是深水油气开发中引起地质灾害的重要因素。如果能实现深水油气和天然气水合物联合开发,将具有重要的经济价值;然而,目前尚不知两者的共存规律。根据南海北部白云凹陷高分辨率地震资料的综合解释成果,识别出大量的深部油气渗漏现象,包括有利于流体运移的气烟囱构造、深水水道砂体、海底滑坡、多边形断层等渗漏构造,提出了该区天然气水合物可能的成藏模式,指出了天然气水合物富集模式及其与游离气和深水油气渗漏的共存规律。 |
| 关 键 词： | 天然气水合物 游离气 深水油气渗漏 成藏模式 共存 南海 |

| Abstract: | Gas hydrate usually occurs with deepwater hydrocarbon together in the deepwater basin of the northern South China Sea.Gas hydrate is not only a giant potential resource,but also an important factor of geohazard for deepwater oil development.It could have great economic benefit if deepwater oil and gas hydrate could be developed together.However,it is unclear for the distribution of the gas hydrate and deepwater hydrocarbon.Based on the high resolution seismic data of Baiyun Sag in the north of South China S... |
| Keywords: | natural gas hydrate free gas deepwater hydrocarbon leakage reservoir-forming model coexistence South China Sea |
