南黄海盆地北部坳陷海底烃类渗漏与深部油气属性
|
摘要
采用侧扫声纳和高分辨率地震方法,对南黄海盆地北部坳陷海底烃类渗漏地球物理特征进行分析,发现了与海底烃类渗漏有关的声学特征(麻坑及海底圆丘增强反射及柱状扰动等)。通过对南黄海盆地北部坳陷烃类渗漏区酸解烃的分析,认为烃类气体主要属于热成因气类型。海底地层中发育的接近或直达海底的断层为烃类渗漏提供了运移通道和路径,海底浅表层气体的聚集和渗漏是深部地层中孔隙流体向上运移的结果。
Side scan sonar and high-resolution seismic methods were used to analyze the geophysical characteristics of hydrocarbon seepage in the northern depression of the South Yellow Sea Basin, and the acoustic characteristics related to submarine hydrocarbon seepage were discovered, including hemp pit, submarine dome reflector and columnar disturbance. The acidolysis hydrocarbon in the seepage zone of the northern depression was analyzed. The result shows that hydrocarbon gases mainly belong to thermogenic gas. The faults developed in subbottom close to or direct to the seabed provide seepage migration channel and path, and the gas gathering and seepage are resulted from the upward migration of pore fluid in deep formation.
