| 摘 要： | 利用从钻井岩屑中获取的烃类气体地球化学信息,分析了孔雀1井烃类气体的来源及其纵向上的变化规律、运移方式、运移方向等,指出该井志留系储集层聚集了下古生界烃源岩生成的天然气,气藏中的天然气以扩散和渗透方式发生了垂向上的运移,这种运移一直可以追索到地表。认为孔雀河斜坡具有寻找天然气的潜力和前景,该地区的地表油气化探方法应选择直接烃类法。

| Abstract: | The source of the hydrocarbon gases in Kongque Well 1 and the vertical variation regularities, the migration mechanisms and the migration directions of these gases have been analyzed based on the geochemical data of the hydrocarbon gases extracted from the drill cuttings. The results show that the gas accumulated in Silurian reservoirs source from the Lower Paloezoic source rocks. These gases can vertically migrate to the surface through diffusion and permeation. Investigations of this kind indicate that Kongque River Slope has gas potential and prospect, and the direct hydrocarbon method should be used in this area when conducting oil and gas geochemical exploration. |
