The source of the hydrocarbon gases in Kongque Well 1 and the vertical variation regularities, the migration mechanisms and the migration directions of these ga ses have been analyzed based on the geochemical data of the hydrocarbon gases ex tracted from the drill cuttings. The results show that the gas accumulated in Si lurian reservoirs source from the Lower Paloezoic source rocks. These gases can vertically migrate to the surface through diffusion and permeation. Investigatio ns 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.
