通过对天然气的组成和生物标志物的综合研究,依据实际地质条件,综合分析了自贡西部地区雷口坡组天然气的成因类型和分布规律.结果表明研究区雷口坡组存在三种来源与成因类型天然气:以须家河组来源为主的天然气,主要分布于雷三段储层中;以深层来源气为主的天然气,主要分布在雷一1段储层中;须家河组烃源和深层烃源的混合型成因气,在雷一段~雷三段储层中均有分布.

Study of gas component and biomarks in combination with geological conditions indicates that gas resources in the Leikoupo Formation, west Zigong Region may be divided into 3 types. The gas in the third Member of the Leikoupo Formation was derived from the Xujiahe Formation, the gas in the first Member of the Leikoupo Formation was derived from the depth and the mixed gas was in the Members 1-3 of the Leikoupo Formation.
