中文摘要	为推进我国石油工业发展丰富石油地质理论,根据野外露头及室内分析化验资料,建立8种相标志,识别出索瓦期沉积相类型有:台地相、台地边缘相、盆地相和海陆过渡相、湖泊相.受北部拉竹龙-金沙江缝合带、中央隆起带和南部班公湖-怒江缝合带的影响,沉积相呈近东西向展布,具南北分带的特点.文章分析了索瓦期的沉积特征,总结了该期的沉积模式.根据研究区的生物特征和沉积特征,推断当时气候是温暖、半于旱的.综合分析认为,索瓦组是羌塘盆地很有潜力的油气勘探目的层,其与上覆雪山组地层可构成有利的含油气组合;而双湖-多涌地区是首选的含油气有利区带.
英文摘要	The second largest scale transgression in the Mesozoic occured during the Suowa Stage in the Qiangtang Basin in the Qinghai-Tibet Plateau after the Buqu Stage. The transgression is in a northward di-rection . The whole basin was mainly filled with carbonate rocks. Field outcrops and indoor data analysis re-vealed 8 kinds of sedimentary facies marks fit for this region; and then 5 types of sedimentary facies were rec-ognized : platform facies, platform marginal facies, basin facies, transitional facies and lake facies. Influenced by the northern Lazhulong-Jinshajiang suture zone, Central uplift region and the southern Bangonghu-Nu-jiang suture zone, facies belts extend east to the west. The depositional model was established based on ob-served deposition features. According to biologic features and sedimentary characteristics, it is deduced that the weather was warm and semi-arid during the Suowa Stage. Shuanghu-Duoyong district formed a set of good Source-reservoir-cap assemblage of oil and gas, and can be the most promising target for oil and gas ex-ploration in the future.
