| 摘 要： | 通过对钻井岩心和测井等资料的研究，认为川西南地区下三叠统嘉陵江组存在着混积潮坪、开阔台地、局限台地和蒸发台地4种沉积相类型。嘉一期主要发育混积潮坪相和开阔台地相，嘉三期主要发育开阔台地相，嘉二、嘉四、嘉五期主要发育局限台地和蒸发台地相。选取并研究地层厚度、灰岩厚度、白云岩厚度和颗粒岩厚度等四种能反映沉积环境和沉积相的地质因素，指出了每个层段的沉积相平面分布特征。

| Abstract: | According to the study of core and well logging data, it is recognized that the mixed tidal flat, the open platform, restricted platform and evaporative platform were developed in Jialingjiang Formation. Mixed tidal flat and open platform developed in the first Jialingjiang period, open platform developed in the third JialinKjiang period, restricted platform and evaporative platform developed in the second, the fourth and the fifth Jialingjiang periods. The facies distribution of four key formations were pointed out after thorough study of four geologic factors that could embody sedimentary environment and facies, which is the thickness of formation, limestone, dolostone and grainstone. |
