根据钻井、测井和地震资料，研究了塔里木盆地北部艾协克—桑塔木地区下石炭统含盐层系的沉积特征，恢复了早石炭世沉积岩相古地理环境，对含盐层系的垂向层序、地化特征、沉积环境和成盐机理作了初步探讨，建立了研究区下石炭统含盐层系的成盐模式。认为该区下石炭统的含盐层系不仅具有良好的储盖配置，而且由于盐体的塑性流动形成了一系列重要的含油气构造，具有良好的油气勘探远景 Based on the drilling, well logging and seismic data, the sedimentary characteristics of the Lower Carboniferous salt-bearing strata in the Aikeke-Sangtamu area in northern Tarim Basin were studied, and the lithofacies-paleogeographic environment of the Early Carboniferous was restored. Vertical sequence, geochemical characteristics, sedimentary environment and salt-forming mechanism were discussed. The salt-forming model of the Lower Carboniferous saline system was established. It is considered that the Lower Carboniferous saline system in this area not only has a good reservoir-cap configuration, but also has a series of important petroleum-bearing structures due to the plastic flow of salt bodies and has a good prospect of oil and gas exploration
