Abstract：The Middle and Lower Cambrian is an important exploration field in Tarim Basin. Development of the Middle and Lower Cambrian evaporites is one of the key factors to successful Cambrian subsalt exploration and plays an important role in oil and gas accumulation. Therefore,the distribution characteristics and development model of the Middle and Lower Cambrian evaporite are of great significance for oil and gas exploration. Based on the regional geological background,core slice observation and drilling data analysis,this study identifies rock types of the Middle and Lower Cambrian evaporite in Tarim Basin,depicts its spatial distribution and establishes its formative model. The study shows: (1)The evaporites of the Middle and Lower Cambrian in Tarim Basin are mainly salt and gypsum rocks. The Lower Cambrian evaporite is thin and only distributed in the west of the basin without salt accumulation center. The thickness and distribution range of the Middle Cambrian evaporite both increased. Taking Bachu uplift as the salt accumulation center,it is distributed in a large area in Bachu-Tazhong-Tabei area in thick layers. (2)In the Lower Cambrian Xiaoerbulak Formation,the origin of the evaporite was“Sabkha”and“shallow-water evaporative lagoon”in a carbonate ramp. In the Wusongger Formation,the origin of the evaporite was“Sabkha”in a restricted platform. In the Middle Cambrian,the basin was periodically isolated from an open sea and the depositional environment evolved into a drying-evaporative platform. The evaporite distribution had a sedimentary characteristics of salt-gypsum-dolomite-mudstone from inside to outside. The conclusions could deepen the understanding of the dolostone-evaporite paragenesis system in Tarim Basin,providing new reference information for the prediction of Cambrian high-quality caprock and the distribution of effective reservoir cap assemblages in the Tarim Basin. Meanwhile,this study provides an important theoretical support for the Cambrian subsalt exploration.
