塔里木盆地下寒武统层序地层特征
Sequence stratigraphy characteristics in the lower cambrian,Tarim basin
摘要
Abstract
The platform facies dolostone which occurs in Early Cambrian strata of the Tarim basin is the main target of cambrian subsalt exploration. On the base of the joint processing shaft seismic section and combining with the results of logging and outcrop. The lower Cambrian strata under the Tarim basin is analysed by using of the methods and principles of sequence and seismic stratigraphy,The sequence stratigraphic framework is es-tablished. The lower Cambrain stratum is divided into one second-order sequence and two third-order se-quence. The third-order sequence is mainly controlled by the ancient tectonic setting,changes of the carbonate deposition rate and accommodation space,and ancient climate condition. The sedimentary model of Cambrian Xiaoerbulake formation in the Tarim basin is the gentle slope-ancient land-restricted platform-open platform-platform margin-gentle slope-deep water continental basin. The favorable reservoir is developed in the platform margin of eastern and northern Tarim basin,the gentle slope of the middle Tarim basin and the southern Heti-anancient land. Two favorable reservoir-seal assemblages have been identified,including:Xiaoerbulake lower-middle formation;Xiaoerbulake upper-wusonggeer formation. It is a mostrealistic exploration field of cambrian subsalt in the Tarim basin.关键词
