满加尔坳陷北部满1井区泥盆系东河塘组沉积成因探讨
|
摘要
东河塘组是塔里木盆地重要的勘探目标层,本次研究在对塔里木盆地满加尔坳陷北部探井岩心颜色、粒度、成分、沉积构造研究的基础上,结合前人研究区东河塘组沉积成因的探讨,将其岩石学特征与沙雅地区和塔中地区进行对比,利用测井曲线、录井岩性剖面的分析,以及地震解释地层等厚图等地质资料,揭示目标层沉积相类型及其特征,并进一步初步探讨了本区的沉积相模型。研究认为该区发育干旱潮坪相,分为泥坪、砂坪、砂泥坪3个亚相。
The Donghetang Fm.is an important exploration stratum in Tarim Basin,somebody has researched the stratum in Tazhong area and shaya swelling,and the depositional facies of Shaya swelling is not barrier coast,the depositional facies of Tazhong area is estuarine facies.This article is based on the observation of the core data of exploration wells in the north Manjiaer depression,and we analyzed the color,granularity,ingredient,sedimentary structure of the core.The depositional origin of the Donghetang Fm.in Shaya swelling and Tazhong area are discussed and the lothology of this area is compared with Shaya swelling and Tazhong area.As well the log data is analyzed and used with the seismic interpretation.The type and characters of the depositional facies in the area are analyzed.It is found the facies of this area is dry tidal flat facies.Last a sedimentary facies model is established for in this area.
