摘    要:根据现代沉积学和层序地层学理论,以塔里木盆地志留系大量的岩心、测井和地震资料为基础,开展地层划分与沉积演化研究.塔中地区志留系分为下统柯坪塔格组沉积、塔塔埃尔塔格组、经历碎屑岩潮坪(局部发育扇三角洲)—内陆棚(泻湖)沉积演化.研究成果对于塔里木盆地储层展布及储盖组合具有参考价值,便于指导下一步油气勘探.

关 键 词:沉积演化  志留系  塔中地区  层序地层

Abstract:According to the modern sedimentology and strata sequence of stratigraphy theory, a number of siluric rock cores, logging and seismic data of Tarim Basin, were synthetically studied in this paper. The result shows that tectonic movement for Gary east middle (Ⅰ, Ⅱ curtain) movement, the late caledonian movement and the early hereynian movement severely affected Tarim Basin Silurian and Devonian. Moreover, fan delta, harrier coastal and Shallow shelf deposi-- tion system were recognized from Tarim Basin Silurian -- Devonian. This paper gives the detailed analysis of sediment characters of these Lithologie sequences of depositional systems and Sedimentary structures and grain size probability, as well as the evolution of sedimentary.
Keywords:Sedimentary evolution  Silurian system  Tazhong area  Sequence Stratigraphy
