摘　　要：为了明确塔里木盆地志留系柯坪塔格组的沉积特征,通过对岩芯、钻井、测井和地震资料的分析,结合粒度分析手段,对柯坪塔格组上、中、下三段进行了沉积相识别与划分,在该层段识别出扇三角洲、有障壁滨海以及浅海3种沉积相,划分出三角洲平原、三角洲前缘、潮坪、陆棚4种沉积亚相及9种沉积微相。利用地震属性信息并结合砂地比,分析了柯坪塔格组各段沉积相平面展布特征,对今后的勘探开发提供一定的参考依据。In order to clarify the depositional characteristics of Kepingtage formation of Silurian in Tarim Basin, by analyzing the core, drilling, logging and seismic data, combined with the method of grain size analysis, Kepingtage formation is divided into 3 sedimentary facies, which are the delta plain, delta front, tidal flat and continental shelf, and 9 sedimentary microfacies are identified. Based on the seismic information and the thickness ratio of sandstone to formation, the plane distribution of the drawn, providing a basis for further exploration. sedimentary facies of Kepingtage formation is
