塔河地区志留系沉积体系及储层纵向分布特征
|
摘要
利用野外露头、薄片、地震、测井等资料,并结合前人研究成果,进行了构造背景分析。塔河地区受加里东晚期、海西早期、海西晚期和燕山早期构造运动影响,大部分地区缺失志留系,目前主要在西南部钻遇志留系地层,且只保留了志留系下统柯坪塔格组及塔塔埃尔塔格组,发育滨海—浅海碎屑岩沉积体系。在识别出沉积体系类型的基础上,分析了塔河地区志留系有利储层特征,认为其储层纵向分布受构造运动及海平面升降变化控制,并预测其有利储层集中于柯坪塔格组下段、上段及塔塔埃尔塔格组。
Based on the data of outcrop,thin section,seismic data,logging and previous research results,the structural setting in Tahe area is analyzed.The result shows that Tahe area was affected by tectonic movements such as late Caledonian,early Hercynian,late Hercynian and early Yanshan movement.The Silurian,which is absent in most areas of Tahe area,appears in southwestern Tahe area and was only reserved in Lower Silurian Kepingtage Fomation and Tata'ai'ertage Formation,developing tidal flat and continental shelf here.Based on the sedimentary system types,the characteristics of the favorable reservoir of Silurian in Tahe area are analyzed.It is considered that the vertical distribution of reservoir is controlled by tectonic movement and eustatic sea level change.The vertical distribution of reservoir is predicted.The favorable reservoirs converge in lower and upper Kepingtage Fomation and Tata'ai'ertage Formation
