【摘要】 柴达木盆地西南区是青海油田的主要产油区,该区第三纪地层对比划分一直没有统一,从而导致区域性勘探难度增加,影响该区的勘探进程和生产工作。在前人研究的基础上,以层序地层学为指导综合运用岩性、电性、古生物和地震等资料,通过对研究区单井资料的分析和对区域地层特征的研究,得出了柴西南区各地层层序内部特征与层序界面特征,从而建立了柴西南区统一的地层对比与划分标准。更多还原

【Abstract】 The southwestern Qaidam Basin is a major oil-producing region in the Qinghai Oilfield.The stratigraphy of the Tertiary reservoir strata in the SW Qaidam Basin has not been standardized , thus hampering petroleum exploration.Based on previous work and synthesizing lithostratigraphic , well log , paleontological , and seismic data , we propose a sequence stratigraphic framework for the Tertiary of SW Qaidam Basin , with the goal to provide a standard for regional stratigraphic subdivision and correlation.更多还原
