| 摘 要： | 根据柴达木盆地北缘红山地区的露头、钻井、地震、CEMP资料,采用高分辨率层序地层学观点,对红山地区白垩系犬牙沟群进行了长期、中期基准面旋回层序划分,建立起了犬牙沟群层序地层格架。在此基础上对长期基准面旋回层序进行了沉积相分析,研究认为:两个长期基准面旋回分别对应于犬牙沟群上、下段;犬牙沟群下段物源来自南缘柴达木古隆起,主要为辫状河三角洲沉积;犬牙沟群上段物源来自北缘褶皱山系,主要为冲积扇沉积。并重点对该区的烃源岩和犬牙沟群下段的储层、圈闭特征、成藏条件、油气显示等进行了全面分析,指出Ⅳ号断块为上盘(F7断层以上)的主要勘探目标,红北1、红北2、红北3圈闭为下盘(F7断层以下)的主要勘探目标。

| Abstract: | According to the materials of exposure,drilling,seismic data and CEMP in Hongshan area of northern Qaidam Basin,with the theory of high-resolution sequence stratigraphy,the sequence stratigraphic framework of the Quanyagou Group is established,based on the sequence division of long term and mid-term basic level cycles of the Group. Sedimentary facies analysis is thereby conducted on the long term basic level cycle sequence. It is considered hat two long term basic level cycles accord with the upper and lowe... |
