| 摘 要： | 通过钻井、岩芯和测井等资料的分析，清水河组清一段划分出1个长期基准面旋回、2个中期基准面旋回和5个短期基准面旋回。MSC1中期基准面旋回主要为辫状河三角洲沉积，MSC2中期基准面旋回为湖泊相沉积，局部地区夹有辫状三角洲沉积，极易形成岩性油气藏。区域性隔层发育在非对称型长期基准面旋回的上部，有利的储集体主要分布于中期基准面上升的早期。

| Abstract: | Based on the principal of base-level cycle, one long-term stratigraphic cycle, two intermediate-term stra-tigraphic cycles and five short-term stratigraphic cycles can be identified in Mem. 1 of Qingshuihe Formation (K1q1) through the drilling data, cores and well-log data. In the MSC1 of intermediate-term stratigraphic cycle, the main deposition is braided-river delta. In the MSC2 of intermediate-term stratigraphic cycle, the main deposition is of lacustrine facies , with some deposition of braided-river delta in the local area. This kind of configuration makes it very comfortable for the development of lithological reservoirs. The regional interlayer develops in the top of unsymmetrical long-term stratigraphic cycle. The favorable reservoir is mainly formed during the early period when the intermediate-term base-level ascended. |
