摘要:

春光油田位于准噶尔盆地西部车排子凸起,经历了多期强烈构造运动,地层缺失严重,残余地层分布不均。
综合运用地震、岩芯及测井资料,在对不同级别层序界面识别基础上,结合地层基准面旋回分析,并依据地层接触关
系,对春光油田古近系、白垩系残余地层对比方法进行研究,最终建立了地层发育模式,对该油田残余地层的细分对比
具有指导意义。研究结果表明,通过对不同级别层序界面的识别及地层旋回分析结果所建立的地层格架,可使春光油
田古近系、白垩系地层划分对比具有等时性。不同成因类型地层,其对比方法有所差异,建立的地层对比方法及对比
原则适用于春光油田小层对比,可用来有效识别不同成因类型地层的缺失层位及缺失厚度。

Abstract:

Chunguang oilfield is located on the Chepaizi uplift in western Junggar Basin,which has undergone multi-phase
intense tectonic movements,and is characteristic of a serious strata loss,and uneven distribution of the residual strata. Using
seismic,core and log data,and based on the stratigraphic base level cycle analysis and on the stratigraphic contact,we made
researches on methods for residual stratigraphic correlation of the Paleogene and Cretaceous strata in Chunguang oilfield,
and established a stratigraphic model,which is instructive to the subdivision and contrast of the residual strata. Results show
that the subdivision and contrast of the Paleogene and Cretaceous strata in Chunguang oilfield can be isochronous,through
the stratigraphic framework established on different levels of sequence boundary identification and analysis of stratigraphic
cyclicity. Comparison methods vary for different genetic types of formations. The strata correlation method and contrast
principle established in the paper are applicable to small layer contrast of Chunguang oilfield,and can be used to effectively
identify the missing formations and thickness of different genetic types of formations.

Key words: Junggar Basin, Chepaizi area, Chunguang Oilfield, residual stratum, sequence boundary, strata correlation
