渤海海域歧南断阶带明下段河湖交替相沉积
|
摘要
现有的单一曲流河相认识无法准确全面概括歧南断阶带范围内储层展布特征,为了有效地指导断阶带范围内明下段储层预测及油田勘探,综合利用岩心、古生物、测井、地震等资料,在沉积特征及古地貌重新分析的基础上,对研究区沉积相类型进行了重新认识。研究结果表明:明下段沉积时期歧南断阶带范围内存在湖相沉积,但由于其位于凹陷边部,湖平面的频繁升降变化导致断阶带位置处周期性的暴露与淹没,从而发育河湖交替相,纵向上条带状的曲流河相砂体与席状的湖泊浅水三角洲砂体交替出现。该发现可以有效地改善后期调整井的实施及剩余油的挖潜。
The reservoir distribution characteristics in the Qinan fault step belt can't be fully and accurately summarized by the existing single meandering river facies model. In order to guide the reservoir prediction and oilfields development,the sedimentary characteristics and paleo-topography are analyzed by means of multi-parameter analysis,such as core data,paleontology,well logging and seismic data. The sedimentary facies type in the study area is finally reinvestigated. The results show that lacustrine deposition exists in the Lower Minghuazhen Formation of Qi'nan fault step belt. However,the study area is located at the edge of the sedimentary center,and the periodic fluctuation of the lake level makes large area in the fault belt zone expose and flood periodically. Thus,the fluviallacustrine facies mainly develop in the fault-step belt. The sheet lake sand and belt fluvial deposits alternate vertically. Guided by the new facies type theory,the adjusting wells drilling and the remaining oil exploitation are efficiently improved.
