摘要
古近系沙河街组是华北油田鄚州地区勘探主要目的层之一。长期以来,由于该地区的地层划分未能归一细化,因此极大制约了鄚州地区进一步的勘探工作。充分利用地震、测井、钻井及古生物等资料,结合各级层序界面的识别标志,将地震、测井、钻井和古生物等界面划分统一,建立起地震和地质统一的层序对比关系,并初步分析了地层的发育、分布特征及控制因素,为鄚州地区沙河街组的进一步深化勘探奠定了基础。
The Paleogene Shahejie formation is one of the major exploration targets in Maozhou area,Huabei oilfield.Stratigraphic division has not been normalized,thereby greatly hindered in-depth exploration in this area.Seismic,logging,drilling and palaeontologic data are fully used in combination with identification of various sequence boundaries to construct a consistent stratigraphic correlation between seismics and geology.This research also preliminarily analyzes formation development,distribution and control factors,offering basis for further in-depth exploration in the Shahejie formation of Maozhou area.
