| 摘 要： | 综合运用钻井、测井、地震等资料,将黄骅坳陷目前的勘探热点地区——歧北次凹的主要勘探目的层段,即沙一下亚段划分为4个四级层序和8个五级层序,建立了沙一下亚段高精度层序地层格架。结合属性提取和测井约束反演等地球物理方法技术,在高精度层序地层格架约束下对歧北次凹目标层内单个地质体进行多层次多角度的精细刻画,研究其空间展布,并剖析其内部结构特征,分析地质体的控制因素。研究发现:物源供给、断裂陡坡带及断裂转换带对地质体的发育具有重要的控制作用,最后提炼出地质体发育模式,为研究区隐蔽油气藏的勘探和开发提供科学依据。

| Abstract: | Based on integrated analysis of drilling,logging and seismic information,4 fourth order sequences,8 fifth order sequences are identified,according to the high-resolution sequence stratigraphy theory,in the lower part of the first member of the Shahejie Formation(SQEs1x).The SQEs1x is the major exploration target strata in the Qibei sub-sag of the Huanghua depression.A high-resolution sequence stratigraphic framework is established and a geological body of the SQEs1x deciphered through detailed seismic attribute extraction and logging constrained inversion.In the study,we investigate the spatial distribution,inner structures,and their controlling factors of the geological body.Our results show that the sediments supply,faulted abrupt slope zone,and faulted transform zone control significantly the occurrence of the geological bodies. |
