摘要
本文利用地震时间剖面的内部反射结构和外部几何形态等地震相标志,结合古地貌特征的研究,对周口拗陷下第三系核桃园组二段进行了古水流体系和沉积体系的分析。研究表明,充分利用地震信息,对在控制井少的新区寻找隐蔽油藏可提供科学依据。
Using the seismic facies indicators such as internalreflection configurations and external geometric forms in the seismic sections and the study of the paleogeomorphic characteristics, an analysis is given to the ancient current system and the sedimentary system within the second unit of the Hetaoyuan Group in the Paleogene of the Zhoukou depression. It has been proved through practice that making a full use of the seismic information to find out sedimentary bodies, and the application of seismic facies analysis can provide evidences for the exploration of concealed oil pools in non-drilled areas.
