东营凹陷南坡西段红层地球物理特征及储层预测
Geophysical and reservoir feature of redbed, south slope of Dongying depression
摘要
Abstract
At the sedimentary period of the first member of Kongdian formation (Ek1, ) and the lower submember of fourth member of Shahejie formation ( Es4') , the red clastic rocks sediments, which mainly belong to sheetflood lake facies, are consisted of purple mudstone interbed sandstone and many phases igneous bodies in south slope of Dongying depression. And, it is very difficult to predict the red beds reservoir distribution. The author investigated the lithologic association and the seismic reflection characters of the upper submember of EK1, .studied the red beds lithology, physical properties, electrical properties and velocity characters. The study shows that the mudstone and igneous rocks developed in the top of upper submember of Ek1, ,and the strong amplitude reflection refers to the interface between igneous rock and mudstone. In the bottom of upper submember of Ek1, there develops sandstone interbedded mudstone and igneous rocks. Both the difference between sandstone and mudstone and the difference between sandstone and igneous rock result in the same seismic reflection characters including the middle-high frequency and middle-weak amplitude. This paper analyzed the seismic attributes distinguishing sandstone from seismic reflection. It also indicated that the combination the acoustic impedance inversion constrained by logging data with GR inversion can predict the red beds reservoir distribution effectively.关键词
