摘要: 冀中拗陷第三系陆相地层的地震相可分为七类十九种。其中,外形和结构较特殊的典型地震相分析对沉积环境解释有较重要的意义。这些地震相有规律地分布在拗陷的一定部位和地震层序中。一些地震相,如丘状相、披复相、前积相和杂乱相与油气聚集有直接的关系。

Abstract: The seismic facies of Tertiary continental beds in the Jizhong depression are elassified into 19 types in 7 groups. An analytical study of the configuration and structure of some of the typical seismic facies is, to a certain extent, essential to the interpretation of depositional environment. These seismic facies follow a definite pattern of distribution in certain sections and seismic sequences. Some of the facies like mounds, drapings, foreset and chaotic facies are believed to be directly related to oil and gas accumulations.
