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。 The seismic facies of the Tertiary continental facies in Jizhong depression can be divided into seven types and 19 types. Among them, the typical shape and structure of the typical seismic facies analysis of sedimentary environment has more important significance. These earthquakes are regularly distributed in certain parts of the depression and in the seismic sequence. Some seismic facies, such as mound facies, phloem facies, prograde facies, and facies facies, have a direct relationship with hydrocarbon accumulation.
