| 摘 要： | 应用高分辨率层序地层学方法在南海北部陆坡神狐海域天然气水合物的有利聚集区二级层序划分基础上共可划分出7 个三级层序，且在三级层序格架控制下，神狐海域可识别出席状、楔状、透镜状、丘状、充填状等5 个地震相和16 个地震亚相，沉积相发育以浊流和泥流为主。神狐海域沉积环境演化的总体特征以海平面下降为主，从层序C 到A 发育半深海--深海相到浅海相的地层，从上陆坡到下陆坡主要发育半深海--深海相地层。

| Abstract: | Based on the partition of second sequence，the sequence can be divided into seven third-order sequences by applying high resolution sequence stratigraphy in Shenhu area of northern slope of South China Sea， where gas hydrate is more valued． Under the control of third-order sequence，five seismic facies including sheet， wedge shape，lenticular，mound，filling，and sixteen seismic subfacies can be distinguished in the Shenhu waters． Sedimentary facies development is given priority to the turbidity current and mud flow． The overall features of sedimentary environment evolution of Shenhu area is sea level falling，with development of the strata of bathyal-deep facies to shallow facies from sequence C to A． The bathyal-deep facies are from up continental slope down． |
