莺歌海盆地泥底辟构造与天然气运移成藏模式

MUD DIAPIR STRUCTUREAND MODEL OF GAS MIGRATION AND ACCUMULATION IN YINGEHAI BASIN, SOUTH CHINA SEA

莺歌海盆地泥底辟构造为天然气运移提供了良好通道，3000－6000m深处的天然气通过泥底辟构造运移到浅部，并在有利构造部位成藏。

Mud diapir structures in Yingehai Basin, South Chia Sea provided better channels for gas migration, so that gas at 3000-6000m depth were migrated to <3000m shallow reservoirs throught mud diapir structures and traped in favourable structures.
