摘要
Diapir structure is an important structural feature with hydrocarbon accumulation, it mainly includes salt diapir and igneous diapir in Tazhong area by seismic interpretation. Salt diapir is simply salt pillow, but it can be divided into three structure features based on genesis: 1) the feature of foot wall of fault resisting; 2) the feature that hanging wall of thrust fault lateral compact; and 3) the feature resulting from buckle folding. The igneous diapirs mainly contain dike and puffrock. Salt diapir formed under compaction background while the igneous formed under protraction background.
