摘要

底辟构造是油气聚集的重要类型,通过地震解释对塔中地区底辟构造进行研究.结果表明:塔中地区主要发育盐底辟和岩浆底辟构造2种类型,盐底辟构造样式主要为盐枕构造,从成因上进而分为断裂遮挡型、逆冲断裂上盘侧向挤压型和纵弯褶皱型;岩浆底辟构造样式主要有岩墙、岩被.盐底辟构造主要在挤压环境下形成,基底隆起控制了盐底辟的发育位置,断裂及褶皱控制了盐底辟的形态;岩浆底辟主要在拉分环境下形成,基底卷入逆冲断裂及NE向调节断裂对岩浆底辟发育具有重要控制作用.塔中地区盐底辟和岩浆底辟构造及其伴生构造可以形成良好圈闭.
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,(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.The frontier shape was controlled by fault and fold and the later controlled by both basement involved thrust fault and NE trend tear faults.It has intimate relations with hydrocarbon.The diapirs and related structures can form traps that later become important exploration targets.
