塔中地区火山岩与油气藏关系研究

Research of the Relationship Between Lava and Hydrocarbon in Tazhong Area,Tarim Basin

塔里木盆地虽在许多层系中获得工业油气流 ,但在火山岩中还没有突破。火成岩与油气关系包括 :火成岩与生油岩的关系 ;火成岩对油气运移的关系 ;火山活动与油藏关系等 ;与火成岩有关的油气藏圈闭类型有 :火山岩岩颈刺穿圈闭、超覆、披覆背斜圈闭、火成岩脉侧向遮挡圈闭、抬升淋滤型圈闭。

Although industrial oil and gas have been obtained in the many stratums of Tarim basin , we haven’t broken through.Relationship between lava and petroleum include the fellowing aspects:the relationship between lava and source rocks,infection of the lava to petroleum movement ,the relationship between lava and petroleum pools etc.The type of oil and gas reservoir trap about igneous rock : lava neck transpierce trap ,overlap ,cover anticline trap ,igneous dike lateral seal off trap,lifted leach trap,touch metamorphic type etc.
