摘要
前人认为准噶尔盆地南缘阜康断裂带—北三台地区的异常高压形成机制主要与泥岩压实作用和黏土矿物膨胀作用有关,通过对研究区地层异常高压形成原因的分析,结合构造活动和异常高压分布特征,认为持续不断的水平挤压作用造成北三台地区五梁山断层南斜坡区形成压力封存箱,沿断裂持续不断的高压流体供给和异常压力封存箱是该区异常高压形成的主要成因。
Based on previous studies,it was recognized that the abnormal pressure formation mechanism of Fukang fault belt-Beisantai area in southern margin of Junggar basin is mainly related to compaction of mudstone and expansion of clay minerals.This paper suggests from the abnormal pressure genetic analysis integrated with tectonic activity and abnormal pressure distribution that the continued horizontal compression resulted in forming pressure compartment in the south slope of Wuliangshan fault in Beisantai area,and the continued high pressure fluid supply along the fault and the abnormal pressure compartment are the main genesis for forming abnormal pressure.
