摘　　要： 莺歌海盆地泥底辟带异常高温高压的中深层目的层是该盆地新的油气勘探领域。根据新钻探的两口深探井(X井、Q井)地质地球物理综合解释及测井、录井资料,探讨该盆地中深层目的层天然气的运聚成藏条件,分析了中深层目的层在高温高压环境下的封盖体系,指出该区存在质量相对较好具高突破压力的泥岩封盖层;结合烃源岩有机地球化学分析的结果,认为莺歌海盆地中深层具有良好的烃源条件。盆地中深层具有广阔的油气勘探前景,预测了盆地中深层的有利勘探区带。 The middle-deep beds are very important new hydrocarbon exploration area in the Yinggehai Basin where there are some mud diapir belts with abnormal high temperature and pressure. The migration and generation of hydrocarbon and hydrocarbon trapped system with the abnormal temperature and pressure in the middle-deep beds are comprehensively studied based on the data of the geophysical explanation and well logging in two new exploration wells (Well X and Well Q). There is a relative good mud cover system with high broken pressure and a good reservoir combination. The geochemistry analysis suggests that the source rocks in the middle-deep beds are good at generating hydrocarbon, which shows a potential for oil and gas exploration in the basin.
