【摘要】 海拉尔-塔木察格盆地在成盆期和改造期不同构造应力场作用下形成不同类型的构造带和配置关系.为研究不同类型构造带的特征及其与油气的关系,根据地震资料解释和典型剖面构造组合规律,以及构造发育的位置、时间、延伸方向、断裂与褶皱的关系、展布形态及成因,在盆地内共识别出3种与油气密切相关的构造带——变换构造带、断层相关褶皱构造带和滑脱构造带;分析3种类型构造带形成的应力背景和构造特征,发现构造带上不但发育多种类型圈闭,而且紧邻烃源岩,其上所发育的断层还为油气运移提供通道.结果表明,3种类型的构造带为油气勘探的有利区带.更多还原

【Abstract】 Different types of structural belts developed owing to distinct tectonic stress field during the formation and reformation stage of the Hailaer-Tamtsag basin. To understand the features of different types of structural belts and the relationships between them and hydrocarbons, three types of structural zones-fault-related fold structure zone, detachment structure zone and transfer structure zone have been found from the location, time, bearing of trend, order of faulting and folding, distribution and origin of the tectonic development, with which correlate hydrocarbons tightly, on the basis of the interpretation of seismic data and the analysis of structure feature of representative section. Three types of structural zones are abundant in hydrocarbon, because there are many types of traps in structural zones and they are near the source rocks, furthermore, the faults having developed in structural belts serve as effective passages for oil migration through the analysis of their stress field and structural attitude.更多还原
