摘要: 对柴达木盆地北缘马海-大红沟凸起区的勘探成果及油气成藏条件(包括烃源岩、储盖组合、构造与演化特征、成藏类型等)的分析结果表明,该区油气主要来源于周围的侏罗系生油凹陷,具有油气源多、储层厚度大、油气运移距离远、圈闭发育和油藏分布多的特点。对其油气成藏主控因素的分析结果表明,柴达木盆地北缘发育的3大古凸起区是今后勘探的有利目标。

Abstract: The essential oil and gas pool-forming conditions of the uplift in the northern margin of Qaidam Basin including source rocks,assemblages of reservoirs and cap rocks,tectonic characters and its evolution,and types of pool-forming were analyzed. Oil and gas accumulated on Mahai-Dahonggou paleo-uplift mainly come from the adjacent Jurassic hydrocarbon-generation depression. The pool is characterized by more sources,thick layers,a long distance of oil-gas migration,abundant traps and large scale pools. The analysis on the main pool-forming controlling factors of the area shows that three paleo-uplifts will be the potential exploration targets in the northern margin of Qaidam Basin.

Key words: northern margin of Qaidam Basin, paleo-uplift, oil and gas pool-forming, main controlling factors, potential exploration target
