摘要： 应用磷灰石裂变径迹长度分析技术,选定澳大利亚扇形模型,沿可能性最大的3种不同热史路径,对冀南地区Q-5井下白垩统的磷灰石裂变径迹长度分布进行了数值模拟。通过与实测磷灰石裂变径迹长度分布的比较,确定了该井合理的地质演化历史。模拟研究结果表明,Q-5井在距今70×106a时,白垩系达到其演化历史上的最大埋深(3500m);之后发生构造抬升并遭受剥蚀,白垩系的最大剥蚀量为2500m.

Abstract: Applying the technique of apatite fission-track length analysis, selecting Australia fanlike model, and along three most possible paths of thermal history, this paper makes numerical simulation of the analytical length distribution of Lower Cretaceous in Q-5 Well, Minan area. Through comparison with the measured length distribution, the reasonable geological evolution history of this well is determined. The simulation study shows that Cretaceous of Q-5 Well has ever been in the maximum burial depth (3 500m) of its evolution history 70 million years ago, followed by undergoing tectonic uplift and denudation, and resulting in the maximum eioded bickress of it is 2 500m.

Key words: apatite, fission-track dating, distribution, numerical simulation, Cretaceous
