| 摘 要： | 讨论了利用磷灰石裂变径迹资料反演热演化史的综合分析法．这一方法综合了Ｓｉｍｐｌｅｘ和ＭｏｎｔｅＣａｒｌｏ方法的特点．初值选择采用ＭｏｎｔｅＣａｒｌｏＢｏｘ选择法，而反演迭代则应用Ｓｉｍｐｌｅｘ方法．由于应用了ＭｏｎｔｅＣａｒｌｏＢｏｘ，从而保证了初值在某一限定区域内的随机性选择，避免了目标函数陷入局部极值区而使反演失真的情况．在地质条件约束下，它可以成功地获得目标函数极小值或极小值邻域内的极值以及它们对应的热史的解．应用理论模型，验证了本方法的有效性和稳定性．在初值偏离真值较远（２０－５０℃偏差）的情况下，本方法也可以获得满意的解．以中国东部某凹陷井中实测磷灰石裂变径迹长度分布和退火年龄资料为实例，进行了热史的反演计算模拟，结果清楚地解释了样品所处地区的构造和沉降史．

| Abstract: | The combinative analysis method of thermal history inversion with apatite fission tracks has been discussed in the paper.It cornbnes two modelling techniques,the Monte Carlo method and Simplex method.The Monte Carlo Box used to generate random numerical data gives initial values for geothermal inversion.The Simplex method is for searching appropriate geothermal temperature.The combination of the two methods can avoid tripping in a local minimal position for the object function and give a suitable solution of thermal history.The utlizable and stable text has been taken by the inversion calculation of a theoretical model. Even the difference between the initial and theoretical values is 20-50℃,the suitable results of the inversion can be got.The example of thermal history inversion has been calculated with apatite fission track data.The sample came from an oil well of Eastern China. The result of thermal history inversion gives a clear reflection of structural and sedimental development. |
