摘要： 本文简要叙述了应用镜质体反射率、甾烷和蒮烷异构化程度指标恢复古热流史的原理和方法,并对准噶尔盆地西北缘的艾参1井做了实例分析。应用结果表明,以往某些镜质体反射率与TTⅠ的关系式不适合于艾参1井,而用甾烷和藿烷异构化程度指标恢复的热流史两者却极为一致,且与其他学者对艾参1井粘土矿物和磷灰石裂变径迹的研究结果吻合很好。重新建立了新的镜质体反射率与TTⅠ的关系式。

Abstract: The principles and methods of reconstructing the thermal history of basins using vitrinlte reflectance f sterane and hopane isomer data are described in this paper with case analysis of well Aican No.1 in the northwestern margin of Junggar Baijin presented. It is suggested that while some of TTI and Ro reiationships used are not suitable for the well, the thermal history of the well reconstructed using stcrane and hopane data is in good accordance wiih that done using day mineral data and fission scars in apatite by other investigators.

Key words: vitrinitc reflectance, sterane isomer, hopane isomer, reconstruction of the thermal history
