The Northern Carnarvon Basin is located at the southern end of the North West Shelf of Australia. It was developed by rifting during the Jurassic-earliest Cretaceous. Heat flow and thermal maturity in seven wells, from three sub-basins, Rankin Platform and Exmouth Plateau of the Northern Carnarvon Basin, were modelled using BasinMod 1D program. Multiple thermal maturity parameters were used to constrain the influence of anomalously low vitrinite reflectance. Those Tmax data with reliable quality can be applied to correlate with vitrinite reflectance, establish thermal maturity and calibrate the modelled results. The modelled results indicated that the measured maturity data in some wells were consistent with the rift heat flow model (Jarvis & McKenzie) associated with the Jurassic rift and the earliest Cretaceous seafloor spreading events. The maximum values of heat flow were in the range from 67mW/m2 (Jurabi-1) to 105mW/m2 (Bowers-1) in the Exmouth and Barrow Sub-basins. On the Exmouth Plateau, the maximum values of heat flow were modelled to be 72mW/m2 in the Jupiter-1 well and 78mW/m2 in the Investigator-1 well. These maximum values were modelled to occur during syn-rift phase, which were 29-88% and 33-37% greater than their current heat flow values in the sub-basins and on the Exmouth Plateau, respectively. This study suggests that maturity indicators are less diagnostic of rifting thermal histories if the maximum thermal effect is associated with Cretaceous and Cainozoic burial in this basin.

Wallace G. Dow 1977年提出在半对数直角座标系下，利用实测的镜质体反射率。与其对应深度的线性相关关系回归直线即称成熟度剖面估算地层剥蚀厚度的方法。本文根据镜体反射率主要受热力。其次受有效加热时间的影响且具不可逆性，对的方法从理论到应用上作了进一步的探讨，并给出了通过镜质体反射率与深度的线性关系恢复地层剥蚀厚度的三种方法。

在对南阳油田东庄次凹烃源岩评价和一维、二维地质建模研究的基础上，利用IES盆地模拟软件对东庄油田的南69井、南77井、东9井和东10井以及过东庄次凹的一条二维测线L450-612.5进行了烃源岩热演化史模拟研究。模拟结果表明：①东庄次凹核三段和核二段烃源岩主体处于生油窗内，镜质体反射率Ro介于0.5%～0.8%间，现今生油门限深度约为1920m，门限温度约为87℃；②二维烃源岩热演化模拟显示，廖庄组开始沉积时（距今大约27Ma），东庄次凹核三段Ro达到0.5%，现今Ro为0.7%～0.8%，处于中等成熟阶段早期；核二段距今约20Ma时，Ro达到0.5%，现今Ro为0.60%～0.65%，处于低成熟阶段；核一段至今仍未达到生油门限；③在距今27Ma时，二维测线L450-612.5的成熟度和温度模拟剖面显示，油气开始生成时的门限深度为2000m，门限温度为93℃，大于现今的门限深度和门限温度。

对文安斜坡石炭-二叠纪（C-P）。煤系特征，尤其是煤的煤岩显微组分组成和煤及煤的各显微组分的元素组成特征的研究表明，本区煤中镜质组含量占绝对优势且较富氢。本文还研究了新生代该煤系的再次埋藏和该区下第三系岩浆活动以及煤系中多层辉绿岩侵入的热力作用对其成熟度的各自影响程度，认为本区已发现的煤成油气藏：大体分布在平均Ro为1.0%～2.0%的苏桥地区，与早第三纪岩浆活动有密切关系。岩浆热力影响有效地促进了煤系烃源岩的热演化和成烃转化，而破坏作用则不大。
