伊洛瓦底盆地热-沉降史模拟及构造-热演化特征
伊洛瓦底盆地 热史 沉降史 模拟
font style='font-size:12px;'>
2014/3/31
本文首先运用EASY% Ro反演法对伊洛瓦底盆地由北向南进行了热史的恢复，北部钦敦凹陷的平均古地温梯度为13.0~15.0 ℃/km，中部沙林凹陷的平均古地温梯度为18.0~22.0 ℃/km，南部三角洲凹陷的平均古地温梯度为33.0~37.0 ℃/km.从模拟结果可以看出，盆地由北向南地温梯度逐渐升高，生烃门限的深度由深变浅.然后模拟了盆地的构造沉降史.模拟结果表明，盆地具有幕式构造沉降特征，这...
南海南部边缘沉积盆地构造-热演化历史
南海南部 沉积盆地 构造-热演化模拟 应变速率法

南海南部边缘发育众多含油气盆地，具有可观的油气资源潜力.本文采用基于多期有限拉张模型的应变速率方法对南海南部边缘沉积盆地进行了构造-热演化模拟，并与南海北部边缘沉积盆地的构造-热演化历史进行了对比分析.南海南部边缘晚新生代具有明显碰撞挤压、走滑改造的痕迹，而同时期北部边缘以小规模的张性断裂活动为主，由于构造活动背景的不同，造成了南、北边缘沉积盆地构造-热演化历史的差异.
热磁测量,包括高温磁化率和高温磁化强度测量,是根据热磁曲线转折点的温度(居里点、尼尔点或相变点)鉴定样品中磁性矿物种类的有效方法.本文选取两个人工合成磁赤铁矿样品,利用四种热磁测量仪器分析不同的条件下测得的热磁曲线.依据样品与空气接触程度,将测量环境设为开放、封闭、封闭(通入氩气或氮气)三类.结果表明:热磁测量环境的开放程度对居里点和曲线可逆程度产生极大的影响.封闭环境下测得的居里点较开放环境下的...

盆地内快速剧烈的构造作用可导致热异常，在利用盆地热历史揭示深部动力学过程时，需消除热异常的影响. 本文根据瞬时热传导原理，校正了渤海湾盆地渤中坳陷低热异常，准确地约束了盆地深部动力学状态. 对渤中坳陷内3口典型井进行热流校正结果表明，渤中坳陷古近纪以来快速沉积导致其现今（~60.9 mW·m-2）未达到热平衡（低热异常）. 校正后的热流值平均约为67.4 mW·m-2，比现今高5~10 mW·m-...
查干凹陷是银根—额济纳旗盆地最具勘探潜力的凹陷, 但是查干凹陷及整个银根—额济纳旗盆地的大地热流研究仍为空白, 严重制约该盆地的油气资源的评价. 本文通过测试19口井107块岩芯的岩石热导率和岩石热导率原位校正, 利用协和平均公式计算得到查干凹陷各地层的岩石热导率大小; 并利用9口井的温度数据, 结合岩石热导率数据对查干凹陷的地温梯度和大地热流进行了计算. 研究结果表明查干凹陷具有构造稳定区和构造...
