拉伸盆地的热机史(thermo—mechanicalhistory)在确定盆地烃蕴藏量方面具有非常重要的意义。因为地质条件有很大的变化,模拟这样的发育史需用一种适应性强的方法。一维有限无法特别适合这种用途。它的应用表明当沉积速率超过约100m/Ma(约300ft/Ma)时,温度的分布是不均衡的。生烃的三种模式中最有利的温度在100~225℃之间,但这并非普遍规律。在界面相当平坦的那些地区内,这种方法以非常小的成本产生极好的结果。与以往相比,它更加清楚地表明了沉积、温度和沉降间的相互作用。
The thermo-mechanical history of the extensional basin is of great importance in determining the hydrocarbon reserves in the basin. Because of the tremendous changes in geological conditions, it is necessary to use a highly adaptable method to simulate this developmental history. One-dimensional is not particularly suitable for this purpose. Its application shows that when the deposition rate exceeds about 100 m / Ma (about 300 ft / Ma), the temperature distribution is not uniform. The most favorable temperatures for the three modes of hydrocarbon generation are between 100 and 225 ° C, but this is not the general rule. In those areas where the interface is fairly flat, this approach produces excellent results at a very small cost. Compared with the past, it shows more clearly the interaction between deposition, temperature and subsidence.
