古构造应力场有限元数值模拟技术已成为古构造应力场研究的一种有效方法，能够实现从动力学机制上定量计算整个含油气盆地古构造应力场的时空变化，对含油气盆地储集层特征描述及油气运聚分析具有重要的理论和实际意义。文中主要介绍了古构造应力场有限元数值模拟技术在含油气盆地研究中的应用现状，并对该技术的发展前景作了进一步展望。

It has been an effective way to study the palaeotectonic stress fields using the technique of finite element numerical simulation
of palaeotectonic stress fields.The technique can quantitatively calculate the whole time-space change of the palaeotectonic stressfields
in a petroliferous basin, which has a important theoretical and practical significance for the reservoir characterization and
analysis of hydrocarbon migration in a petroliferous basin. The paper introduces the present situation of application about the finite
element numerical simulation of palaeotectonic stress fields and discusses its development situation.
