依据连续介质力学的理论，采用有限元数值模拟方法，通过平均应力将固体应力场与流体压力场有机结合，并以辽河油田现今构造应力场为例，探讨了构造应力与构造热应力对多孔介质中油液不同的驱移作用。研究表明：具挤压特征的构造应力场对盆地油气宏观分布有重要意义，油液有从高应力区向盆地内以主干断裂和软弱带为代表的低应力区迁移的趋势。温差引起的局部应力相当于孔隙压力的作用，能较好地模拟低洼带的油气向周围高点迁移的特点，也是重要的驱动因素。二者联合作用驱动的流体运移速度场能更好地解释现今油田的分布特征，并对预测油气聚集的优势区有指导意义。
According to the theory of continuum mechanics, the finite element numerical simulation method is used to combine the solid stress field with the fluid pressure field through average stress. Taking the tectonic stress field in Liaohe Oilfield as an example, the effects of tectonic stress and tectonic thermal stress on porous media Oil in the different role of the drive. The results show that tectonic stress field with crushing characteristics is of great significance to the macro distribution of oil and gas in the basin. The migration of oil from the high stress area to the low stress area represented by main faults and weak zones in the basin tends to occur. The local stress caused by temperature difference is equivalent to the effect of pore pressure. It is also an important driving factor to better simulate the migration of oil and gas in the low-lying belt to the surrounding highs. The combination of these two factors can better explain the distribution characteristics of the present oilfields and provide guidance for the prediction of the dominant areas where oil and gas accumulate.
