| 摘 要： | 弹性条件下的拉伸速率和由于压实作用而不断变化的沉积物密度满足一定的散度方程。通过有限差分方法解该方程可计算盆地的拉伸量。应用该方法对海拉尔盆地各沉积时期进行了计算，取得了较好的效果，这对盆地的形成和演化以及寻找油气靶区等研究具有一定的指导意义。

| Abstract: | The stretching rate and the density of sediments which is continuously changed due to the pressure of overlying deposit under the elastic conditions can be described by certain divergence equation.Using limited difference method the stretching amount of a basin may be calculated.Applying this method the stretching amount of the Hailar basin during various sedimentation stages were calculated,and good results were achieved.It indicates that obtained results may be of guiding significance in the research on the formation and the evolution of the basin,and in prospecting oil gas target areas. |
