摘　　要：根据理想的水平层状含油层模型 ,分析研究了地震前油井动态变化的机理 .认为由于地壳应力应变的作用 ,使得含油层内的孔隙流体压力发生变化 .当应力增大时 ,孔隙流体压力也随之增大 。On the basis of model of ideal horizontal layered oil bearing formation,a preliminary study on mechanism of dynamic change of oil wells before strong earthquake is made.Pressure of poro fluid in oil bearing formation changes by stress and strain in the crust.The pressure of poro fluid is increased with increase of stress in the crust,then changes of oil output and gas output of oil wells are caused.
