摘　　要：通过水平层状封闭含油层模型 ,根据弹性理论和地下流体动力学理论 ,结合固体潮理论 ,研究了起潮力对油井动态的影响 ,给出了由起潮力反演含油层应力的方法 .用该方法计算了 1 983年菏泽MS5 .9地震和日本秋田MS7.7地震的应力降 。On the basis of the theory of elasticity and hydrokinetics,effect of tide generation force on dynamics of oil wells is studied refering to the theory of earth tide and by using model of horizontal layered oil bearing formation.A method inverting stress in oil bearing formation by tide generation force is given.The stress drops of two earthquakes are calculated by the method.The results by the method approach results by other methods.
