In recent years, the deformation and offset of casings in oil wells in part of the oil field in China have been observed. Because this problem is closely related to water injection, particularly to the injection pressure, so we call it an induced event. Observations show significant relative displacement between the axial lines above and below the deformed position of the casing, or the casing is brokened when the displacement is large enough, which means that the rock mass in which the casings are located is...

In recent years, the deformation and offset of casings in oil wells in part of the oil field in China have been observed. Because this problem is closely related to water injection, particularly to the injection pressure, so we call it an induced event. Observations show significant relative displacement between the axial lines above and below the deformed position of the casing, or the casing is brokened when the displacement is large enough, which means that the rock mass in which the casings are located is sheared by horizontal force. The correlation between above casing problem and injection pressure provides a new in-situ evidence to the effective stress law. The mechanism of the problem mentioned must be valuable to the study of induced earthquakes and may be also usefull to the investigation of function of fluid in earthquake process.

近年来,在我国的部分油田普遍发生了一种井孔套管的变形和断错现象,因为它与注水特别是注水压力直接相关,所以称之为注水诱发事件。观察表明,变形套管伴有明显的轴线偏移,严重者完全错断,说明岩体发生了近水平的剪切位移。套变现象与注水压力的相关性为有效应力定律提供了一种新的野外证据,对诱发地震及流体在地震过程中的作用的研究也具有一定参考价值。

In this paper, effective stress for double porosity elasticity model is presented by means of stress analysis for double porosity media elements. It is found that the effective stress law is not unique, it depends on the hypothesis of constitutive equations for multi_porosity media. Diversified effective stress laws for multi_porosity are developed.

This paper presents a simple review about fluid solid coupling theory and mainly refers to the interaction between rock mass and fluid. Several important questions existing in the theoretical study, including effect stress laws,the systematical coupling models, the degree of coupling and the numerical analysis methods, are discussed.Two practical problems in the petroleum exploitation about casing collapse and sand production are taken as examples to make some explication. Therefore, a further development in coupling theory of seepage rock mass will promote the advance of the geomechanics in petroleum industry.
