摘　　要：中、低渗透或流度较小的油藏进行试井工作时,所获取的资料基本上是密封断层过渡段的特征,利用斜率加倍关系来识别井附近密封断层存在并计算距离往往令人不满意。利用渗流基本微分方程、叠加原理、镜像反映方法,对井附近线性密封断层模型的方程进行推导,得出了利用过渡段的资料确定其存在和计算距离的关系式,并通过具体实例证明该方法的可行性。在试井解释中,对甄别井附近密封断层的真伪有较大的帮助。Conducting well testing in the mid-low permeability or the lower mobility reservoir,the slope of the sealing fault straight line nearby the well which is twice the slope of the Horner line cannot usually observed,Most of them exhibit the fault transition. It is difficult to estimate the distance to the fault by the traditional analysis method.according to the basic concept of the basis partial differential equation,the superimposition theory and the image response, the paper derives the analytic equation for calculating the distance to the fault which is based on a single sealing fault model. The reliability of the method is verified by the field real data. In interpret,we can identify the existence of the sealing fault by the aid of it.
