不同注水压力下射孔套管的ANSYS分析

ANSYS Analysis of Stress on the Perforated Casing in Different Flooding Pressure

根据对油田套管损坏情况的分析,发现大多数套管损坏部位在射孔段。利用ANSYS有限元软件,对套管射孔段建立仿真模型,在不同的注水压力下分析套管的受力情况,为套管的设计和预防套损提供理论依据。

According to the analysis about the failure of casing in oil region, most damages occur on the perforated interval. The paper uses the FEM software ANSYS to establish the realistic model of casing perforated interval, analyzing the stress on the perforated casing in different flooding pressure. The analytic result could supply us with theoretical criteria for the design and casing prevention method.
