根据压裂管柱的压裂施工过程、管柱结构和井下工具特性，建立了压裂管柱的综合力学模型，研究了在施工过程中能够影响管柱位移的4种基本效应。运用相应公式及算法编制了压裂管柱力学分析软件，并结合大庆油田压裂管柱实例进行了力学分析计算。经现场测试，通过软件计算结果与现场实测数据进行比较，误差在合理范围内，满足工程需要。软件所得出的计算结果对于现场压裂作业具有一定的指导意义。

According to the process of fracturing program and the structure of fracturing strings and characteristics of the dowhole tools,a comprehensive mechanical model of fracturing strings is established.The four basic effects which influenced displacement of the fracturing strings were studied.An appropriate formulas and algorithms were used to establish a set of fracturing strings mechanical analysis software.Daqing oilfield fracturing strings was used as an instance to process the mechanics analysis and calculation with the software.According to the results from the field test,the error between the data from software and the field test meets the needs of the error with-in a reasonable range.Therefore,the results obtained from this software have important implica-tions for field fracturing operations.
