摘要(Abstract)：
本文用有限元和间隙元相结合的方法，对水平井压裂管柱的非直线性接触进行求解。现场实测表明，计算结果与实测结果对比，误差小于１２％，满足工程要求，为水平井压裂管柱受力分析提供了一种可靠的理论分析方法。
By using the method of combination of finite element with gap element this paper solves the nonlinear contact of fracturing string for horizontal wells.On-site actual measurement shows,compared calculated results with actual measurement ones,the error is less than 12%,meeting the needs of engineering and providing a reliably theoretical analysis method for analysis by force of fracturing string for horizontal wells.
