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。 In this paper, the non-linear contact of horizontal well fracturing string is solved by the combination of finite element and gap element. Field measurements show that the calculated results are compared with the measured results, the error is less than 12%, which meets the engineering requirements and provides a reliable theoretical analysis method for the stress analysis of horizontal well fracturing pipe columns.
