| 摘 要： | 针对偏心跟管钻具工作环境与受力作用复杂的情况,通过建立跟管钻具在地层中钻进的有限元模型,设定各种边界条件及载荷,运用有限元分析软件ANSYS 12.0对跟管钻具的钻进工况进行仿真模拟,分析钻具在钻进时与地层岩土体相互作用下的应力应变情况。根据模拟分析结果能够更清楚地了解钻具钻进时的应力状态,并对钻具的设计、优化起到指导性作用以及为钻具设计结构的合理性提供了理论依据。

| Abstract: | In view of the complex situations of application environment and force condition of DTH hammer drilling with eccentric simultaneous casing,different boundary conditions and loads were set by the finite element models of DTH hammer drilling in the formation,and DTH hammer drilling simulation was made by the finite element software ANSYSY 12.0.Analysis was made on the stress-strain of the drilling tool in working conditions.Based on the simulation analysis and according to the drilling stress,theoretical basis for the design and optimization of DTH hammer drilling tool in structure rationality was provided. |
