摘要
针对现有气体钻井钻具冲蚀试验装置只能单一模拟气体钻井过程中岩屑对钻具冲蚀磨损的情况,研制了用于模拟气体钻井钻具失效研究的多功能试验装置,给出了气体钻井钻具失效研究的试验方法。多功能试验装置能够在模拟钻具冲蚀磨损的同时,模拟钻具受横向、纵向和扭矩振动等复杂的受力工况下的疲劳断裂试验。装置采用无线遥测动态应变测试分析系统进行试验测试,还可实现远程自动控制,整套装置结构简单紧凑,并且管道封闭,运行噪声小,功能多样,为气体钻井过程中所遇到的钻具失效的相关问题提供了更为全面的研究平台。
The current experimental device for gas drilling tool erosion can only make a single simulation of the cuttings' erosion and abrasion of drilling tools in the process of gas drilling. Considering this problem, a type of multi-functional experimental device used to simulate gas drilling tool failure was developed and the corresponding experimental method was introduced. The device can simulate the erosion and abrasion of drilling tools in the process of gas drilling as well as the fatigue-fracture experiment of drilling tools under complex force conditions, such as lateral, vertical and torque vibrations. It adopts the testing and analysis system of wireless telemetry and dynamic strain to conduct the testing. The experiment is safe and reliable. The device can achieve long-distance automatic control. The whole device is simple and compact in structure, with closed pipelines, low running noise and many functions. It provides a more comprehensive platform for studying the problems concerning drilling tool failure in the process of gas drilling,
