金刚石钻探用的钻杆,是一种高速回转构件.由于钻杆柱细长比很大,钻进时地层多变,因而人们认为,在一般工程施工中,钻杆是受力最复杂,工作条件最恶劣的构件之一.它在钻探装备中所处的地位十分重要.因此各国钻探界及制造厂家都很重视钻杆的研究.近年来国内有关部门也作了不少研究,而且取得了一定进展.本文就国内钻杆性能及其结构的发展趋势问题作初步探讨. 对钻杆的基本要求
The drill pipe used for diamond drilling is a kind of high-speed rotary member. Due to the slenderness ratio of the drill pipe, the strata are varied during drilling. Therefore, it is believed that in the general engineering construction, the drill pipe is the most complex and the work is difficult. One of the worst conditions of the structure. Its position in the drilling equipment is very important. Therefore, the drilling industry and manufacturers in all countries attach great importance to the study of drill pipe. In recent years, domestic authorities have also made a lot of research and achieved Certain progress. This paper will discuss the domestic drill pipe performance and the development trend of its structure. The basic requirements for drill pipe
