目前,在小口径钻探工作中如何能简便、准确地测量钻孔的顶角与方位角,不只是一个急需解决的生产问题,也是一个关系到小口径钻探技术能否更快推广的问题.我们从1977年起开始了小口径罗盘测斜仪的试制工作.这种仪器在生产试验过程中,经过了辽宁、吉林一些冶金矿山等生产单位较长时间的使用,证明技术性能达到了设计要求.1978年11月,冶金部在吉林省冶金地质勘探公司六○四队召开了有全国十四个单位参加的小口径“罗盘、定盘”测斜仪鉴定会.与会同志认为,这种小口径罗盘测斜仪具有灵敏度高、抗震性好、结构简单、使用
At present, how to measure the apex angle and azimuth of a borehole easily and accurately in small-bore drilling is not only an urgent need to solve the production problem, but also a problem that relates to whether the small-diameter drilling technology can be promoted more quickly. The trial production of small-caliber compass inclinometer began in 1977. During the production test, this kind of instrument has been used for a long time in the production units of some metallurgy mines in Liaoning and Jilin Province, proving that the technical performance has met the design requirements. In November 1978, the Ministry of Metallurgical Affairs held a small-caliber “compass, set-plate” inclinometer appraisal meeting attended by 14 units of the country in the 6004th Metallurgical Geological Exploration Company of Jilin Province. Small-caliber compass inclinometer with high sensitivity, good seismic performance, simple structure, use
