随着我国钻探事业的发展,迫切要求用先进的测景仪表来装备钻探机械.特别是金刚石钻进技术的推广,为满足钻进工艺需要,研制一种合适的流量计就提到日程上来了.目前国内生产多种型式的流量计,如涡轮流量计、转子流量计、靶式流量计和电磁流量计等,但尚不能直接应用到钻探机台,因为它们之中有的结构复杂,价格昂贵;有的不适用于输送泥浆介质;有的不能承受高压.近来钻探生产部门经常反映金刚石钻头烧钻现象比较严重.其原因主要是钻头底部缺乏足够的冲洗液.这可以从两个方面采取
With the development of China’s drilling, there is an urgent need to equip drilling machines with advanced measuring instruments, especially the promotion of diamond drilling technology, in order to meet the needs of drilling technology, to develop a suitable flow meter is mentioned on the schedule At present, many kinds of flowmeters are produced domestically, such as turbine flowmeters, rotor flowmeters, target flowmeters and electromagnetic flowmeters, etc. However, they can not be directly applied to drilling machines because some of them are complicated in structure and the price Expensive; some do not apply to the transport of mud media; some can not withstand high pressure. Recently, the diamond production sector often reflects the diamond drill bit more serious because of the lack of sufficient drilling fluid bottom .This can be taken from two aspects
