为了大搞钻井翻番,尽快推广高压喷射钻井技术,我们参照喷射钻头的结构原理,将现有的普通牙轮钻头改制成喷射钻头,解决了喷射钻头供应不足的困难。 一年来,我们共改制钻头1190只(其中绝大部分是M_1——10R型),据下井使用及现有540只的资料统计,累计进尺91397.6米,累计工作时间9042.0小时,平均进尺为169.25米,平均工作时间为16小时44分钟,机械钻速为10.1米/小时。
In order to vigorously double the drilling, promote high-pressure jet drilling technology as soon as possible, we refer to the structural principle of the jet drill, the existing ordinary roller cone drill bit into a jet, solves the jet drill insufficient supply difficulties. In the past year, a total of 1190 drill bits (most of them M_1 - 10R) have been rebuilt. According to statistics on use of the wells and data from the existing 540, the accumulated footage was 91,397.6 meters and the accumulated working time was 9042.0 hours with an average footage of 169.25 meters , The average working hours of 16 hours and 44 minutes, the penetration rate of 10.1 meters / hour.
