当前,苏联岩心钻探技术和工艺处于先进行列,了解其发展过程和今后的趋向,对我们或许是有益的。苏维埃政权建立初期,因钻探技术落后,给普查勘探工作带来极大困难。1927年全国仅有35台进口钻机,岩心钻探工作量20300米,钻探速度不超过80～90米/台月。 At present, the Soviet core drilling technology and technology are in the advanced ranks to understand its development process and the future trend may be beneficial to us. In the early days of the establishment of the Soviet regime, the drilling technology was backward and brought great difficulties to the census exploration work. In 1927, there were only 35 imported drilling rigs in the country, with a core drilling workload of 20,300 meters and a drilling speed of no more than 80 to 90 meters per month.
