随着石油工业的飞速发展,油田钻井速度不断提高,钻杆接头的偏磨问题越来越突出,特别是,当地层硬,井身质量不好的情况下,偏磨更加严重。如据江汉油田的资料介绍,钻一口3000米深的井,全部使用新接头,钻完后己有70%不能使用。由于接头磨损,严重影响钻井速度的提高和钻具的修复,问题相当突出,急待解决。我厂在党组织的领导下,组成三结合试验小组,在“独立自主、自力更生”方针指导下,冲破资本主义国家对我们的技术封锁,以长中国人民的志气和同超级大国斗争的精
With the rapid development of oil industry, the drilling speed of oilfields is continuously increasing, and the partial wear of drill pipe joints is becoming more and more prominent. In particular, partial wear is more serious when the formation is hard and the quality of wellbore is not good. According to the data of Jianghan Oilfield, a 3000m deep well was drilled and all the new joints were used. After drilling, 70% of the wells could not be used. As the joint wear and tear, seriously affecting the drilling speed and drilling tools to improve, the problem is quite prominent, an urgent solution. Under the leadership of the party organizations, our factory has formed a three-pronged experimental group under the guidance of the principle of “independence and self-reliance” and has broken through the technical blockade imposed by the capitalist countries in our technology and has shown the aspirations of the Chinese people and the struggle against the superpowers.
