关于鑽粒鑽进之原理問題,目前还沒有一个完整論点。苏联也正在进行討論。几年來,虽然我們在鑽探效率上、質量上,有了較大的提高,但在理论上仍然是落后的。为了改变这一情况,有必要在鑽粒鑽进的理論研究上,进行一番較長时間的細緻研究工作,以便用技术理論去指导实际工作,进一步提高鑽探工作的技术水平。目前鑽粒鑽进理論,虽然还沒有获得統一的論点,然而基本上是在下边三种说法中进行爭論: 第一种主張是:未被破碎的鑽粒,在軸心压力的参助下对岩石压碎和碾磨; 第二种主張是:已被破碎之鑽粒在軸心压力的作
There is not yet a complete argument about the principle of drilling boring. The Soviet Union is also under discussion. In recent years, although we have made great improvement in drilling efficiency, quality, we still lag behind in theory. In order to change this situation, it is necessary to carry out a relatively long period of careful research in the theoretical study of drilling into bits in order to use technical theories to guide practical work and to further improve the technical level of drilling work. At present, the theory of drilling into grains, although not yet get a unified argument, but basically in the following three arguments for debate: The first claim is: unbroken grain, under the pressure of the core with the help of Rock crushing and grinding; the second proposition is: the broken bits of diamond in the axial pressure for
