钻压水动力增效装置试验研究

Experimental Research on Hydrodynamic Amplifier of Drilling Pressure

摘要:

在复杂地质条件下进行钻探或处理事故时，常有需要增加钻压的情况。而所选钻机其所能产生的轴向压力是一定的。因此，在钻机选定后如何增加钻压的问题是个非常重要的问题，有时是一个非常急迫的问题。乌克兰国立矿业大学的专家们利用水力动力学原理研制出了一种新型钻压水动力增效装置，可以解决上述问题，值得借鉴。介绍了这种钻压水动力增效装置（ГУОН）的工作原理及其技术性能指标，并通过试验结果与理论计算结果进行了对比。

Abstract:

In drilling engineering practice, sometimes it is necessary to increase drilling pressure for solving the problems of drilling in complicated conditions and treating accidents. One selected drilling machine only gives a constant feed pressure, but the specialists of Ukrainian National Ming University have developed a new hydrodynamic amplifier of drilling pressure based on the principles of hydrodynamics, which can solve the drilling difficulties in complicated conditions. The paper introduced the working principle of hydrodynamic amplifier（ГУОН）and the technical performance index, the comparison was made between the testing results and theoretical calculation.
