在鑽探工作中,为了保証正常鑽进,必須根据地質設計要求及孔內实际情况,采取相应地操作方法。但随着鑽孔的加深,岩层的不同,孔內情况复杂多变,单凭操作者的經驗,是难以掌握判断准确的。因此,在条件允許时,应該通过科学的方法去掌握。本文系根据401队“电流表使用的初步总結”一文整理的。由于該队初次試用,可能欠圆滿,但对于使用电动机的机場,仍有一定的参考价值。
In drilling work, in order to ensure the normal drilling, according to the geological design requirements and the actual situation within the hole, to take the appropriate method of operation. However, with the deepening of the borehole, the rock formation is different, the situation inside the hole is complicated and changeable. Based on the operator’s experience, it is difficult to grasp the accurate judgment. Therefore, when the conditions allow, it should be through scientific methods to master. This article is based on the 401 team “preliminary summary of the use of ammeter” article finishing. Due to the initial trial of the team may be less than satisfactory, but for the airport using the motor, there is still some reference value.
