We should have seen a lot of grooved drill pipe in geological exploration engineering, so what are the matters needing attention in the use of it? It is estimated that a large part of you are relatively confused about this, and I will tell you about it next.
1. the application of grooving drill pipe needs to be in the rated drilling distance of drilling equipment, according to the main parameters of the drilling distance type specifications of the selection of the matching drill pipe.
2. It is made of special geological exploration pipe of mining geology and its matching joint head by friction welding, so it has very good follow-up and high tensile strength, and can be used in common exploration and gas discharge. When working in hard rock layer, coal seam or other special natural environment, it is necessary to determine the drilling depth according to the specific material physical performance index and main parameters of drill pipe.
3. When grooving drill pipe and drill bit supporting facilities are used, the drill pipe should exceed the diameter of drill pipe in general, and special attention should be paid to the situation of drill equipment and drill pipe at all times during the whole process of drilling. If stuck and sudden death often occur, stop drilling immediately or drill slowly after drilling to ensure that the drill pipe does not bend and deform oblate.
4. The grooving drill pipe should be gently tightened manually when drilling, to ensure mutual coordination (thread class), and can not be directly drilled with drilling equipment to avoid damage to the drill pipe.
5. If the bending deformation of drill pipe after application exceeds the requirements specified in the standard or thread damage leads to the failure to work under normal conditions, it should be timely scrapped and properly handled or returned to the factory for maintenance.
6. According to the requirements specified in the standard, the drilling depth of the drill pipe shall be ensured to avoid the loosening of the drill pipe due to the drilling depth to achieve the application degree of the drill pipe.
