The people who do drilling and drilling engineering hope that they can achieve the ideal effect on the efficiency of hole formation and the speed of drill bits when the drilling equipment is purchased. That is, the faster the better the speed of the hole is, and the requirement to complete the drilling of low energy.
Now many construction sites are privately contracted, and the price may be calculated according to the number of holes. Some holes are fixed quantity, and some holes are not fixed, so the more drilling is, the better the benefit is.
In this case, the construction units in the purchase of many factors to consider in addition to rig prices and customer service service areas, but also pay attention to the problem of efficiency rig construction, also is a question of pore forming speed, and a lot of time may hole speed one is considered to rig performance problems another aspect; specific situation is largely limited to the construction site, such as the hardness of the rock and so on; a final but also consider the anchor rig construction in drilling construction in the construction methods and construction technology of attention, this is also a problem of hole construction in speed. The first time in the choice of the rig must be carried out according to the specific construction of the drilling parameters selection, selection efficiency of a most suitable and ideal about construction of the rig, this is a foundation, did not choose the right behind the drill may have to work to achieve a good construction effect in the hard won't another; is to understand the specific geological conditions, a selection and construction process for this case, the following may affect the speed of construction in construction:
1. is the construction point of view, the view of construction selection can be good for a broken rock, probably a lot of demonstration, the corresponding principle in the structure, so in this case select angle of construction is an important factor in drilling speed;
2., considering the hardness and brittleness of rock, it is possible that rock is harder or brittleness is bigger. For construction speed, it is a good information for old saying, so the construction speed of such a rock condition is the most secure.
3., for the medium hard and medium hard rock, the rock breaking effect with high frequency and low impact energy is good, and for hard and hard rock, the rock breaking effect of impactor with low frequency and high impact energy is better.
To sum up, the construction effect is different under different construction conditions. Therefore, according to the specific conditions of construction, the selection of drilling rig and the selection and application of construction technology are the important reasons to ensure the drilling speed.
