With the rapid development of modern industrial technology, diamond has increasingly become an important industrial raw materials, widely used in metallurgy, coal, petroleum, machinery, optical instruments, electronics industry and space technology sector. Diamond with its hardness crown the world's first place of all things and difficult to replace the object. In particular, the rapid development of synthetic diamonds in recent decades, but also its multi-purpose performance, low prices are developing more use of the field. Small diameter diamond drilling is an effective way to significantly improve drilling speed and engineering quality and shorten the exploration cycle. In recent decades, with the joint efforts of scientific research, teaching and production units, small-diameter diamond drilling has made great achievements, more and more show its superiority, by the prospecting and infrastructure construction workers welcome, show A broader prospect.

Assess the use of a diamond bit is good or bad, mainly drill bit drill speed, drill footage and unit footage, diamond consumption of three indicators. The current driller should strive to reduce the perimeter of the drill bit as an important goal by increasing the drill bit. Improve the drill bit is a comprehensive index, it involves a wide range, but also a measure of grass-roots unit management level and technical level of an important indicator. To improve the service life of diamond bits, in addition to the selection of high-quality diamond drill bits, improve the workforce awareness, attention to team building, carry out training,Diamond Drilling Tools strict implementation of the system, but also should grasp the following links:

(1) the new drill into the hole before the hole with the outside of the hole with the appropriate fit, but also to drill diameter and core diameter corresponding. The beginning of drilling when the initial pressure is small, until the new drill lip shape run-in corresponding to the hole at the end of the ring, and then apply normal pressure.

(2) drilling technical parameters of the size of the rock with the rock to adapt, and with reference to the unit drill head to adjust the consumption of footage.

① axial pressure is generally not large, the initial pressure is small, broken rock smaller than the complete rock formation, artificial pregnancy diamond diamond bit than the natural pregnancy bit drill small, footage too fast to control the pressure and speed, with particular attention to the tendency of large pressure The Like drilling in the drill wire clip damage too fast, indicating that the pressure is too large, coupled with insufficient water supply, easily lead to drilling.

② speed and drilling speed is proportional to maintain a certain linear speed (greater than 2.0m / s) in order to give full play to the diamond drill bit grinding rock,Diamond Drilling Tools improve hourly efficiency, reduce the role of their own consumption, the number of broken broken rock should be appropriately reduced, Inlaid diamond drill, should use the diameter drill and reamer, to avoid high speed.

③ pump and pump pressure, in conditions permitting, the pump a little more (30 ~ 50L / min) than the small good. While maintaining the corresponding pump pressure, which can reduce the drilling of water leakage caused by the phenomenon of burning, but not because of the amount of water is too large and the erosion of the drill bit into a groove (the main reason for the ridge is rinse Containing a lot of rock powder).

(3) hole and emulsion cleaning fluid cleaning is to improve the life of the drill bit can not be ignored one of the contents, in addition to the requirements of the installation of the circulatory system and the hole in the metal debris immediately washed, fishing, grinding, suction, Clean the emulsion to replace the dirty emulsion. Drilling before the big water punching, to try to use polyacetamide low solid mud as a rinse solution, it can improve efficiency,Diamond Drilling Tools reduce drill wear and lubrication drill.

(4) Selection of drills: In addition to the selection of the program, pay special attention to the use of broken matrix using HRC45 ~ 50 or so drill bit, slip the formation of the use of carcass hardness is relatively soft, small number of fine drill bit or fine table drill bit. Adhere to the drill line in line with the use of rotation, insist on each time to measure the drill bit specifications and fill the card, insist on every 5min measurement of a machine on the foot, master drilling speed changes, adhere to timely grinding drill nozzle, sink, Minimize drill bit damage.

(5) often check the double-pipe joint single-action performance, short section and reamer, retainer and reed seat and drill bit, drill bit and reed diameter with the gap must meet the requirements, the field reed should be equipped with 3 to 4 specifications , To prevent the core block and fall off.

(6) often observe the rig pressure gauge, adhere to the pump pressure gauge, power ammeter, power to grasp the situation within the hole, timely adjustment of drilling parameters.

(7) the use of rope core drilling process, due to the rope to take the core to reduce the number of drilling down, reducing the drill hole wear, damage and damage to the hole wall collision opportunities, and the gap between the drill pipe and the hole wall is small, The end of a smooth turn,Diamond Drilling Tools so that the life of the drill bit has been greatly improved.
