What makes Atlas Copco surface drill rigs special?
Atlas Copco Surface drill rigs ROC®D5, D7, D9 and D7LF Technical specification • Unique, durable cylinder-operated feed system that makes the best use of the rock drill • Long reach makes it ideal for use also in slope stabilization • Supreme productivity thanks to the use of the proven COP-series of rock drills
What are Atlas Copco ROC D5 & D7 drill rigs?
Atlas Copco ROC D5 and ROC D7 drill rigs are designed to handle the most demanding drilling applications in the 35 to102 mm diameter hole range. ROC D5/D7 drill rigs combined a low centre of gravity with high ground clearance to provide optimum manoeuv-rability in all types of terrain.
How does the Atlas Copco hydraulic drilling system work?
The Atlas Copco hydraulic drilling system increases penetration rates while reducing drill steel costs to improve pro-ductivity and over all drilling economy. The robust, hydraulically positioned, support leg can be used to stabilize the drill when moving in rough terrain.
What is Atlas Copco ROC D7?
Atlas Copco ROC D7 has been designed for high productivity in the 64 – 115 mm diameter hole range. The powerful Caterpillar diesel engine, Atlas Copco screw com-pressor and COP 1838 rock drill make this the best performer in its class. ROC D7 has exceptional boom reach to permit more holes to be drilled from each set-up.
What is the ground clearance of Atlas Copco ROC D5?
Ground clearance is a full 455 mm (171/2”) to provide great manoeuvrability in the roughest of conditions. A robust hydraulically positioned support leg ensures drill rig stability when drilling in the roughest of conditions. Atlas Copco ROC D5 combines high productivity with the best total drilling economy to maximize profits.
Can Atlas Copco Drilling Solutions make changes?
However, Atlas Copco Drilling Solutions Inc. is constantly striving for product improvements and enhancements. Accordingly, the right is reserved to make such changes in specifi cations and design that the Company considers in conformity with this policy or are due to unavailability of materials or assemblies.

China s rock drill efficiency
With successful breakthroughs and applications of technologies including the 12000m drill rig, wellbore structure optimization, managed-pressure drilling, efficient drill bits, drilling speed-up, ultra-high temperature resistant and high-density drilling fluids, leakage prevention, cementing, ultra-high temperature and pressure resistant oil testing and completion, and ultra-deep coiled tubing equipment, the number of onshore deep and ultra-deep wells in China has been increasing in recent years. [pdf]FAQS about China s rock drill efficiency
What has been achieved in China's oil & gas industry?
Continuous improvements have been achieved in technical performance indicators such as the drilling cycle, ROP and other metrics. Over 200 wells successfully drilled with MD exceeding 8000m have enabled China to normalize 8000m ultra-deep onshore drilling, with drilling capacity reaching 9000m.
Does rotary non-percussive drilling cause rock failure?
According to the analysis on the SE values at different drilling conditions in rotary non-percussive drilling, the rock failure before the bit is more related to rotary shear than the axial force. Table 2. Calculation of SE based on different drilling parameters in the field test.
Can China normalize 8000m ultra-deep onshore drilling?
Over 200 wells successfully drilled with MD exceeding 8000m have enabled China to normalize 8000m ultra-deep onshore drilling, with drilling capacity reaching 9000m. Moreover, the well depth of TK-1 has successfully exceeded 10000m, making China the second country in the world to successfully drill onshore vertical well with the depth over 10000m.
Does high ROP imply high drilling efficiency in practical engineering?
Note that high ROP does not imply high drilling efficiency in practical engineering because high ROP accelerates the wear of the drilling bit, thereby prolonging the drilling time. Furthermore, the drilling operators possess a few constraints in selecting the correct ROP parameters to optimize the drilling efficiency.
Why do drilling operators need a new index based on rock properties?
However, drilling operators always change drilling parameters to achieve higher drilling efficiency. Hence, a new index that is only related to rock properties and can be successfully applied under different drilling conditions should be developed to define rock properties.
How does cutting a well affect drilling efficiency?
Excessive cuttings will make it difficult to carry drilling fluid, resulting in the deposition of cuttings at the bottom of the wellbore, and the repeated crushing of the rock at the bottom of the wellbore will affect the drilling time and thus reduce the drilling efficiency.
