• It adopts modular-type design, AC VF driving, being connected to 6300V wire netting;
• The whole set of equipment and associated devices are put in a trolley. Fast-moving of the entire equipment and full setback state of the rig can be realized through lifting and advancing the cylinders, and it is unnecessary to disassembly while being moved between wells;
• Complete with 2-grade reducer for the drawworks which meet the requirements that the maximum test load to be 400t, and the maximum load speed to be 15.m/s;
• Completed with automatic bit feed drill motor, which could be treated as either emergency motor or remote control devices, the mast and substructure can be raised up with a distance of 65m from the wellhead;
• The mast and substurcture adopt spin-up structures, so they can be orderly lifted by drawworks without slipping the wireline, which can decrease the lifting load and save the lifting time efficiently;
• It adopts low etmperature materials and processes as well as heat supplying and warm-keeping measures, so that it can be worked normally at -45℃, and stored at -60℃;
• Security monitoring system, harmful gas detecting system, multi-user communicating system, and highly integrated driller's cabin are adopted to fully guarantee the security and humanity during the operation.
