The Intelligent Drilling Computer Moniter System is an advanced scientific research result, which combines the computer techniques with drilling technology, and involves monitoring techniques, identification algorithm etc. The system can be equiped on the field rig quickly and conveniently. It can produce the constrat conditions for drilling parameters automatically, and identify the down hole conditions intelligently so that it can enhance the drilling efficiency and minimize hole problems. It can also trace the track of drilling hole, and predict whether hitting the designed target, and establish the field drilling data base.
