In recent years, measurement while drilling(MWD) and underground-oriented control technology have made great progress, and more and more sensors and control units are applied in down hole. For drilling equipment and downhole measurement tools which work for a long time in the underground, the stronger its functions and the more sensors and control actuators used, it means that the greater demands...
With development of auto bit feeding technology, the auto bit feeding technology is one of main development directions of automatic drilling. The drilling quality can be improved in various drilling status, the accident rate in work, the labor intensity, and drilling costs can be reduced. The system composition and control principle of auto bit feeding are introduced, also is the auto bit feeding...
A new type of oil pipe inspection robot will be presented and the structure and function movement of which will be described in this paper, what's more, the obstacle avoidance control system of the robot will be researched in the paper according to the technological problems of the inspection robot in oil pipeline. The results of the simulation experiment in VC++ environment show that the obstacle...
Pipeline robot is a research hotspot in pipeline industry, as the same as research and application in petroleum pipeline .Because that the condition is special in downhole, the performance of downhole crawling robot is different from general pipeline robot. This paper introduces downhole crawling robot, key technology on driving unit Downhole crawling robot can adapt to holes of different diameter...
