The Critical Technology Research on Rotary Steering Drilling System

In order to overcome the shortcomings of slide steering technology, the rotary steerable drilling technology is a new technology developed, this technique represents the highest level of drilling technology development. At the same time, rotary steerable technology is becoming one of the world-class technical problems, and there are a lot of research scholars at home and abroad. Domestic rotary steerable drilling technology research started late, therefore, developed with our own intellectual property rotary steerable drilling technology can significantly improve our oilfield services company's market competitiveness, and generate enormous economic benefits. The paper focuses on the static thrust against rotary steerable systems, rotary steerable drilling technology on the overall composition, tools and software, When using the rotary steerable drilling technology for drilling operation, it does not require frequent tripping you can achieve a tree-dimensional trajectory control, and this technology not only has greater advantage of smoother wellbore trajectory and extending a distance, but also has important significance for ensuring the well trajectory quality, increase drilling speed and efficiency. And for complex structure wells at present the development of special reservoir needs to have the important meaning. In order to provide technical reference for the development of domestic rotary steerable drilling tool.
