Advance of automatic intelligent drilling techniques

After the introduction of the rotary steering drilling, geologic sterring drilling and other new drilling techniques, the next advance of drilling technique is expounded,which are composed of the framework of the automatic intelligence drilling technique.Through the research on new drilling techniques such as seismic:while drilling and near-the-bit measurement technique,the prediction while drilling and au- tomatic control are realized.Through the intelligent drill pipe technique,the high-speed transmission of downhole data,ground data and control command are established to generate a drilling system of closed loop,thus realizing the automatic intelligent drilling.
