Discussion on PCL Logging Technology and Some Implementation Problems

Since the eighty years of the last century, with the continuous improvement and maturity of drilling technology, the well trajectory has become increasingly diversifed and complicated, from the earliest vertical wells to the present directional wells and horizontal wells. In order to adapt to this increasingly complex and diffcult conditions, the emerging drill pipe transport logging technology also came into use. This paper focuses on the application practice and the problems in the directional well with the way of the PCL wet joint drill pipe and the cable logging.
