PCL测井技术简述及应用实施问题的若干探讨

Discussion on PCL Logging Technology and Some Implementation Problems

自上世纪八十年以来,随着钻井技术的不断提高和成熟,井眼轨迹也变得日趋多样化和复杂化,从最早的垂直井到现在的定向井以及水平井,井斜不断增大,为了适应这种愈加复杂疑难的井况,新兴的钻杆输送测井技术也随之应运而生。为此,文章以PCL湿接头式钻杆输送电缆测井的方式为出发点,重点探讨其在定向井中的应用实践及遇到的问题,以供参考。

Since the eighty years of the last century, with the continuous improvement and maturity of drilling technology, the well trajectory has become increasingly diversified and complicated, from the earliest vertical wells to the present directional wells and horizontal wells. In order to adapt to this increasingly complex and difficult conditions, the emerging drill pipe transport logging tech- nology 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.
