水平井牵引器测井成功率的研究及应用

Research and application of logging with horizontal well tractor

随着钻井技术水平的不断提高,水平井钻井技术在近几年内得到了发展,对水平井测井技术的需求也随之越来越迫切。牵引器作为水平井测井市场中的主力仪器,在水平井测井中得到广泛应用,由于受到钻井技术水平的限制,水平井井身轨迹不可能实现理想状态,可能造成牵引器遇卡,致使仪器机械部件损坏。文章针对水平井牵引器测井时经常发生的故障进行分析研究,提出了解决的方法并实际应用,有利于地质工作者了解井下生产状况,确定更好的施工解决方案。

With the continuous improvement of drilling technology,horizontal well drilling technology developed in recent years.The demand for horizontal well logging technology has been more and more urgent. Tractor as the main instrument in horizontal well logging market are widely used in the horizontal well logging. Due to the limitation of drilling technology,horizontal well bore trajectory can't achieve ideal state. The tractor will meet obstacles and cause the instrument damage of mechanical components. In view of the failure often occurs in the tractor horizontal well logging,this article carries on the analysis and practical application for geological workers to know the downhole production status and to determine the better construction solution.
