连续卡点仪器原理及应用

Principle and Application of HFPT

连续卡点仪器是一种在钻杆遇卡时能准确、迅速测到卡钻位置的工程仪器,文章从设备原理和现场使用两个方面阐述连续卡点测井仪。除常规井,它同时适用于大斜度井,乃至水平井的井况,是真正的测井式测卡方式,能通过测井曲线直观、准确诊断卡点位置,提高效率,缩短工期,在油田安全开发过程中不可或缺。

HFPT is an engineering instrument which can accurately and quickly measure the stuck position when the drill pipe is stuck.From two aspects of principle and application describe HFPT.It is suitable for highly deviated wells and even horizontal wells.It is a real logging measuring method,which can diagnose the stuck position directly and accurately through the logging curve.To improve eff iciency and shorten the construction period,it is very important in the process of oilf ield safety development.
