摘要
针对连续油管自有深度计量设备在井下作业中难以精确定位的问题,介绍深度误差的产生来源和国内外目前常用的理论,计算校深、人工井底校深、机械套管接箍定位器校深及无线套管接箍定位器校深4种连续油管井下定位方法。
In view of the problem that coiled tubing＇s depth is difficult to know when it is downhole operating,the reasons of depth error and calculation depth correction method,depth correction based on artificial bottom hole,mechanical casing collar locator and wireless casing collar locator depth correction methods are introduced in this paper.These four depth correction methods are in common use,based on analysis of these depth correction methods,which should be preferentially developed and which should be developed in long term plan are proposed.
