井筒管柱机械校深技术的研究与应用

Research and Application of Wellbore String Mechanical Depth Correction Technique

针对油管传输射孔、薄层卡封需要进行伽玛校深的问题,引进了一套井筒管柱机械校深装置。对该装置进行研究、改进和应用,解决了复杂地面情况下管柱校深问题。该工艺操作简便,成本低,定位精度达到技术要求。

During well testing,both TCP and thin zone plugging need depth correction by gamma-ray positioning.For the limitation of the location condition,sometimes vehicles can't be put in the operation point,well test operation has to be postponed.In order to solve this and other problems,we introduce a set of wellbore string mechanical depth correction device.This technique has some advantages including simple operation,low cost and being able to meet the required accuracy in depth positioning.
