Application of Gamma Ray Depth Correction Technology While Drilling in Bohai Completion Perforation Operations
In a perforating completion operation,the depth of the perforating gun is usually determined by comparing the gamma curve of the wireline log with that of the real drill.However,with the increasing difficulty of drilling and development in recent years,the popularity of high inclination and extended reach wells makes wireline logging impossible or difficult to accurately lower to the target zone to complete the perforating operation.This paper mainly discusses the technical process,advantages and disadvantages of gamma-ray depth calibration while drilling and the prospect of its future development.
