DETECTOR SYSTEM OF SLICKLINE IRREGULARITIES

摘要

Detector of Slickline Irregularities (DILA) is a comprehensive electronic system to proactively detect and assess irregularities presented by slickline due to interventions in the field (production wells) or to a new slickline. It is governed by the principle of eddy currents or eddies or Foucault currents. This comprehensive electronic system allows to detect and assess irregularities of slickline used in interventions in oil wells. It is noteworthy to mention that these lines can vary in diameter depending on the operation to be performed on each well. It comprises: optical encoder, eddy current sensor, eddy current reader, an electronic module for data acquisition and a personal computer. DILA allows to obtain an electronic record by monitoring of the integrity of the slickline used in well service operations, allows interpretation of the data for graphing and keeping records for later use, providing reliability and security to the scanned line. It helps to reduce failures in the slickline as a result of rupture due to deformations for excessive stresses or collisions, which are created within the producing wells, it detects flattening and bending, lack of nickel coating (darkest areas on slickline) porosity and corrosion probably due to acid attack on line during downhole operations.
