AUTOMATED OPTICAL INSPECTION OF WIRE-WRAPPED WELL SCREENS

摘要

Methods and systems for automatically inspecting a wire-wrapped well screen are provided. A camera may capture an image of a portion of the scree n including at least two facing edge portions of adjacent wraps of wire defini ng a slot therebetween. A thickness of the slot may be determined based on the image, for example, by calculating a distance between the facing edge portions. The camera may be moved relative to the screen to measure slot thickness at several sample locations along a length of the screen. The screen may also be rotated relative to the camera to measure slot thickness at sample locations at different angula r offset locations around the screen. Slot thickness measured at the sample locations may be analyzed to generate an inspection report that could be supplied to a customer with the well screen.
