METHODS AND APPARATUS FOR DETERMINATION OF PARAMETERS RELATED TO A COILED TUBING STRING
摘要
Systems and techniques for non-contact measurement of coiled tubing motion are disclosed. In one embodiment, a system includes a laser source and a laser motion sensor. The laser source is configured to provide laser light that illuminates the coiled tubing as the tubing moves. The laser motion sensor is configured to collect and process laser speckle images and compute measurements of coiled tubing movement based on the laser speckle images.
