Systems and methods for collecting cutting samples during oil and gas drilling operations

摘要

A system for automated collection of cutting samples produced during the drilling of a well includes a venturi-effect extractor, which receives a flow of carrier fluid, input fluid containing cuttings in response to suction generated by the flow of the carrier fluid, and output the carrier fluid and the fluid containing the cuttings to a packaging system. The packaging system separates the cuttings from carrier fluid and the fluid containing the cuttings, deposits the cuttings at a corresponding point along a moving elongated strip of base material, covers the elongated strip of base material and the cuttings deposited on the base material with an elongated strip of cover material, and advances the covered elongated strip of base material and covered cuttings onto a reel.
