▎ 摘　　要

NOVELTY - Production of thermally induced graphene sensing circuitry involves preparing (102) a surface of a component for placement of a coating on the surface, coating (104) a portion(s) (b1) of the surface of the component using a polymer (p1) or a polymer-rich composite, applying a thermal scan for generating (106) a graphene-rich pattern on the portion(s) of the surface of the polymer (p1) or the polymer rich composite, coating (108) a portion(s) (b2) of the surface of the component using a polymer (p2) or a polymer-rich composite, and optionally repeating all the processes. USE - Production of thermally induced graphene sensing circuitry on component e.g. oilfield service component such as valve, packer, casing, and pipe of drill string, test string, and completion string (all claimed). Can also be used for casing drilling, cementing plug, cable protector, float equipment, centralizer, casing shoes, stop collar, nuclear tool, pressure-reading equipment, oil-gas analyzer, and wireline equipment. ADVANTAGE - The method provides high technology-based offerings that are suitable for downhole environments, without major redesign iterations. The offerings are simple, scalable, robust and that will not induce new forms of failure critical to the basic functions of the tools. The methodologies provide for ease of manufacturing as well as cost effective manufacturing. The methods and tools look to reduce maintenance costs, maximize operational reliability and create differentiation between competing technologies.
