By summarizing the composition, classification, and performance characterization of functional adhesive materials, the adhesion mechanisms of functional adhesive materials, such as adsorption/surface reaction, diffusion, mechanical interlocking, and electrostatic adsorption, are expounded. The research status of these materials in oil and gas drilling and production engineering field such as lost circulation prevention/control, wellbore stabilization, hydraulic fracturing, and profile control and water plugging, and their application challenges and prospects in oil and gas drilling and production are introduced comprehensively. According to the applications of functional adhesive materials in the field of oil and gas drilling and production at this stage, the key research directions of functional adhesive materials in the area of oil and gas drilling and production are proposed: (1) blending and modifying thermoplastic resins or designing curable thermoplastic resins to improve the bonding performance and pressure bearing capacity of adhesive lost circulation materials; (2) introducing low-cost adhesive groups and positive charge structures into polymers to reduce the cost of wellbore strengthening agents and improve their adhesion performance on the wellbore; (3)introducing thermally reversible covalent bond into thermosetting resin to prevent backflow of proppant and improve the compressive strength of adhesive proppant; (4) introducing thermally reversible covalent bonds into thermoplastic polymers to improve the temperature resistance, salt-resistance and water shutoff performance of adhesive water shutoff agents.
