- Abstract
With the gradual expansion of oil and gas exploration and development to the ocean and deeper strata, and the proposal that sulfonated materials be included in the "List of Hazardous Wastes" in China, it has become an urgent task to develop non-sulfonated filtrate reducers with high-temperature resistance for water-based drilling fluid. The research progress of water-based non-sulfonated filtrate reducers for high temperature drilling fluid was summarized by combing the relevant research at home and abroad. Non-sulfonated filtrate reducers were mainly divided into three categories, such as modified natural polymer, synthetic polymer and organic/inorganic composite nano-particle. It covered modified starch, modified humic acid, modified oligosaccharide, synthetic polymer, modified resin, graphene, other nano-material types and so on. The selection of non-sulfonated raw materials, preparation methods, product properties and action mechanism were emphatically reviewed. By comprehensively analyzing the advantages, disadvantages, and adaptability of various non-sulfonated filtrate reducers with high-temperature resistance, future developmental trends were proposed. Building upon a foundation of mastering etherification, esterification, crosslinking, and grafting modifications, the evolution of modified natural polymer filtrate reducers was inevitably heading towards composite modification. This trajectory sought to strike a harmonious balance between their non-toxic, degradable attribute, and temperature resistance capability. Synthetic polymers and organic/inorganic composite nano filtrate reducers exhibited conspicuous advantages in terms of temperature resistance. The pivotal consideration lied in achieving equilibrium between cost and performance. Essential focal point included the selection of non-sulfonated monomers and streamlining the production process.
