Research Progress,Current Situation Analysis and Development Suggestions of Drilling Fluid Treatment Agents in China
摘要
Abstract
To understand the new achievements of drilling fluid additives in China,this article reviews the recent development and application of drilling fluid additives,based on modified biomass materials,synthetic polymers,condensation reaction products,modified industrial by-products,and domestic waste modification products.Modified biomass materials,containing starch,cellulose,lignin,and humic acid,are mainly used for fluid loss reducers,and starch is the most common one;the most studied synthetic polymer materials are water-soluble polymers for fluid loss reducers,viscosity enhancers,encapsulating agents,and viscosity reducers.There are also some studies on water-insoluble materials used for plugging and fluid loss reducers.Monomers with good hydrolytic stability such as NVP as well as DMAM are used to enhance temperature-resistant,salt-resistant,and high valent ion-resistant ability.Condensation reaction products focus on emulsifiers and viscosity enhancers of oil-based drilling fluid,and esterification and amidation reaction of lubricants in water-based drilling fluid as well.Some research has also been conducted on the preparation of drilling fluid treatment agents using industrial by-products and household waste.Although there has already been a large number of research on drilling fluid additives,the research is still not innovative,in-depth,and comprehensive enough.Due to the limitations of molecular design,synthetic means,and evaluation methods,there are relatively few drilling fluid additives that can meet the needs of complex fields on site.There is still a phenomenon of similar or low-level repetitive research.Combining with practice.The research on treatment agents should aim to break through traditional thinking and mechanisms.Around the goals of simplifying drilling fluid components,reducing drilling fluid costs,improving drilling fluid functions,enhancing drilling fluid quality,and promoting green development.Strengthen the development and utilization of biomass resources,innovate synthesis methods and processes,and develop low-cost,high-quality,and long-term multifunctional materials with good comprehensive performance.关键词
