Research Progress and Trend in High-Performance Water-Based Drilling Fluid Additives
Drilling fluid is called the blood of oil drilling engineering,which plays an important role in cleaning borehole,protecting drilling tool,stabilizing borehole wall and balancing formation pressure.This paper provides a review of the research progress in high-performance drilling fluid additives,including high-performance inhibitors,lubricants,encapsulators,and filtration reducers.The four categories of additives encompass the latest achievements from both domestic and international researchers,as well as mature products that have been successfully implemented on-site by foreign oilfield service companies and chemical companies.Based on the research and application of high-performance water-based drilling fluid additives,the future development trend was described.
