摘要
By the theoretical analysis and contrast on preparation methods of saltwater drilling fluid, according to the field application with existed salt resistant materials and based on the analysis and the tests on influence mechanism of pre-hydration to drilling fluid properties and influence of pre-hydration time to drilling fluid properties, the authors point out that the pre-hydration is very important to the performance of drilling fluid. The analysis provides practical guide and theoretical basis to preparation of different drilling fluids with different emphasis points.
