摘要：This chapter evaluates and compares the indoor performance of different concentrations of non gelatinized starch and gelatinized starch in drilling fluid, gelatinized modified starch at 80°C, and then aged at high temperature. Taking the plastic viscosity (PV) and filtration loss (FL) as the main evaluation indexes, a formula with better performance was selected as the main additive and used as the follow-up study. At the same time, the inhibition of gelatinized starch in water-based drilling fluid was investigated.
