Abstract
A polymer silicate drilling fluid is developed for deep water drilling.This fluid has the capacity of inhibiting the formation of gas hydrates.It is stable at elevated temperatures and helps stabilize instable formations.Hot rolling test gives a more than 90%recovery rate.Permeability recovery rate is higher than 90%.Bioassay shows that this fluid meets the discharge requirements imposed national standards.After weighted with weighting agent to high densities,this fluid can be used in deep well drilling.
