This paper studies the properties of Silicate and Silicate drilling fluids, compares the anticollapse capability of different inorganic salt inhibitors and analyzes the influences of every components on the properties of Silicate drilling fluids. The results show that the anticollapse capability of silicate is better than other inorganic salts with the same concentration. A mixture of silicate and other anticollapse inhibitors can improve anticollapse capability of drilling fluids and pH is a key factor influencing the anticollapse capability of silicate.
