摘要：
Improved compounds and methods for applications in the oil and gas industry are obtained by the disclosed compositions of phosphate salts. These salts have characteristics beneficial to the oil and gas industry for completion fluids, killing fluids, work-over fluids, drilling fluids and packer fluids. These features include high density (up to SG 2.50), low corrosiveness, stability, not subject to disturbance from formation reaction, not prone to precipitate, environmentally sound, capable of buffering pH, and the disclosed formulation is easy to mix in the field with the capability of increasing the density of existing completion fluids used.
