发明名称 PHOSPHOLIPID LUBRICATING AGENTS IN AQUEOUS BASED DRILLING FLUIDS.
摘要 <p>A method of improving the lubricity of an aqueous based drilling fluid composed of an aqueous base fluid, and a weighting agent. The method involves the addition of an effective amount of a phospholipid to substantially reduce the coefficient of friction when compared to the fluid absent the phospholipids. Preferably the phospholipids have the structure: (I), in which R and R' are C6 to C25 hydrocarbon groups; and A is an anion to counter the cationic charge.</p>
