NON TOXIC, BIODEGRADABLE WELL FLUIDS |
摘要 |
Well fluids such as drilling muds, especially useful in offshore drilling, are formulated with a hydrocarbon oil blend of a low viscosity poly alpha-olefin (PAO) such as a low molecular weight oligomer of decene together with a C12 to C18 paraffinic hydrocarbon of petroleum origin and a C10 to C18 olefin such as dodecene-1 or tetradecene-1. The fluids exhibit good biodegradability and are non-toxic to marine organisms; they also meet viscosity and pour points specifications for formulation into oil based muds.
