摘要：
A mobile apparatus and method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oleaginous component and an aqueous component. The apparatus includes an emulsion breaking tank, a water treatment tank, a filter press, and hydrocarbon filters. The method includes: mixing said invert emulsion drilling fluid with a emulsion breaker, wherein the emulsion breaker is a mixture of an alkyl glucoside and an alkane sulfonate; and separating the oleaginous component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaker that is a combination of an anionic surfactant, a nonionic surfactant and an alkyl polyglycoside surfactant.
