摘要： Described is the use of surface-active alpha-sulfofatty acid di-salts as ecologically compatible emulsifiers of the W/O type and O/W type, respectively, in fluid and pumpable drilling fluids and other fluid drilling-hole treatment agents which comprise a continuous or a dispersed oil phase together with an aqueous phase and which are suitable for an environmentally acceptable exploitation of geological resources, for example oil or natural gas deposits. The invention further relates to inverted drilling fluids based on a continuous oil phase and, present therein, a dispersed aqueous phase which, in addition to the emulsifiers, contain further conventional auxiliary agents such as thickeners, fluid-loss additives, weighting agents, water-soluble salts and/or alkali reserves. The inverted drilling fluids according to the invention are characterized in that they contain surface-active di-salts of the type indicated as emulsifier or as an emulsifier component together with an ecologically compatible continuous oil phase.

摘要： Described is the use of oleophilic monomeric and/or oligomeric diesters of carbonic acid with the same or different oil-soluble and ecologically compatible mono-functional and optionally polyfunctional alcohols as a component of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The invention in one embodiment comprises oil-based fluids, and particularly inverted fluids of the W/O type, which in the continuous phase at least in part contain oleophilic carbonic acid diesters. In a further important embodiment the invention relates to water-based emulsion fluids which in the dispersed oil phase at least in part contain said oleophilic carbonic acid diesters. The invention further comprises drill-hole treatment agents, and especially drilling fluids of the above-mentioned types, the continuous or dispersed oil phases of which, respectively, consist of oleophilic carbonic acid disasters or contain said ester type in admixture with other ecologically compatible oil mixing components. Preferred mixing components for a use in combination which the carbonic acid diesters are appropriate carboxylic acid ester oils, oleophilic alcohols and/or oleophilic ethers.

摘要： The composition of matter and application thereof in the present invention relates to the application of a synthetic hydrocarbon compound, a polyalphaolefin liquid, blended in various concentrations with chemical oil and water emulsifiers, thinners and oil and water surface tension reducers, the concentration of polyalphaolefin liquid to that of the remaining portion of the blend being no less than 5%; blending the polyalphaolefin liquid and the emulsifiers in a blending tank containing water base drilling mud; circulating the blend of polyalphaolefin liquid and emulsifier with the water base drilling mud down hole, so that the blend of polyalphaolefin liquid emulsifier and water base drilling mud lubricates the drill string or reduces the differential pressure between the wall of the borehole and the drill string so that the drill string is free to rotate and drilling may be undertaken with less drag or torque. In another application, the polyalphaolefin blended with the emulsifier serves as a spotting fluid in order to unstick drill pipe that has become stuck.

摘要： A self-breaking, foamed, oil-in-water emulsion contains a water-immiscible organic solvent for paraffins and asphaltenes, an aqueous nonformation-damaging component, an inert gas, and surface active agents selected to promote a stable foamed emulsion despite contact of the treating fluid with the hydrocarbon and aqueous environment in the reservoir. Under conditions of agitation, the treating fluid is a stable foamed emulsion which undergoes spontaneous breakdown into two liquid phases under quiescent conditions. The treating fluid is injected and/or circulated as a stable foamed emulsion to dissolve paraffin and asphaltene-containing deposits from various substrata, such as a subterranean reservoir penetrated by a well, the well itself, or an industrial vessel or conduit. When injection or circulation is stopped, the foamed emulsion spontaneously breaks down so that the treating fluid can be readily pumped from the well.
