摘要： A water based drilling fluid comprises :
(a) an aqueous medium, (b) a polyalkylene glycol of general formula :
wherein R is H or CH 3 , R 1 is H or an alkyl group containing 1 to 4 carbon atoms, and n is a number in the range 4 to 200, and (c) a potassium salt. In the case of tetra- and higher molecular weight polyalkylene glycols, there is a synergistic clay-stablising effect between these compounds and the potassium salt.

摘要： The present invention relates to a process and a device for introducing a catalytically active powder into a reactor (20) for gas phase alpha-olefin polymerization. The device comprises a storage vessel (3) containing the powder, a metering valve (4) delivering metered quantities of the powder into an intermediate chamber (5) comprising at least one obstacle (6) separating an upper part (5a) of the chamber (5) comprising an auxiliary gas inlet (2a) from a lower part (5b) terminated by an outlet orifice (5c). A connecting pipe (18) connects the outlet orifice (5c) to a mixing device (8) situated on a conveying pipework (15) communicating with the reactor (20). The powder is introduced into the reactor in a dilute suspension form and in a more uniform rate.

摘要： A method for recovering the surfactant from a dispersion or emulsion of oil and water containing a temperature sensitive surfactant which method comprises the steps of heating the dispersion or emulsion to a temperature above the cloud point of the surfactant under conditions of temperature and aqueous phase salinity such that the dispersion or emulsion breaks and separates into an oil layer, an aqueous layer and a surfactant layer, and recovering the surfactant layer.
The recovered surfactant may be recycled for use in preparing further quantities of dispersion or emulsion, thus rendering the operation more economic.

摘要： Water soluble polymers from acrylic acid optionally with other monomers have a narrow molecular weight distribution and are made by continuous loop polymerisation particular in the presence of sodium chlorate and sodium metabisulphite as redox initiator. The loop polymerisation gives more uniform product than batch operation and the narrow molecular weight distribution gives polyacrylates useful in water treatment, scale inhibition and as dispersants.

摘要： An oil field production chemical, especially a scale inhibitor, is in the form of particles thereof carrying a coating e.g. of a dispersing agent. The coating may be polymeric such as an oligomeric polyacid polyester, a polymeric alkoxylated alcohol or a fatty acid polyamine condensate or it may also be a surfactant and may be used in the form of a suspension in an inert oil, such as diesel oil or kerosene which may be injected into a subterranean formation to inhibit the formation of deposits, e.g. scale in oil wells over a longer period than compounds free of the coating.
