Abstract

The invention discloses an emulsion paraffin removing and inhibiting agent and a preparation method thereof, belonging to the technical field of oil exploitation. The emulsion paraffin removing and inhibiting agent comprises, by weight, 20 to 25 parts of polyoxyethylene nonyl phenyl ether, 8 to 13 parts of monoglycerol linoleate, 3 to 5 parts of Bacillus licheniformis, 6 to 9 parts of a methacrylic resin, 10 to 15 parts of triisopropanolamine, 30 to 40 parts of isopropanol, 20 to 40 parts of tert-butyl alcohol, 3 to 8 parts of sodium hexametaphosphate, 6 to 12 parts of lignin quaternary ammonium salt surfactant, 8 to 15 parts of 2,4-di(brominated-3-alkylimidazole)-1,3-propylene glycol, 0.5 to 1 part of a soda effervescent tablet, 5 to 10 parts of agarose and 150 to 200 parts of water. The preparation method is simple; and the prepared emulsion paraffin removing and preventing agent has a good paraffin removing effect, exerts certain oil washing, viscosity reducing and paraffin inhibiting effects and has the characteristics of less combustion and explosion proneness, low toxicity, high efficiency, low cost, etc.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and in particular relates to an emulsion wax remover and anti-wax agent and a preparation method thereof. Background technique [0002] For crude oil with a certain amount of paraffin dissolved in it, during the exploitation process, with the decrease of temperature and pressure and the precipitation of gas, the so-called waxing phenomenon occurs. Wax deposition will block the oil-producing layer, reduce the production of the oil well, and also increase the load of the oil well, causing production accidents. [0003] In the production process of waxy crude oil, although various wax prevention methods can be used, the problem of wax deposition is still unavoidable in oil wells. Wax deposition seriously affects the normal production of oil wells, so measures must be taken to remove it. At present, the wax removal methods commonly used in oil wells include mechanical wax removal, th...
