Abstract

The invention discloses a preparation method of a viscosity reducer for ultra-viscous oil pipeline transportation and belongs to the technical field of petrochemical engineering. The preparation method comprises the steps that lard oil and the like are heated and melted at first and then are subjected to still standing and mildewing; grown mold is inoculated into a prepared crude oil culture medium to be cultured; the mold in obtained hypha suspension liquid is ruptured through lysozyme, then cytoplasm is released, and mixed enzyme powder is prepared after drying; and then used oil is degraded into base oil through microorganisms in activated sludge of a secondary sedimentation tank, the base oil, the mixed enzyme powder and the like are uniformly mixed, and thus the viscosity reducer for ultra-viscous oil pipeline transportation is obtained. According to the preparation method of the viscosity reducer for ultra-viscous oil pipeline transportation, cell incision enzyme and excision enzyme in the cultured mold are utilized, in the ultra-viscous oil transportation process, energy is produced, and the affinity of colloid, asphaltene or wax molecules in ultra-viscous oil is changed, so that a carbon long chain of the ultra-viscous oil is ruptured; meanwhile, a large number of free radicals and dissociative radicals are produced and are diffused into crude oil; the alkane compositional ratio of the crude oil is increased; the freezing point and the viscosity of the crude oil are reduced; and the problem that a traditional viscosity reducer is poor in viscosity reducing effect is effectively solved.

Description

technical field [0001] The invention discloses a preparation method of a viscosity reducer for pipeline transportation of super heavy oil, belonging to the technical field of petrochemical industry. Background technique [0002] High density, high freezing point, high viscosity, and difficult flow are the outstanding characteristics of heavy oil resources, which seriously restrict the exploitation and transportation of heavy oil. For a long time, for the transportation of high-viscosity and high-condensation crude oil, traditional heating and emulsification methods have been mainly used at home and abroad. The former is intermittent heating along the oil pipeline, which consumes a lot of fuel and power; Deal with (such as dehydration) problems. These two methods are still the main methods for dealing with high-condensation and high-viscosity crude oil transportation. However, at present, the most common concern of domestic and foreign petroleum industries is to use chemica...
