Polymer Oil-displacing Agent Polyacrylamide For Oil Field Chemicals
Description:
Based on the relationship between the molecule structure of monomers and their performance, two types of polymerizable monomers with low oil/water interfacial tension have been synthesized, which coplymerizes acrylamide to synthesize a novel polymer oil displacement agent under compound initiator and low polymeric temperature. Its structure and distribution status in brine solution were characterized by infrared spectroscopy and freeze etching electron microscope. The results show that the polymer has good water solubility, viscosifying properties, salt-resistance and temperature-tolerance, shearing-resistance in brines. Due to the graft polymerization of acrylamide and the polymerizable surface-active monomers, the polymer overcomes chromatographic separation effect, and has low oil/water interfacial tension. Interfacial tension of 0.15% polymer solution (prepared in Daqing simulation brine) is around 10−1 mN/m in Daqing No.1 oil plant crude oil. Core flooding experiments show that the oil recovery of the novel surface active polymer is 5.2% higher than that of ordinary hydrolyzed polyacrylamide because of its better viscosifying performance and lower oil/water interfacial tension.
Polymer flooding is achieved by adding a certain amount of high molecular weight polyacrylamide to the injected water to increase the viscosity of the injected water, improve the oil-water current ratio,adjυst the water injection profile, expand the swept volume. Since the viscoelasticity of the polymer molecule has a stretching and carrying effect. on the oil film oil droplets, the oil displacement efficiency is improved and the oil recovery efficiency is improved.
Oil displacing agent of oil field tertiary oil recovery:It can adjust the rheology of filled water, increase the
viscosity of driving liquid, improve water drive wave and efficiency, lower water phase permeability in ground
layer, and enable water and oil to flow forward at even speed. Its effect is that it is mainly used in tertiary oil
recovery of oil fields in the aspect oil production, and raw oil of about 100 to 150ton more can be produced
through filling the macromolecule polyacrylamide product one ton.
Well drilling mud raw materials:in oil field exploration and development and exploration of geology, water and
coal, it is used as adhesive of well drilling mud raw materials, can improve the service life of drill bits, improve
the drill speed and drilling footage, and reduce plug in replacing drill, and has prominent well slough
preventing effect, and it can be used as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.
