| Currently, a study on the block as a whole has entered a high water content and a high degree of recovery during the mining, polyethylene table agent became a late high water cut, effective way to improve the recovery of sub-layers. Studies have been carried out in a block of a plurality of sub-layers and polymer flooding after polymer block table agent flooding pilot test, after the effective recovery well liquid production dropped significantly, the decrease in water content is large, the produced fluids see to emulsification, effective control of the water rising speed, recovery is greatly improved. This paper mainly polyethylene sheet analysis and application status of agent mechanism analysis, produced liquid form and formation factors analysis, technical research of oil displacement agent polyethylene sheet, polyethylene sheet breaking research techniques agent emulsion flooding, drawn four poly table agent emulsion stabilizing capacity of the order: type â…¡> â…¢(O / W) type> â…¢(W / O) type> type â… ; table molecules adsorbed poly use its amphiphilic nature of the oil-water interface, the formation strength high, closely spaced bilayer interfacial film, so the stability of the emulsion increases conclusions such as, preferably a P2, SP1 for the two kinds of block development demulsifier, was to increase the recovery of demulsification. |
