摘要

To solve the problem of strong stabile polymer sludge produced that is difficult to deal with in Shengli oil field, the scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) were selected to analyze the construction of the polymer sludge and the influence of the surfactants affect on it. The results show that the main reason that causes the strong stability of polymer sludge is the network precipitate made by the hydrolyzed polyacryamide (I-IPAM) and polyaluminium chloride (PAC), while the network precipitate is connected by the chemical bonds of Al-O and N+-CI. The non-ionic detergent EL100 could effectively break the chemical bonds of Al-O and, make the element N occurred in the form of N-(CH3)(3), and then break the network structure, thus decrease the stability of polymer sludge; the anionic detergent sodium alcohol ether sulphate (AES) could not break the chemical bonds and decrease the content of N-(CH3)(3) construction, thus increase the stability of polymer sludge slightly. The cationic detergent CTMB could remarkably decrease the content of N-(CH3)(3) construction, and make the element N occurred in the form of N+-C bond, which will remarkably increase the stability of polymer sludge.
