Abstract: On the basis of the theoretical research on the quantitative matching relationship between surfactants and low acid value crude oil, the alkyl benzene sulfonates surfactants have been developed suitable for oil displacement in Daqing Oilfield by using heavy alkyl benzene as raw material, and created the analysis method for heavy alkyl benzene raw materials and products, refining processing techniques, special sulfonated technology for wide-fraction alkyl benzene raw materials, and the integrated technology for neutralization and combination, the new surfactant has realized the large-scale production. The result of field application showed that the properties of the product are the same as those of foreign products, its recovery rate was 20% higher than that of water drive oil method,which promoted the development of ASP flooding in Daqing Oilfield, and improved the core competitiveness of CNPC on tertiary oil recovery.
