Abstract

Abstract:

The aim of this work was to systematically explore the relationship between the structure of extended surfactants and their abilities in reducing interfacial tension （IFT） under seawater conditions. Those extended surfactants with different structures were selected to test IFT. The effects of hydrophobic alkyl chain length, alkyl branching, and numbers of oxypropylene （PO） and oxyethylene （EO） groups on the ability of reducing IFT were investigated. The results showed that by increasing the length of the alkyl chain and the branching of the hydrophobic group, the effectiveness in reduction of IFT was small, which could not achieve the ultra-low level （<10^-2 mN/m）. In contrast, the PO number was a key factor affecting the IFTs of the extended surfactant solutions against hydrocarbons and crude oil. The IFT could be reduced to the magnitude order of 10^-3 mN/m at appropriate hydrophilic-lipophilic balance by spirally curling the long PO segment and thus increasing the hydrophobic group size. The increase of EO groups lead to incompact arrangement of molecules at the interface, resulting in the increase of IFT. The competitive adsorption of crude oil components at the interface was unfavorable to the decrease of interfacial tension. The increase of PO number lead to the gradual decrease of IFT against crude oil. This extended surfactant showed high interfacial activity under seawater conditions, which was suitable for chemical flooding to enhance oil recovery in offshore reservoirs.
