摘要
Alkylbenzene sulfonate is added to a crude oil sulfonation product to prevent the formation of insoluble precipitates in the crude oil sulfonation product. The use of an alkylbenzene sulfonate as an additive to a microemulsion slug containing crude oil sulfonation product improves the injectivity of the microemulsion slug and prevents substantial plugging of the fluid injection system and the subterranean oil-bearing formation by insoluble precipitates in the microemulsion.
