Tertiary oil recovery

Tertiary oil recovery (EOR) becomes a in a Food dehydrator secondary recovery after a major EOR technology, and a surfactant in EOR increasingly obvious importance, wherein the surfactant flooding and ASP flooding (ASP, namely alkaline - surfactant - polymer flooding) is the development potential of EOR technologies. This paper describes and summarizes the EOR surfactant preparation? Performance? Application characteristics and development prospects. Contents: 1 Introduction rational exploitation of oil expeller has attracted great attention. As a conventional? Secondary recovery (POR and SOR) total oil rate is not high, generally only 20% to 40%, up to 50%, 50% to 80% of the oil recovery possible. Therefore, the growing tension in the energy case, enhanced oil recovery rate has become a major issue of oil exploration, EOR is a particularly effective method of enhanced oil recovery. Currently, research EOR surfactants and microbial enhanced oil recovery to get people's universal attention, and surfactant flooding is showing obvious advantages, which are used primarily driven fluid additive is a surfactant, surfactant flooding article discusses the Surface surfactant preparation? application characteristics and progress.
