oil and other additives synergist

Enhanced oil recovery using a drive fluid to the surfactant as the main additive, but also need small amounts of other additives, such as builders? Soluble polymer? Food dehydrator Electrolytes and sacrifice agent. 2 .. 2.1 synergist Its role is to make use of the surfactant in the lack of performance, such as increased solubility, inhibit surfactant such as oxidation and hydrolysis. I onic surface active agents with the microemulsion, it is usually to add a co-surfactant. Often as synergist with the main types of surfactant (different structure or ionic) surfactants (the same amount of surfactant for much less than), and a polar organic medium chain parents such as alcohol? sour? phenol? ketone? amines? sulfone, etc., and some even add plasticizers? superplastic agent? lipid fatty acid soaps, of which the most commonly used alcohol, the most studied. 2.2.2 The oil equipment polymer which is used as a thickener to control flooding fluid viscosity and improve Flooding plugging efficiency. Polyacrylamide and are commonly used with other organic materials such as acrylamide and vinylpyrrolidone? Methacrylic acid copolymer. 2.2.3 JianJian can significantly reduce surfactant flooding during the adsorption and precipitation, and the acid can remove the oil, the surface active agent to increase oil interfacial activity. Commonly used NaOH? Na2CO3? NaHCO3? Or Na2SiO3 and so on. 2.2.4 electrolyte is added to the electrolyte is not miscible with the oil to form an oil phase? Aqueous phase and three-phase microemulsion system for separation. 2.2.5 sacrificial agent in order to avoid the surfactant enhanced oil recovery process of being adsorbed formation, adding a surfactant Flooding formal adding inexpensive sacrificial effect from a surface active agent, so that the formation of the first adsorbed to reduce official loss of surfactant. Such as lignin can be added and modified products? Oil carboxylate salt.
