Study On Preparing For The Petroleum Carboxylate

The Daqing Oil Field has already entered the high containing water time at present through more than40 years development, it is more and more difficult to be dependent on pouring water the extraction. Thatthe, use of chemical agent drives the oil (three extractions) to enhance the recovery ratio of crude oil hasbecome one of the main development research directions. Thus extraction oil rate (EOR) plays more andmore vital role in the sustainable development of oil field. In recent years, it has been studying how to takethe petroleum carboxylate as the surface active agent of EOR. This article introduced the synthesis whichtake the Daqing crude fraction oil as the raw material, and use the liquid-phase oxidation to producepetroleum carboxylate. According to the coordination effect of petroleum carboxylate and alkyl benzenessulfonate, the article studied two kinds of domestic produces surface active agent duplicate to match thesystem and contact surface performances room between in the Daqing crude oil the findings indicated that,this duplicate matched the system to be able to form 10^-3mN/m below with the Daqing crude oil the ultralower bound surface tension. Three Yuan compound systems drive the oil efficiency ratio water drive toenhance abort 20% (OOIP). This achievement application may cause three yuan compound drive cost toreduce above 30%. This research realized the formula experimental domestic product. For vigorouslydevelopment three yuan compound drive establish the good theory and the practice foundation in theDaqing Oil Field. In this article several kinds of solution systems which was prepared under the differentlevel condition has been carried on the system analysis, basically understood the organic matter racecomposition and its distribution of this kind of system, and has estimated the mean molecular weight ofcarrboxylic acid. It is very important to the mechanism reaction of fraction oil gas phase oxidation andcontact surface research of this kind of solution system.
