Influence of Scaling in Alkaline/Surfactant/Polymer Flooding Surface Process

Abstract:

With the Alkaline-surfactant-polymer (ASP) flooding production processs developing, deposition and scaling problems are serious in ground watering and gathering system, pronounced at watering pipeline and heating furnace. So challenges must be faced with in oilfield development process, such as energy consumption increase, equipments and pipelines are damaged easily, and equipments service life shortens. The component of scale sample, which is took from ASP flooding area of Xingbei Oilfield in Daqing Oilfield, in surface watering system is investigated. The influence factors and regulation of scaling in watering system are studied by simulation experiments. It turned out that the scale sample is consists of silica scale, carbonate scale, corrosion scale and organic substance, and the silica scale is the main scale, which content is more than 45%. The watering temperature, flow rate and polymer concentration are main factors of influencing scaling in watering system. Under the conditions of ASP flooding normal production, the effect of polymer concentration is prominent.
