Foaming agent composition for oil field well cementation, foamed cement paste and preparation method of foamed cement paste
The invention relates to the technical field of foamed cement paste, in particular to a foaming agent composition for oil field well cementation and a preparation method thereof, and further discloses foamed cement paste and a preparation method thereof. The foaming agent composition is composed of alkyl diphenyl ether disulfonate, alkyl glycoside, cocamidopropyl betaine, alkylolamide, octylphenol polyoxyethylene ether and water, and has the characteristics of good water solubility, good compatibility, dense and lasting generated foam, low interfacial tension, high foaming amount and long half-life period, and meanwhile, the foaming agent composition can be used for well cementation in oil fields. Foamed cement paste prepared by taking the foaming agent composition for well cementation in the oil field as a raw material is adjustable in density, the strength of foamed cement coagulum is not reduced, the permeability of set cement is effectively reduced, the compactness of the set cement is improved, and the cementing construction requirement can be met.
本发明涉及泡沫水泥浆技术领域,是一种油田固井用发泡剂组合物及其制备方法,还包括一种泡沫水泥浆及其制备方法。前者原料由烷基二苯醚双磺酸盐、烷基糖苷、椰子油酰胺丙基甜菜碱、烷基醇酰胺、辛基酚聚氧乙烯醚和水组成,本发明油田固井用发泡剂组合物具有水溶性好,配伍性佳,产生的泡沫绵密持久,低界面张力,高发泡量,长半衰期的特点,同时,以本发明油田固井用发泡剂组合物为原料制备的泡沫水泥浆,其密度可调,且泡沫水泥凝结物强度不下降,有效降低水泥石渗透率,改善水泥石致密性,可满足注水泥施工要求。
