Foam stabilizer composition, foamed cement slurry and additive composition thereof
The present invention relates to the field of oil and natural gas well cementation engineering, in particular to a foam stabilizer composition, foamed cement slurry and an additive composition thereof. The foam stabilizer composition comprises C6-C20 alkyl amido alkyl amine oxide, C6-C20 alkyl amido alkyl betaine, and triterpenoid saponin compound. The foam stabilizer composition provided in the present invention is helpful for forming foamed cement slurry that has high foam stability, and the foam stabilizer composition can work with other active components in the foamed slurry additive composition provided in the present invention to enable the foamed cement slurry that contains the additive composition to obtain low density, high foam stability, low permeability, and high compressive strength, which is especially applicable to well cementing operation in an oil and natural gas exploration and development process.
