| titleOfInvention | Anti-collapse foam liquid and preparation method thereof |
| abstract | The invention provides an anti-collapse foam liquid, which comprises the following components: 0.2-0.4 wt% of a foaming agent; 0.3-0.7 wt% of a borehole wall stabilizer; the borehole wall stabilizer is obtained by copolymerizing acrylic acid, an organic amide monomer and a third monomer, wherein the third monomer is dimethyl diallyl ammonium chloride or allyl trimethyl ammonium chloride; 0.03-0.07 wt% of coating flocculant; the coating flocculant is obtained by copolymerizing acrylic acid, an organic amide monomer and a fourth monomer, wherein the fourth monomer is methacryloyloxyethyl trimethyl ammonium chloride, acryloyloxyethyl trimethyl ammonium chloride, dimethylaminoethyl acrylate or dimethylaminoethyl methacrylate; the balance being water. Under the combined action of all the components of the anti-collapse foam liquid, the anti-collapse foam liquid has strong inhibition, strong adsorption and strong coating and film-forming properties. |
