Application of polyacrylic resin in self-repairing agent for gas well cementation, self-repairing agent, preparation method of self-repairing agent, cement composition and cement paste
The invention relates to an application of polyacrylic resin in a self-repairing agent for gas well cementation, the self-repairing agent, a preparation method of the self-repairing agent, a cement composition and cement paste, and belongs to the field of petroleum engineering gas well cementation. According to the application of the polyacrylic resin with the structural unit represented by the formula I in the self-repairing agent for gas well cementation, the polyacrylic resin with the structural unit represented by the formula I can be used for solvation with hydrocarbon molecules in the hydrocarbon environment and macromolecular chains of the polyacrylic resin after set cement formed by cement paste hardening cracks, so that the hydrocarbon molecules enter the polyacrylic resin to cause extension of a three-dimensional molecular network, the volume of the polyacrylic resin is expanded, and self-repairing of micro-cracks generated in set cement and micro-annular gaps formed by the micro-cracks and the inner wall of a casing pipe is realized.
本发明涉及一种聚丙烯酸树脂在气井固井的自修复剂中的应用、自修复剂及制备方法、水泥组合物、水泥浆，属于石油工程气井固井领域。本发明的具有如式I所示结构单元的聚丙烯酸树脂在气井固井的自修复剂中的应用，利用具有式I所示结构单元的聚丙烯酸树脂能够在水泥浆硬化形成的水泥石产生裂缝后，烃类环境中的烃类分子和聚丙烯酸树脂的高分子链发生溶剂化作用，使烃类分子进入聚丙烯酸树脂内引起三维分子网的伸展，进而使聚丙烯酸树脂体积膨胀，从而实现自我修复水泥石中产生的微裂缝及与套管内壁形成的微环隙。
