Polymer retarder beneficial to cementation of long-sealing well cementation cement sheath and preparation method of polymer retarder
The invention relates to a polymer retarder beneficial to cementation of a long-sealing well cementation cement sheath and a preparation method thereof, the polymer retarder is prepared from the following components: 40 to 85 parts of water, 20 to 30 parts of AMPS, 15 to 25 parts of AA, 2 to 8 parts of long-chain alkyl alcohol polyoxyethylene ether methacrylate, and 2 to 8 parts of gamma-methacryloxypropyltrimethoxysilane. The invention has the beneficial effects that the adhesive strength with the well wall and the casing pipe is effectively improved, the transition time of 40Bc-100Bc is shortened, the cementation quality of a cement sheath interface is improved, and the annular gas channeling prevention effect is achieved.
本发明涉及一种利于长封固固井水泥环胶结的聚合物缓凝剂及其制备方法，该聚合物缓凝剂，由以下组分制备而成：水40‑85份、AMPS 20‑30份、AA 15‑25份、长链烷基醇聚氧乙烯醚甲基丙烯酸酯2‑8份、γ‑甲基丙烯酰氧基丙基三甲氧基硅烷2‑8份；本发明达到的有益效果是：有效提高与井壁和套管的粘接力，缩短40Bc‑100Bc的过渡时间，提高水泥环界面胶结质量，起到环空防气窜的作用。
