The invention relates to a deep high-temperature-resistant salt-resistant fluid loss agent and a preparation method and application thereof. The fluid loss agent suitable for deep high temperature resistance and salt resistance is prepared from the following components in parts by weight: 100 parts of water, 10 to 70 parts of 2-acrylamido-2-methylpropanesulfonic acid, 5 to 80 parts of N, N-dimethylacrylamide, 0.5 to 20 parts of acrylamide, 0.1 to 25 parts of vinylpyrrolidone, 1 to 30 parts of 3-allyloxy-2-hydroxy-1-propanesulfonic acid, 1 to 20 parts of acrylic acid and 0.01 to 20 parts of acrylonitrile. The preparation method of the deep high-temperature-resistant salt-resistant fluid loss agent is simple, and the prepared product has better water solubility and can be matched with other oil well cement admixtures for use at the temperature of less than 180 DEG C. The temperature application range is wide, the salt-resistant effect is good, and the performance of the cement paste is not affected in saturated or semi-saturated salt water.
本发明涉及一种适用于深层抗高温抗盐降失水剂及其制法和应用。所述适用于深层抗高温抗盐降失水剂，包含重量份数计的以下组分：水，100份，2‑丙烯酰胺基‑2‑甲基丙磺酸，10‑70份，N,N‑二甲基丙烯酰胺，5‑80份，丙烯酰胺，0.5‑20份，乙烯吡咯烷酮，0.1‑25份，3‑烯丙氧基‑2‑羟基‑1‑丙磺酸，1‑30份，丙烯酸，1‑20份，丙烯腈，0.01‑20份。本发明所述的深层抗高温抗盐降失水剂的制备方法简单，制得的产品为水溶性较好，可在小于180℃条件下与其他油井水泥外加剂配合使用。具有较宽的温度适用范围及良好的抗盐效果，在饱和或者半饱和盐水中不影响水泥浆的性能。
