Anti-freezing temperature-resistant salt-resistant fluid loss agent and preparation method thereof
The invention relates to an anti-freezing, temperature-resistant and salt-resistant fluid loss agent and a preparation method thereof, and belongs to the technical field of oil field well cementation and cement paste leaking stoppage. The anti-freezing, temperature-resistant and salt-resistant fluid loss agent disclosed by the invention is prepared from the following raw materials in parts by mass: 47 to 75 parts of deionized water, 10 to 15 parts of 2-acrylamide-2-methylpropanesulfonic acid, 2 to 10 parts of acrylamide, 0.1 to 0.5 part of acrylic acid, 6 to 10 parts of liquid caustic soda, 0.01 to 0.02 part of an initiator and 7 to 18 parts of a freezing point lowering agent. The anti-freezing, temperature-resistant and salt-resistant fluid loss agent disclosed by the invention still has flowability at low temperature and also has the advantages of temperature resistance and salt resistance. The invention also provides a simple and feasible preparation method of the anti-freezing, temperature-resistant and salt-resistant fluid loss agent.
本发明涉及一种抗冻型耐温抗盐降失水剂及其制备方法，属于油田固井及水泥浆堵漏技术领域。本发明所述的抗冻型耐温抗盐降失水剂，包括以下质量份数的原料：去离子水47‑75份，2‑丙烯酰胺‑2‑甲基丙磺酸10‑15份，丙烯酰胺2‑10份，丙烯酸0.1‑0.5份，液碱6‑10份，引发剂0.01‑0.02份，冰点降低剂7‑18份。本发明所述的抗冻型耐温抗盐降失水剂，既在低温下仍具有流动性，又具有耐温抗盐的优点；本发明同时提供了一种简单易行的抗冻型耐温抗盐降失水剂的制备方法。
