Temperature-sensitive low-density well cementation cement slurry suspending agent, cement slurry and preparation method of temperature-sensitive low-density well cementation cement slurry suspending agent
The invention discloses a temperature-sensitive low-density well cementation cement slurry suspending agent, cement slurry and a preparation method. The suspending agent is prepared from the following components in parts by weight: 3 to 8 parts of N-vinyl caprolactam, 7 to 12 parts of acrylamide, 20 to 25 parts of 2-acrylamido-2-methylpropanesulfonic acid, 0.2 to 1.0 part of methyl methacrylate and 0.3 to 0.45 part of ammonium persulfate. The temperature-sensitive low-density well cementation cement slurry suspending agent disclosed by the invention can keep the viscosity basically unchanged in a temperature range of 40-160 DEG C, and can effectively avoid the problem of serious suspension instability caused by intensified thermal motion of low-density cement slurry when the temperature is changed; floating of lightening materials and sinking of heavy materials in the low-density cement paste are prevented, and the problem of poor interlayer packing caused by serious bleeding is prevented.
本发明公开了温敏型低密度固井水泥浆悬浮剂、水泥浆及制备方法，悬浮剂包括：以重量份数计的3～8份N‑乙烯基己内酰胺、7～12份丙烯酰胺、20～25份2‑丙烯酰胺基‑2‑甲基丙磺酸、0.2～1.0份甲基丙烯酸甲酯和0.3～0.45份过硫酸铵。本发明的温敏型低密度固井水泥浆悬浮剂可以在40～160℃的温度范围内保持粘度基本不变，该悬浮剂可有效避免温度变化时低密度水泥浆因自身热运动加剧导致的悬浮失稳严重的问题，防止低密度水泥浆中减轻材料的上浮和重质材料的下沉，预防因析水严重而引起的层间封隔不良的问题。
