Suspension stabilizer for preventing abnormal high-temperature thickening of well cementation cement and preparation method of suspension stabilizer
The invention discloses a suspension stabilizer for preventing abnormal high-temperature thickening of well cementation cement and a preparation method of the suspension stabilizer. The suspension stabilizer comprises 65-80 parts of a high-temperature suspension stabilizing main agent, 10-20 parts of a high-temperature suspending agent, 5-15 parts of a high-temperature thickening agent and 1-3 parts of an abnormal high-temperature thickening agent, the high-temperature suspension stabilizing main agent is a water-soluble hydrophobic associated polymer and is obtained through a free radical micelle polymerization reaction. Compared with a common suspension stabilizer, the prepared suspension stabilizer is not obvious in thickening effect at normal temperature and has a good suspension stabilizing effect; at a high temperature, the hydrophobic association effect of the water-soluble hydrophobic association polymer is rapid, and good suspension stability can still be maintained, so that the high-temperature working performance of the high-density well cementation cement slurry for deep wells and ultra-deep wells is effectively guaranteed, the well cementation quality of the deep wells and the ultra-deep wells is improved, and efficient and safe exploitation of oil and gas resources of the deep wells and the ultra-deep wells is guaranteed.
本发明公开了一种防固井水泥高温稠化异常的悬浮稳定剂及其制备方法，所述悬浮稳定剂包括65～80份高温悬浮稳定主剂、10～20份高温悬浮剂、5～15份高温增稠剂和1～3份防高温稠化异常剂；所述高温悬浮稳定主剂为水溶性疏水缔合聚合物，通过自由基胶束聚合反应得到。相较于普通悬浮稳定剂而言，本发明制备的悬浮稳定剂，在常温下增稠效果不明显，且具有良好的悬浮稳定作用；在高温下，由于水溶性疏水缔合聚合物的疏水缔合作用急剧，仍能保持良好的悬浮稳定性能，进而有效保障深井及超深井高密度固井水泥浆的高温工作性能，提高深井及超深井的固井质量，保障深井及超深井油气资源的高效安全开采。
