Geopolymer for well cementation based on reactive activator
The invention belongs to the technical field of well cementation, and particularly relates to a geopolymer for well cementation based on a reactive activator, the geopolymer is prepared from the following raw materials in parts by weight: 100 parts of a cementing material, 20-31 parts of an activator, 0.2-5 parts of a retarder and 50-60 parts of water, the activator is a mixture of modified sodium oxalate and calcium hydroxide, and the weight ratio of the modified sodium oxalate to the calcium hydroxide is (13-20): (7-11); according to the invention, modified sodium oxalate and calcium hydroxide are used as activators instead of sodium hydroxide, and a retarder is combined to regulate and control the thickening time of the geopolymer; the geopolymer is simple in formula, compared with the prior art, the strength performance of the prepared geopolymer is greatly improved, and the problems that the thickening time of the geopolymer is difficult to regulate and control, the strength is not high and the formula is complex are solved.
本发明属于固井技术领域，具体涉及一种基于反应型激活剂的固井用地质聚合物，以重量份计，其原料组成为：胶凝材料100份，激活剂20～31份，缓凝剂0.2～5份，水50～60份，所述的激活剂为改性草酸钠和氢氧化钙的混合物，以重量比计，改性草酸钠：氢氧化钙＝13～20：7～11；本发明采用改性草酸钠与氢氧化钙替代氢氧化钠做激活剂，并结合缓凝剂来实现地质聚合物稠化时间的调控；本发明所述的地质聚合物配方简单，与现有技术相比，制得的地质聚合物强度性能有较大的改善，解决了地质聚合物稠化时间难调控、强度不高、配方复杂的难题。
