Cement additive, cement composition and cement paste
The invention relates to a cement additive, a cement composition and cement paste, and belongs to the technical field of oil well cementation. The cement additive mainly comprises an elastic-plastic toughening agent, a fluid loss agent, an expanding agent, an anti-channeling agent and a drag reducer, the mass ratio of the elastic-plastic toughening agent to the fluid loss agent to the expanding agent to the anti-channeling agent to the drag reducer is (2.1-2.8): (1.8-3): (0.8-1.2): (2.5-3.5): (0.1-0.3). When being used for preparing set cement, the cement additive has the advantages of low cost, high strength, high elasticity and high toughness, and can meet the requirements of slim-hole well cementation.
本发明涉及一种水泥添加剂、水泥组合物和水泥浆，属于油井固井技术领域。本发明的水泥添加剂主要由弹塑增韧剂、降失水剂、膨胀剂、防窜剂和减阻剂组成；所述弹塑增韧剂、降失水剂、膨胀剂、防窜剂和减阻剂的质量比为2.1～2.8:1.8～3:0.8～1.2:2.5～3.5:0.1～0.3。本发明的水泥添加剂，用于制备水泥石时，同时具有低成本、高强度、高弹性和高韧性的优点，可满足小井眼固井的要求。
