    摘要： The present invention provides improved methods for cementing. The methods are basically comprised of the steps of preparing a cement composition comprised of hydraulic cement, water, gas, surfactants, a cement early strength accelerator and a mildly set retarding cement dispersing agent, placing the cement composition in the annulus between the casing string and the well bore and allowing the cement composition to set into a hard impermeable mass. The cement composition used can alternatively comprise hydraulic cement, a water reducing additive, a dispersing additive, a set accelerating additive and water. Also, the cement composition can be made environmentally benign by using water reducing and dispersing additives, set retarding additives, and compressive strength and set accelerating additives which are environmentally degradable.

    摘要翻译： 本发明提供了改进的固井方法。 该方法基本上包括以下步骤：制备由水硬性水泥，水，气体，表面活性剂，水泥早期强度促进剂和温和凝固阻滞水泥分散剂组成的水泥组合物，将水泥组合物置于套管柱和 井眼，并允许水泥组合物成为不透水的块。 所使用的水泥组合物可以替代地包括水硬性水泥，减水添加剂，分散添加剂，集合加速添加剂和水。 此外，水泥组合物可以通过使用减水分散添加剂，凝结阻燃添加剂和抗压强度以及环境可降解的加速添加剂来使环境友好。
