摘要
DSH低摩阻水泥外加剂由减阻剂、降滤失剂、稳定剂及促凝剂复配而成。对加入DSH的水泥浆的流变性能、沉降稳定性、抗压强度、减阻性能、抗窜性能及水泥石的动态性能进行了试验。结果表明,DSH低摩阻水泥外加剂有较强的控制水泥浆滤失能力和减阻作用;DSH水泥浆具有良好的流变性和较低的临界排量,用于小眼井施工可以实现紊流顶替;DSH使水泥石具有良好的动态性能,提高小眼井采油寿命。
DSH cement additive with low frictional re-sistance developed is prepared from drag reducer, filtration-reducing agent, stabilizing agent and accelerating agent. Tests indicate that cement slurry containing DSH possesses the advantage of drag reducing property, filtration reducing property and good rheo-logical property. The compressive strength and gas channeling resistance of cement slurry with DSH are also improved. It is shown that DSH cement additive can satisfy the demand of cementing operation in slim hole.
