Micro-thixotropic anti-channeling cement slurry system
The invention discloses a micro-thixotropic anti-channeling cement slurry system, which comprises well cementation cement, water and a lightening material, the lightening material is a floating ball particle, the floating ball particle takes a solid glass particle as a core, and the glass particle is coated with a polystyrene layer; the diameter of the glass particles ranges from 0.075 mm to 0.1 mm, the thickness of the polystyrene layer ranges from 0.03 mm to 0.5 mm, the diameter of the formed floating ball particles ranges from 0.135 mm to 0.2 mm, and the density of the formed floating ball particles ranges from 1.03 g/cm < 3 > to 1.1 g/cm < 3 >. The cement paste system is stable in density and strength, the random error between theoretical design and actual construction is small, the actual construction difficulty is reduced, and the overall stability of the engineering quality is improved.
本发明公开了一种微触变防窜水泥浆体系，包括固井水泥、水以及减轻材料，所述减轻材料为浮球颗粒，浮球颗粒以实心玻璃颗粒为核心，玻璃颗粒外包覆聚苯乙烯层；所述玻璃颗粒的直径范围为0.075‑0.1mm，所述聚苯乙烯层的厚度为0.03‑0.5mm，形成浮球颗粒的直径为0.135‑0.2mm，密度为1.03‑1.1g/cm3。该水泥浆体系密度和强度稳定，理论涉及和实际施工之间的随机误差小，降低了实际施工难度，提高工程质量的整体稳定性。
