Temperature-resistant composite lightweight material low-density well cementation cement
The invention discloses temperature-resistant composite lightweight material low-density well cementation cement. The temperature-resistant composite lightweight material low-density well cementation cement comprises the following components in parts by mass: 100 parts of oil well cement; 20-30 parts of a reinforcing material; 10-20 parts of a composite lightweight material; 0.5 to 1.0 part of a suspension stabilizer; 0.5 to 1.5 parts of an early strength agent; 0.3 to 0.5 part of a dispersant; 1.0 to 2.5 parts of a fluid loss agent; 0.5 to 1.5 parts of a retarder; the composite lightening material adopts a composite material containing expanded perlite micro powder, so that on the premise of controlling the cost and reducing the density of the cement paste, the rheological property and the stability of the paste can be ensured, and the mechanical property of set cement can be improved.
本发明公开了一种耐温复合减轻材料低密度固井水泥,按质量份数计包括以下组分:油井水泥100份;增强材料20‑30份;复合减轻材料10‑20份;悬浮稳定剂0.5‑1.0份;早强剂0.5‑1.5份;分散剂0.3‑0.5份;降失水剂1.0‑2.5份;缓凝剂0.5‑1.5份;消泡剂0.2份,其中,复合减轻材料采用包括膨胀珍珠岩微粉在内的复合材料,在控制成本和降低水泥浆密度的前提条件下,既可保证浆体的流变性能和稳定性,又可改善水泥石的力学性能。
