Low-thixotropy, low-density and high-strength cement paste
The invention discloses low-thixotropy, low-density and high-strength cement paste, and belongs to the technical field of oil-gas well cementation cementing materials. The cement paste system is prepared from the following raw materials by weight: 40-60% of oil well cement, 15-20% of sulphoaluminate cement, 30-40% of floating beads, 3-9% of additive and 0.02-0.04 % of grinding aid. The low-thixotropy, low-density and high-strength cement paste system has the characteristics of low density, high strength, good rheological property and stability, high temperature resistance, corrosion resistance, durability and the like.
本发明公开了一种低触变性低密度高强度水泥浆，属于油气井固井胶凝材料技术领域。所述水泥浆体系按重量百分比计包括以下原材料：油井水泥40～60％，硫铝酸盐水泥15～20％，漂珠30～40％，外加剂3～9％，助磨剂0.02～0.04％。本发明的低触变性低密度高强度水泥浆体系，具有密度低、强度高，流变性及稳定性好，耐高温、耐腐蚀及耐久性等特性。
