Low-density cement paste and preparation method thereof
The invention relates to low-density cement paste which comprises the following components in parts by weight: 100 parts of cement; 15 to 20 parts of micro silicon; 23 to 27 parts of microbeads; 2-4 parts of a suspending agent; 4-7 parts of a fluid loss agent; 2 to 3 parts of a retarder; 2-3 parts of a drag reducer; 0.1 to 0.2 part of a defoaming agent; and 80 to 85 parts of water. The cement paste has the advantages that the cement paste is fast in cement feeding, good in rheological property, good in stability at high temperature, excellent in water loss and fast in compressive strength development, and the cement paste is high in well cementation quality and high in operation efficiency.
本发明涉及一种低密度水泥浆，包括以下重量份数的组分：水泥，100份；微硅，15~20份；微珠，23~27份；悬浮剂，2~4份；降失水剂，4~7份；缓凝剂，2~3份；减阻剂，2~3份；消泡剂，0.1~0.2份；水，80～85份。本发明的优点是，该水泥浆下灰快、流变性佳、高温下稳定性好、失水优、抗压强度发展快，用该水泥浆固井质量高，作业效率高。
