Low temperature rapid hardening grouting material for offshore oil well and preparation method thereof
The invention relates to a low temperature rapid hardening grouting material for an offshore oil well. The low temperature rapid hardening grouting material for the offshore oil well comprises the following raw materials in parts by weight: 2,000 parts of gel materials, 950-965 parts of inorganic mineral active materials, 25-35 parts of retarders, 5-10 parts of anti-freezing ingredients, 3-5 parts of high efficiency slushing agents, and 0.1-0.3 part of defoaming agents, wherein the gel materials are quick-hardening sulphate aluminium cement and oil well cement; the mass ratio of the quick-hardening sulphate aluminium cement and oil well cement is 5:5-8:2. The invention also provides a preparation method thereof. The grouting material is suitable for construction under a well cementation low-temperature environment, slurry can maintain better mobility and is high in early strength, the slurry is full without shrinkage, the long-term strength is high, and the well cementation construction time and the underground grouting environment parameter requirement are effectively ensured.
