Leaking stoppage cement paste and application thereof
The invention relates to the technical field of well cementation, and discloses leaking stoppage cement paste which comprises the following components in parts by weight: 100 parts of cement, 10-35 parts of a temperature-sensitive expansion material, 4-10 parts of a filtrate reducer, 5-8 parts of a nano filler, 0.1-0.5 part of a defoaming agent, 0-30 parts of a high-temperature stabilizer and 0-200 parts of a density regulator, 0-2 parts by weight of a dispersant, 0-1.5 parts by weight of a retarder, and 35-110 parts by weight of water. The plugging cement slurry provided by the invention has the advantages of good compatibility among the components, stable slurry property, effective plugging of 4mm cracks, bearing capacity greater than 10MPa, high leakage plugging capacity, improvement of the bearing capacity of malignant leakage stratums, and good application and popularization values.
本发明涉及固井技术领域，公开了一种堵漏水泥浆，所述水泥浆包括：100重量份的水泥，10‑35重量份的温敏型膨胀材料，4‑10重量份的降滤失剂，5‑8重量份的纳米填充剂，0.1‑0.5重量份的消泡剂，0‑30重量份的高温稳定剂，0‑200重量份的密度调节剂，0‑2重量份的分散剂，0‑1.5重量份的缓凝剂，35‑110重量份的水。本发明提供的堵漏水泥浆，各组分之间的相容性好，浆液性质稳定，能有效封堵4mm裂缝，承压能力大于10MPa，表现出了较强漏失封堵能力，能够提高恶性漏失地层的承压能力，具有较好的应用和推广价值。
