Enhanced well cementation cement slurry and application thereof
The invention relates to the technical field of preparation of cement paste in well drilling, and discloses enhanced well cementation cement paste and application thereof.The cement paste is prepared from, by weight, 100 parts of cement, 4-10 parts of filtrate reducer, 0.1-0.5 part of defoaming agent, 5-8 parts of nanometer filler, 1-5 parts of polyaniline/graphene intercalation compound, 35-110 parts of water and 0-30 parts of high-temperature stabilizer, 0-200 parts by weight of a density regulator, 0-2 parts by weight of a dispersant and 0-1.5 parts by weight of a retarder. According to the enhanced well cementation cement slurry provided by the invention, the polyaniline/graphene intercalation compound is added, so that the overall mechanical strength of well cementation cement can be effectively improved, and the enhanced well cementation cement slurry can be suitable for API (American Petroleum Institute) all-level oil well cement.
本发明涉及钻井中水泥浆制备技术领域，公开了一种增强型固井水泥浆及其应用，所述水泥浆包括：100重量份水泥，4‑10重量份降滤失剂，0.1‑0.5重量份消泡剂，5‑8重量份纳米填充剂，1‑5重量份聚苯胺/石墨烯插层复合物，35‑110重量份水，0‑30重量份高温稳定剂，0‑200重量份密度调节剂，0‑2重量份分散剂，0‑1.5重量份缓凝剂。本发明提供的增强型固井水泥浆，通过添加聚苯胺/石墨烯插层复合物，可有效提高固井水泥的整体力学强度，能适用于API各级油井水泥。
