High-temperature-resistant cement for well cementation of deep and ultra-deep wells
The invention relates to the technical field of well cementation materials for oil and gas wells, in particular to high-temperature-resistant cement for well cementation of deep and ultra-deep wells, which comprises the following components in parts by weight: 40-50 parts of oil well cement, 10-20 parts of quartz powder, 30-45 parts of lattice distortion induction material and 0.3-1 part of steric hindrance material. According to the invention, the problems of strength decline and permeability increase of the existing cement system are solved, and the strength stability of set cement in an ultrahigh-temperature stratum environment is improved.
本发明涉及油气井固井材料技术领域，具体涉及一种深地超深井固井用耐高温水泥，所述水泥包括按重量份计的以下组分：40‑50份油井水泥、10‑20份石英粉、30‑45份晶格畸变诱导材料、0.3‑1份空间位阻材料。本发明解决目前水泥体系存在的强度衰退、渗透率增加的问题，提高了水泥石在超高温地层环境中的强度稳定性。
