Well cementation cement for coal rock gas well
The invention relates to the technical field of oil and gas well cementing materials, in particular to coal rock gas well cementing cement, which is prepared from the following components in parts by weight: 50 to 65 parts of high-magnesium Portland cement, 20 to 35 parts of high-aluminum active mineral admixture, 10 to 20 parts of gypsum, 2 to 5 parts of waterborne polyurethane and 0.2 to 0.5 part of multilayer sulfonated graphene. The invention mainly solves the problem of poor well cementation quality caused by poor cementation quality of the second interface of the well cementation cement stone of the coal-rock gas well, effectively improves the sealing property of the cement sheath and the stratum, and improves the well cementation quality of the coal-rock gas well.
本发明涉及油气井固井材料技术领域，具体涉及一种煤岩气井固井水泥，所述固井水泥包括按重量份计的以下组分：50‑65份高镁硅酸盐水泥、20‑35份高铝质活性矿物外掺料、10‑20份石膏、2‑5份水性聚氨酯、0.2‑0.5份多层磺化石墨烯。本发明主要解决煤岩气井固井水泥石第二界面胶结质量差导致的固井质量差的问题，有效提高水泥环与地层的密封性，提高煤岩气井固井质量。
