摘要

摘要: 针对普通加砂水泥石经受高温后抗压强度衰退的问题，研发出一种油井水泥石高温稳定剂，该稳定剂对水泥浆的稠化时间、水泥石常温强度发育、流变性无副作用，与油井水泥外加剂配伍性良好，形成的水泥石高温下（320℃、450℃）抗压强度不衰退，优于加砂水泥石及超细二氧化硅水泥石。同时加入高温稳定剂的水泥浆还具有很好的胶结强度，约是加砂水泥石环的4倍，超细二氧化硅水泥石环的3.5倍。该高温稳定剂在蒙古林油田现场应用2口井，整个施工过程顺利，固井质量较好，一二界面胶结质量良好，具有良好的应用前景。

Abstract: A high temperature stabilizer has been developed for use in cement slurries to deal with decline of compressive strength of common set cement with sand at elevated temperatures. This stabilizer is well compatible with other additives in cement slurries and has no side effects on the thickening time and the development of the strength of the set cement at room temperatures. A set cement treated with this stabilizer had compressive strength that did not decline at elevated temperatures (320℃ and 450℃, respectively), showing better properties than set cement with sand and ultra-fine silica set cement. Cement slurries treated with this high temperature stabilizer had good cementation strength, which is 4 times of the cementation strength of cement sheath formed by cement slurries with sand, and 3.5 times of the cementation strength of the ultra-fine silica cement sheath. Operation of two wells with this high temperature stabilizer in Block Menggulin was successful and good well cementing job was performed, the cementation between the casing string and cement sheath as wells as the cementation between the cement sheath and the borehole wall were satisfactory, indicating that the high temperature stabilizer has good application prospect.
