摘要：
An oil well cement slurry high-temperature suspension stabilizer prepared from oil-based shale drilling cuttings is provided. The high-temperature suspension stabilizer is reasonable in principle, inexpensive and easily available in raw materials, high in product uniformity and good in chemical stability. Meanwhile, waste is changed into wealth. Therefore, the high-temperature suspension stabilizer is environment-friendly and has a broad industrial application prospect.
