天然材料改性钻井液处理剂研究与应用

摘要

The study and application of water soluble natural material modified drilling fluid additives are introduced. The titled additives can be used as mud filtration reducer, thinner and collapse inhibitor. In addition, these additives have high-temperature stability and can restrain shale from hydrating expansion.%介绍了水溶性天然材料改性钻井液处理剂的研究与应用情况。水溶性天然材料改性产品在钻井液中可起到降滤失、降粘、高温稳定、抑制页岩水化膨胀和防塌等作用。
