摘要

摘要: 膨润土的质量好坏不但影响所配钻井液性能，而且关系到所配钻井液接受化学处理剂的能力，使用不合格的膨润土，不但用量大，而且需要用更多的药剂进行处理，极不经济，以市场上使用的不同厂家的钻井级膨润土和OCMA膨润土为研究目标，分别考察了在室温、高温（120℃、150℃和180℃）养护条件下不同厂家钻井级膨润土、OCMA膨润土与天然钠膨润土粉、钠化钙膨润土粉的性能差异，并对钻井级膨润土与OCMA级膨润土在现场使用过程中可能存在的问题进行了探讨。结果表明：采用现有标准技术指标来判定膨润土的质量已不适应膨润土质量的现状，进一步提出通过增加悬浮液高温养护后的表观黏度指标，来控制钻井液用膨润土质量。

Abstract: The quality of bentonite not only affects the performance of the drilling fluids made; it also affects the compatibility of the bentonite slurry with other mud chemicals. It is economically unreasonably to formulate drilling fluids with bentonite of poor quality because too much bentonite and chemicals will be consumed to formulate a drilling fluid of the same properties. Property differences between several drilling grade bentonites, OCMA clays and naturally obtained sodium bentonite, artificial sodium bentonite have been studied in laboratory under room temperature and high temperatures (120, 150and 180℃). Problems that may arise in field use of drilling grade bentonite and OCMA clay were investigated. It has been shown that the technical indices in bentonite evaluating standards currently in use are not able to meet the requirements of evaluating the bentonites in use presently. The paper further suggests that apparent viscosity of bentonite suspension being aged at elevated temperatures should be used as a criterion to control the quality of drilling bentonite.
