聚合醇钻井液高温稳定性的研究

The Study of High-temperature Stability of the Polyol

研究了在钻井液淡水体系和盐水体系中加入聚合醇对降滤失剂滤失量的影响。结果表明 ,钻井液体系中加入聚合醇能有效提高降滤失剂的耐温性 ,盐水钻井液比淡水钻井液体系提高降滤失剂高温稳定性的效果更加明显。

The influence of polyol on water loss of the fluid loss agent was researched in the fresh water drilling fluid system and the salt water drilling fluid system. The results showed that the ployol in the drilling fluid system can enhance the high temperature stability of the fluid loss agent effectively. The polyol in the salt water drilling fluid system enhances the high temperature stability more effectively than that in the fresh water drilling fluid system.
