摘要: 对于油基钻井液而言润湿反转剂是一种重要的处理剂。在此优选出了一种新型的阳离子表面活性剂XNWET作为油基钻井液的润湿反转剂;它具有来源广、价格低、亲油性强的特点。陈化前后对比实验表明,在220 ℃高温下,XNWET 仍能与亲水性固体有很好的吸咐性能,其最优加量为1. 2 g/ 100 g 重晶石。

关键词: 润湿反转剂, 油基钻井液, 亲油性, 亲水性, 高温

Abstract:

Wettability reversal agent is an important additive for oil ase drilling fluid. In this paper , a new cationic surfactant(XNWET) has been used as the wettability reversal agent in oilbase drilling fluid , which has widely source , lower price andstrong lipophilic capability. The contrasting experiments before
or after heat rolling have shown that XNWET still has good adsorption with hydrophilic solid at 220 ℃. The best dose of the gent is 1. 2 g/ (100g) barite.

Key words: wettability reversal agent, oil base drilling fluid, oil wettabillity, water wettability, high temperature
