Abstract

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
