摘要： The present invention relates to a liquid, self-breakable, temporary viscosifier agent (yield point enhancer) for oil based drilling muds, obtained by reacting one or more dicarboxylic fatty acids with a secondary dialkanolamine and thereafter with a tertiary tialkanolamine, and to oil based drilling muds containing it.
摘要翻译： 本发明涉及通过使一种或多种二羧酸脂肪酸与二次二链烷醇胺反应，然后与三级烷醇胺反应获得的油基钻井泥浆的液体，自破性临时增稠剂（屈服点增强剂）和油基 钻泥包含它。
