用不同的季胺盐表面活性剂与钠土反应，制备适合于JHB合成基液的有机土，评价合成基钻井液热滚80℃、12h前后的性能。优选出具有增粘、降失水、钻井液性能稳定的1231有机土。其制备条件：1231活性剂与钠土质量之比为1：1；活化温度是50～70℃；活化时间为24一36h。
Different quaternary ammonium salt surfactants were reacted with sodium hydroxide to prepare organic soil suitable for JHB synthetic base fluid, and the performance of synthetic drilling fluid hot rolling was evaluated before and after 80 ℃ and 12h. 1231 organic soil with thickening, loss of water loss and stable drilling fluid performance is preferred. The preparation conditions: 1231 active agent and sodium mass ratio of 1: 1; activation temperature is 50 ~ 70 ℃; activation time is 24 to 36h.
