合成了一种无毒、具有强抑制性兼一定降滤失、降摩阻功能的新型多元醇类处理剂PE-Ⅰ,并在新疆红山嘴、石西地区进行了4口井的现场试验。结果表明,PE-Ⅰ的使用,有利于钻井液体系组成的简化,有利于钻井液性能的改善和调节,有利于钻井施工。
A new kind of polyalcohol treatment agent PE-Ⅰ which is non-toxic, has strong inhibition and also has some functions of filtration loss and friction reduction has been synthesized, and four wells were tested in Hongshanzui and Shixi areas of Xinjiang . The results show that the use of PE-Ⅰ is conducive to the simplification of drilling fluid system composition, which is good for the improvement and adjustment of drilling fluid properties, which is good for drilling construction.
