摘要
以工业玉米淀粉为原料,在氢氧化钠存在下,以氯代磷酸酯为醚化剂,合成了3—磷酸酯基—2—羟基丙基淀粉醚。经室内钻井液性能评价,认为该产品具有良好的抗盐抗钙降滤失能力,适用于淡水、盐水和饱和盐水钻井液。
This paper presents synthesis of starch derivate PHPS. In indoor performance evaluation,it's shown that it has good salt-resisting,anti-calcium and fluid loss property.It is suitable for fresh water,brine and saturated salt water drilling fluid.
