无固相冲洗液是六十年代发展起来的一种钻探冲洗液.山于它具有提高钻速、降低磨阻、减少运输量等优点,因而受到人们的重视.近年来,无固相冲洗液的品种不断增加,应用范围进一步扩大.但是,目前的无固相冲洗液,如聚丙烯酰胺清水溶液、生物聚合物溶液、羟乙基纤维素溶液等,由于成本高、用量大、失水性能差而限制 Solid-free rinse liquid developed in the 1960s is a kind of drilling rinse solution, which has attracted people’s attention due to its advantages such as increasing drilling speed, reducing grinding resistance and reducing the volume of transportation. In recent years, Of the growing variety of applications to further expand.However, the current non-solid rinse, such as polyacrylamide solution, biological polymer solution, hydroxyethyl cellulose solution, due to high cost, large amount of water loss performance Poor and limited
