国家地质总局泥浆经验交流会于三月二十六日—四月二日在安徽淮北市召开，出席代表一百八十二人。会议重点交流了安徽三二五地质队、上海地质处等九单位关于聚丙烯酰胺低固相泥浆和超早强水泥的使用经验，参观了三二五队钻探现场和泥浆试验室，听取了天津大学、山东大学有关学术报告。十个省的使用经验表明，聚丙烯酰胺低固相泥浆在钻进复杂岩层方面显示了很大优越性，它有六大优点：固相含量低，比重轻；护壁防塌性能好；泥浆净化好，含砂量低；润滑性好，有利于开高转速；流变性好，粘度随流速 The SEPA Mud Experience Exchange Meeting was held in Huaibei City, Anhui Province from March 26 to April 2, with a total of 182 representatives. The meeting focused on the exchange of Anhui 25th geological team, the Shanghai Geological Department and other nine units on polyacrylamide low solid mud and ultra-early strength cement experience, visited the March 25th drilling site and mud laboratory, listening to Tianjin University, Shandong University for Academic Report. The experience of ten provinces shows that polyacrylamide low-solid mud shows great superiority in drilling complex rock formations. It has six advantages: low solid content, light weight, good anti-collapse performance of mud wall, Good, low sand content; good lubricity, open high speed; good rheology, viscosity with the flow rate
