“泥浆”被人们誉为钻井的血液。但如何做到合理使用，发挥泥浆应有的护孔作用，这个问题过去在四一六队一直没有解决。去年，队院共同配合，在上级党委与省地质局的正确领导下，以“鞍钢宪法”为指针，以路线斗争为纲，经过近半年的反复试验（共试验37次），试制成功了一种粘土粉。通过现场使用证明：它具有提高泥浆质量，减少孔内事故，提高钻进效率，减轻笨重体力劳动等优点，现将制造情况介绍如下，供其他单位参考。 “Slurry” is hailed as the blood of drilling. However, how to achieve reasonable use and play the role of mud protection holes should not be solved in the past in the 416th team. Last year, the team collaborated with each other and under the correct leadership of the higher Party Committee and the Provincial Bureau of Geology, taking the “Anshan Iron and Steel Constitution” as a guideline, taking the line struggle as the guideline, and after nearly half a year of repeated trials (a total of 37 trials), the trial was successful. Clay powder. Proved by on-site use: It has the advantages of improving mud quality, reducing hole accidents, improving drilling efficiency, and reducing bulky physical labor. Now the manufacturing situation is introduced as follows for reference by other organizations.
