RESEARCH ON MUD RATIO OF DIRECTIONAL DRILLING IN ALKALINE WATER ENVIRONMENT BASED ON ORTHOGONAL EXPERIMENT
How to prepare a good mud to enable it to form a stable mud film in the pipeline to maintain the pipe wall stability is the focus of research in the industry.Taking the yellow river pipe crossing project as the background,using bentonite,carboxymethyl cellulose,sodium carbonate as other materials,we study the properties of mud under different ratios.The test results show that according to the background engineering of the project,bentonite∶cmc∶sodium carbonate∶water = 80∶4∶5∶900 is obtained by design orthogonal test.
