This paper focuses on the wellbore instability problems in the process of drilling and developes a drilling fluid system suitable for this block, to improve the drilling speed, reduce the downhole complex accidents. The shale clay composition, the microstructure and the hydration performance of the collapse-prone section in Myanmar block D are analyzed. In view of the existing problems of the early used drilling fluid, the appropriate impermeable and anti-collapse drilling fluid formulation is optimized. The laboratory experiment and evaluation results show that the impermeable and anti-collapse prevention drilling fluids have a strong ability to resist pollution, a good temperature resistance, good clay shale inhibition ability and block ability. In the process of the field application in 4 wells, the drilling fluid shows a good effect on the wellbore stability and can effectively solve the problems of the borehole collapse and the hole enlargement, significantly reduce the downhole complex accidents., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=6vELipUAHQhjuQOO+c7tgQ==, pdfFileSize=1022052, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
