The simulations of the bullheading parameters show that, the kill time decreases and the bottom pressure and the casing pressure increase with the increase of the pump displacement; both the formation permeability and the permeable formation height have a little influence on the pressure in the first stage, but when the high permeable formation or the high height formation enters into the second and third stages, both the bottom pressure and the casing pressure decrease with the increase of the formation permeability or the formation height, and the change range becomes small. In addition, typical bullheading curves are obtained by analyzing the characteristics of the bottom pressure and the casing. The predicted model had a good agreement with the field test. This can provide a theoretical basis and guidance for the selection of killing methods and the design of bullheading., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=9H+8fgDTm5Uh1btesMfrLw==, pdfFileSize=2214034, 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.
