Introduction: Buriedgeothermaloilpipelinesplayavitalroleinthetransportationofcrudeoilfromextractionsitestorefineriesorstoragefacilities.However,thesolidificationofcrudeoilwithinpipelinescancauseseveraloperationalissues,suchasflowrestrictions,increasedpressure,andpotentialpipedamage.Therefore,itisessentialtoanalyzethefactorsthataffectthesolidificationtimeinordertooptimizepipelinedesignandoperation. 1.GeologicalConditions: Thegeologicalconditionsofthepipelinelocationcansignificantlyimpactthesolidificationtime.Factorssuchasthedepthandcompositionofthesoilsurroundingthepipeline,aswellasthepresenceofgroundwater,caninfluencetherateofheattransfer.Soilwithhighthermalconductivityandlowmoisturecontentpromotesfasterheatdissipation,whichmayleadtoquickersolidification.Conversely,soilwithlowthermalconductivityandhighmoisturecontentmayimpedeheatdissipation,resultinginlongersolidificationtimes. 2.PipeDesign: Thedesignofthepipelineitselfalsoaffectsthesolidificationtime.Thethicknessandmaterialofthepipelineinfluencetherateofheattransfer.Thickerpipestendtoretainmoreheatandslowdownthesolidificationprocess.Additionally,thethermalconductivityofthepipelinematerialandthepresenceofinsulationlayerscanimpactheatdissipation.Properinsulationmaterialsandtechniques,suchaspolyurethanefoamormineralwool,canminimizeheatloss,therebyreducingsolidificationtime. 3.InsulationMethods: Thechoiceofinsulationmethodiscrucialformaintainingtheheatwithinthepipeline.Externalinsulationmethods,suchaswrappingthepipelinewithinsu
