Studies On Heavy Oil Characteristic And Dehydration Means Of Block JangQiao

Block JangQiao is a new block of Heavy oil and lies outlying areas of the Ninth Factory,itis exploit experiment step now. disposing Heavy oil encountered more difficult than the generalon the recovery and transport of crude oil,because Heavy oil is a complex mixture ofhydrocarbons,it comprise more asphaltine and colloid,characterized by high density,highviscosity,poor mobility,mobile feature far from Newton law,making it difficult to normalrecovery and transport,in order to recovery this Block more effectively and economically,thispaper start from indoor experiments, researched systematacially Physical properties andRheologic properties and dehydration technology of Block QiangQiao Heavy oil, consisting ofseveral parts as follows: Analyzed density,pour point,freezing point,initial boiling point,wax content ,asphaltine,colloid,sulfur content and other physical chemical properties of Heavy oil,andresearched formulate method of Heavy oil and effect factors;researched systematacially theeffects of heating temperature,shear rate,water content ratio and demulsifier on the Heavy oilviscosity;in order to give the best dehydration means,had two stages thermo-chemicaldehydration experiment and electrical dehydration experiment,discussed the effects of heatingtemperature,dewatering time,emulsifier,the field intensity and the pole on the Heavy oildehydration.Through the above research,understood the Change law of Heavy oil Physicalproperties,recognized the Rheologic propertes of Heavy oil evolution and researcheddehydration technology of Block JiangQiao,given theoretical basis on estimating of crude oiland recognizing of underground percolation principle,established Heavy oil recoveryprogrammes and transport programmes,and given the best dehydration method.it is greatsignificant for recoverying effectively and lowing operational costs of ground.
