Application of Hole Jet Scale Removal Technology in De-su Oil Pipeline
Due to the decline of oilfield production,De-su oil pipeline adopts water-bearing oil transmission.In order to reduce the operating pressure of Su-1-lian sewage station,the operation mode of high temperature and low transportation volume is adopted,resulting in serious pipe scaling and reduction of the effective diameter of the pipeline,which seriously affects the safe and stable operation of the pipeline.The hole jet scaling technology was used to successfully realize the pigging and ball passing of the whole line of the De-Su oil pipeline,which effectively removed the fouling in the pipeline and reduced the external transmission pressure of De-su.The cleaning process has the advantages of safety,speed and no environmental pollution,which is of great significance to the operation and management of oil pipelines in Hailar Oilfield.
