| During the recovery of light oil, paraffin precipitation is a very important factor affecting the normal production of oil wells. The mechanism of paraffin precipitation in oil wells, pour point reducing and paraffin control are studied in the paper with the high pour point oil in Liaohe Oilfield as the research subject. A new paraffin control cold transportation agent is developed and its performance is evaluated in the lab and the technology for adding the agent is studied. The test results indicate that the paraffin control cold transportation agent is effective in paraffin control, which can reduce the freezing point of the crude oil significantly and meet the requirements of cold transportation. Field tests are also conducted with obvious results obtained with the hot washing cycle prolonged greatly and the fluid rate and electric current being stable during the tests. |
