Abstract

For the paraffin deposition in the well bore equipped with sucker-rod pump, this paper, based on the mathematical model for transient temperature prediction in the wellbore equipped with sucker-rod pump, makes the prediction results of the temperature distribution in the wellbore with different yield of 10-18 wells in D1 area. It is found that the change of wellhead temperature is affected by some factors such as oil production, tubing size, thermal conductivity, surface roughness and flowing production time. Therefore, we get the paraffin deposition law in the well bore equipped with sucker-rod pump.
