NEW AND REASONABLE TUBING CENTRALIZER ARRANGEMENT METHOD OF POLYMER FLOODING ARTIFICIAL LIFTING WELL

Centralization for tubing is one of the important methods to prevent eccentrical rub. According to the mechanism research of tubing bending by the when the tubing burdens axial pressure and lifting viscous liquids, the paper builds the experienced formula to calculate the normal force by the axial force and viscous liquids lifting, and then recommend the reasonable tubing centralizer arrangement method based on the tubing bending analysis. This method has developed the software to design the centralizer arrangement for polymer flooding artificial lifting well.
