NEW MODEL FOR FRAC-PACKED WELL PRODUCTIVITY PREDICTION

    Graphical Abstract
    • Abstract
  • The productivity Prediction of the fracpacked well is the basis of frac-pack design.Stimulation effect caused by fracturing can be estimated by stimulation ratio.The effect of gravel-packing in screen-casing annular and perforations on the well productivity can be shown by gravel-pack productivity ratio,which can be calculated by the additional skin factor.The total productivity ratio of the frac-pack means the product of simulation ratio and gravel-pack productivity ratio.According to the IPR before the frac-pack job,which can be calculated by the testing data,the IPR curve of frac-packed well can be obtained,and the case study of Yan 6-8 well in Tuha oilfield proves the reliability of this new model.
