Deliverability Prediction of Gas Condensate Wells Based on Statistics

Abstract

The deliverability of gas condensate well can be calculated by using the modified deliverability equation of dry gas well and the pseudopressure deliverability equation. The modified deliverability equation of dry gas well, without considering the effect of condensate accumulation on the gas flow, results in a relatively large error; the practical application of the pseudopressure deliverability equation is not widespread because of the complex in calculating process of the pseudopressure function. The gas relative permeability and pressure is correlated based on the statistics of gas condensate wells, and an accurate and convenient deliverability equation of gas condensate well is derived. The results of case studies verify that the deliverability equation of gas condensate wells proposed is more appropriate to predict the production of the gas condensate wells.
