Abstract:

Forecasting the deliverability of horizontal well accurately plays an important part in economical and effective exploitation of oil and gas field. When we use horizontal well to exploit oil and gas field, the flow processing includes reservoir flow and wellbore flow. Taking both non-uniform damage around wellbore and pressure drop along the wellbore into account, we establish a semi-analytic model to estimate the deliverability of horizontal gas well. Then use this new model to calculate the production of a horizontal gas well, compare with the production under uniform damage, and respectively analyze the effect of pressure drop along the wellbore under different permeability and non-uniform damage around wellbore on well deliverability. This new model can provide theoretical basis for the deliverability analysis for horizontal gas well and multilateral gas well.
