The Deliverability Evaluation of Abnormal High Pressure Gas Reservoir with Stress Sensitivity Model
Because the presence of stress sensitivity in abnormal high pressure gas reservoir will deteriorate the deliverability of gas well.the permeability stress sensitivity must be taken into account in the calculation of gas well deliverability.Herein the deliverability test data of a gas well is taken as an example, and its deliverability is calculated bythe adoption of pressure-squared, pseudo-pressure, and enhanced pseudo-pressure type equation, which take into consideration of stress sensitivity.It is shown from the results are that permeability stress sensitivity should be considered when constructing productivity equation, and the pressure-squared methods can be approximately applied to calculate deliverability.Based on the study of the effect of permeability stress sensitivity on gas well deliverability, it was found that the stronger the stress sensitivity is, the lower its deliverability declines.
