Study on stress sensitivity effect on flow dynamic features of gas wells
Online published: 2010-12-15
The rock stress sensitivity will apparently affect the development performance in the process of reservoirs developing, especially in the development of low permeability reservoirs and volcanic reservoirs. The mathematical model is established by using the transient flow theory under the consideration of stress sensitivity and the skin
coefficient, and the solution of the real space is obtained by means of the Stehfest numerical inversion. On the basis of the varying relation between the dimensionless rate and dimensionless time, the influences of skin coefficient, dimensionless stress sensitivity, closed boundary and constant pressure boundary on the dynamic features of gas wells are analyzed. The research result shows that to reasonably develop gas reservoirs with stress sensitivity can make sure of the gas wells and reservoirs producing normally.
