摘要：
Considering the stress sensitivity effect and thermal effect of the wellbore, the governing equation for bottom-hole pressure in tight gas reservoirs is proposed in this paper. Defining a gas pseudo-pressure term, the equation is linearized and then solved with the semi-analytical method. The normal pressure and derivative result is analyzed on a log-log plot, and further the influence of thermal effect on pressure and derivative is discussed. Validation with field test data is carried out and results show that the fluidic-thermal coupling well-test model fits well with in-situ data and is applicable for tight gas reservoirs.
