Abstract

Abstract: Due to the problem of sustained casing pressure in the trapped annulus of gas reservoir injection-production wells, we develop a calculation model for sustained casing pressure under changing temperature and pressure of the production tubular column. An analysis model is first established for the trapped annulus according to a site-specific simplified structure of the actual gas reservoir. Next, based on the plane strain theory of elasticity, the thermal expansion and contraction properties of the material and the PVT equation of state for fluids, a mathematical analysis model is constructed. Finally, when the raw well data is considered, it is clear that the temperature change in the gas reservoir injection-production well is the main factor affecting the formation of the annular pressure. When only the effects of temperature and pressure on the protecting fluid are considered, this protocol meets the engineering requirements on site, with an error less than 5% and calculated results in good agreement with field data. This method facilitates the rapid prediction of annulus pressure in the field.

Key words: gas reservoir, injection-production wells, trapped annulus, annular pressure, sustained casing pressure
