| Abstract: | Aimed at Gravity Override in a steam-injection processes,a well test analysis model of wedge-shaped compound reservoir is set up to simulate to slant steam front. 1'he mathematical mod-e1 considering heat loss is given and solved by Iaplace transfor-mation, then stehfest algorithm is used to obtain dismentionless wellbore pressure. The influence of the parameter on the dis-mentionless wellbore pressure is discussed, such as slant angle,heat loss, and mobility ratio. |
