Digital Ezperiment Steam and Incondensable Gas-assisted Gravity Push on Heavy Oil
Numerical simulation method is applied to study the procedure of Steam and incondensablegas-assisted gravity push(SAGP)on heavy oil,the parameters of the process.such as temperature andsaturation distribution．etc are obtained,the simulation results are analyzed and compared withsteam-assisted gravlty drainage(SAGD)on the same condition,some conclusions are drawn as follows：(1)during the upward spreading of steam chamber,the vertical expanding speed of SAGD is quickerthan SAGp,but its horizontal expanding speed is slower;(2)in this two technology,the cumulative oilof SAGP is slightly lower than that of SAGD,the final residual oil in the steam chamber of SAGD isless than SAGE but the cumulative oil-steam rate(OSR)of SAGP is larger than SAGD．namely,theeconomic effect of SAGP technology is better;(3)in the SAGP technology,when the proportion ofmcondensable gas is 20%,and other technology parameters are the same,the heat lost of SAGP is 79%of SAGD,OSR of SAGP is 0．03 higher than SAGD;(4)SAGP will be a more economical andprospected technology on heavy oil recovery．
