Title: Analysis and improvement of natural gas huff and puff pilot for extra deep heavy oil reservoir
Abstract: Compared with CO2 huff and puff for producing heavy oil at abroad,the pilot test of natural gas huff and puff for deep heavy oil in the Yuxi block of the Tuha oilfield has seen high natural gas utilization rate and remarkable oil increment.Through literature investigation and numerical simulation,three methods are proposed to further improve the development effect of natural gas huff and puff,i.e.to improve gas injection rate and fracturing radius,to test for hybrid gas huff and puff at different gas proportions,and to maintain reservoir pressure by injecting water.
