| Abstract: | chnical mechanism and laboratory core simulation experiment of in situ gas generating for enhanced oil recovery are introduced. Typical block is analyzed in detail. It is used in the field for 21 well-times. Average water injection pressure reduced 9. 5MPa, the average waterflood amount of single well increased 5321. 9m , the cumulative waterflood amount increased 111759m3, and cumulative incremental oil of oil wells is 15187. 49t. The field experiment shows that the application of this technology of in situ gas generating plays positive role in controlling water, stabilizing oil production and in controlling natural decline in partial block and well group, which is a new technology of EOR with application prospect. |
