| Abstract: | Due to the low permeability and low pressure in heterogeneous heavy oil reservoir, the process string for the conventional steam stimulation is complex, and periodic oil-producing rate is low, gas-oil ratio and back water production rate is low and effective period is short . But using the nitrogen-assisted steam stimulation technology can simplify the process string, reduce the steam injection rate, improve the periodic oil production and back oil recovery rate. |

| Keywords: | low permeable heterogeneous reservoir nitrogen-assisted steam stimulation parameter optimization injection pattern field application |
