Method for exploiting crude oil in gas-containing heavy oil reservoir through underground electric heating

The invention provides a method for extracting crude oil through underground electric heating of a gas-containing heavy oil reservoir, which comprises the following steps of: (1) carrying out CO2 energy storage volume fracturing operation on a horizontal well in the gas-containing heavy oil reservoir, so that a hydraulic fracturing fracture network is uniformly developed on a horizontal section; (2) a thermosensitive proppant is laid in the horizontal section fracturing crack, and a heat transfer network is formed; (3) a heating cable is put down into the horizontal section shaft, and the horizontal section oil layer is electrically heated to reach the preset shaft temperature; (4) opening the well for recovery and controlling the daily fluid production within a preset range; (5) when the daily oil production is smaller than a preset value, injecting a viscosity reducer, gas and a foam promoting system into the bottom of the well and soaking the well; (6) opening the well for recovery and controlling the dail
