Fracturing flow-back gas production integrated pipe column

The utility model discloses a fracturing flow-back gas production integrated pipe column which comprises a casing pipe and an oil pipe, the casing pipe is sleeved on the outer side of the oil pipe, anannular space is formed between the oil pipe and the inner wall of the casing pipe, a pressurizing pipe is arranged on one side of the oil pipe, the top end of the pressurizing pipe is communicated with an air pump, and the bottom end of the pressurizing pipe is communicated with a first valve body. And the first valve body is fixedly connected with the outer wall of the oil pipe. Through the arrangement of the sleeve and the oil pipe, gas collection can be completed through an annular space formed by the sleeve and the oil pipe, accumulated liquid and gas can be actively discharged through the oil pipe, nitrogen is pumped into the oil pipe through the pressurizing pipe and the air pump in the later stage of oil and gas exploitation, the air pressure in the oil pipe can be effectively improved, and the production
