[0014] Refer to Figure 1-Figure 4 , A low-permeability horizontal well production and injection process string, including tubing string, pump, bridge packer A, bridge packer B, inner pipe, bridge diverter valve, dispenser. The pump 1, the bridge packer A3, the bridge diverter valve 6, the bridge packer B7 and the dispenser 8 are installed and connected to the oil pipe 4 in sequence. The inner pipe 5 is installed in the oil pipe 4, the middle part is connected with the bridge diverter valve 6, and the two ends are connected with the bridge packer A3 and the bridge packer B7.
[0015] The pump 1 is located in the vertical well section inside the casing 2. The bridge packer A3 is located before the mining layer, and the bridge packer B7 is located between the production zone and the injection zone in the mining zone. The bridge-type diverter valve 6 is located in the mining layer in the mining layer, and is provided with a diverter conversion mechanism. The shunt switching mechanism ...
