The invention provides an intelligent separate production process pipe column and a control method, the intelligent separate production process pipe column comprises a computer and a ground controller, and further comprises an oil pipe arranged in a shaft, a plurality of groups of sealing and distributing devices are mounted in series between short sections of the oil pipe, each group of sealing and distributing device comprises a cable passing packer and an intelligent separate production bottom-hole regulator which are arranged up and down, and a screwed plug is mounted at the bottommost end of the oil pipe; and the intelligent separate mining bottom-hole regulator is connected to the ground controller through a cable. The intelligent separate production bottom-hole regulator can realize real-time monitoring of layered pressure, flow, moisture content and temperature, and also can realize layer selection production and fine bottom-hole regulator under the condition of immobile string, thereby achieving the
