A linkage control method for oilfield water source wells and water supply and injection stations

The invention discloses a linkage control method for water source wells and a water supply and injection station of an oil field. The method comprises the following steps that 1, the first water source well is started to supply water to a water storage tank; 2, the second water source well is additionally arranged to supply water to the water storage tank; and 3, the liquid level change of the water storage tank is monitored in real time to increase or decrease water supply of the water source wells. According to the linkage control method, air in a pipe is discharged in advance through an emptying electromagnetic valve on an emptying pipe, and the problem that the back pressure of well mouths of the water source wells is large, and the starting current is too large when an electric submersible pump is started, so that the electric submersible pump cannot be started is solved; the electric submersible pump is controlled through a frequency converter, and thus electricity and energy aresaved; an inclined connecting water pipe and a check valve are matched to accumulate water flow, the air in the pipe is squeezed out, and the pressure in the pipe is reduced; and a three-phase electric parameter acquisition module is used for detecting the fault of the electric submersible pump, a plurality of water source well control units work cooperatively in a linkage mode according to the water level in the water storage tank, and thus the efficiency is high.
