Construction method of inflow distribution well

The invention relates to a construction method of an inflow distribution well. The construction method of an inflow distribution well comprises the steps that a surrounding structure is constructed onthe periphery of the area of the inflow distribution well to be constructed; a well body of the inflow distribution well is formed at the position of the inflow distribution well to be constructed, and a communication hole is formed in the side of a well bore; earth mass is excavated downwards in the well bore, so that the well bore sinks down until the bottom of the well bore reaches the set elevation; a bottom plate is constructed at the bottom of the well bore to block the bottom of the well bore, a water pipe is arranged to enable the water pipe to be connected with the communication hole; and a top plate for sealing the well bore is constructed at the top of the well bore to form the inflow distribution well. The problem of low construction efficiency of the inflow distribution wellis effectively solved, and
