The article provides brief information about the designs of drainage wellhead structures used in modern reclamation practice; experimental design of a new wellhead structure of the type EDW is presented; the cost per unit of a wellhead structure device for various diameters and types was calculated under comparable conditions. Based on the data obtained, a feasibility study was conducted on the structure of wellhead structures of various types and diameters; justified the use of wellhead construction type EDW.
