Zusammenfassung:	The process of fixation of wells in fluid layers comprises lowering a drive pipe to the well, with pumping in grouting mortar to the annular space of the well. With the first section of the drive pipe one closes the interval of the fluid layers, withpressing the corrosion-resistant grouting mortar to the interval of bedding of the fluid layers; at the mouth one forms excess pressure and keeps it in the annular space of the well during the process of washing and curing. At that, as corrosion-resistant grouting mortar one uses the slag-sand grouting cement with addition of grouting Portland cement, plasticizer, saturated solution of sodium chloride and foam suppressor.
