Key words: low-waste water shut of technologies, killing of a well, residual resistance factor, rain-technology, temporary plugging productive formation, mutual neutralization.

The article presents ways to improve water inflow control technologies in production wells and the repair and insulation works in injectors. Perfecting these technologies lies in their cost reduction by eliminating the pre-lifting pump from the well. Such work on water shut off in producing wells is recommended to be carried out simultaneously with their preparation for the current repair. The complex technology for such work, including water shut off works, killing and the acid stimulation wells was offer. It proposed to use in the composition of the «IMR» as plugging composition. The expediency of insulation works in injection wells to eliminate casing flow sediment using the compositions was shown. It is recommended to temporarily isolate the productive layer of mudding by such compositions. The technology of temporary producing formation isolation with a guar gel and other reagents was offer.
