Abstract
The results of introduction in practice of the complex technology of well completion and well casing, developed in the Oktyabrsky branch of VNII GIS, aimed at quality casing in wells and increase of well service life, are evaluated. Briefly considered the stages of implementation of the technology in wells, presents materials of geophysical studies on basic and experimental wells, the results of technological efficiency of work. Conclusions are set out to assess the quality and technical and economic indicators of well cementing. When cementing casing strings, improvement of formation separation quality is observed. The probability of behind-the-casing flows decreases and the period of corrosion resistance of the casing increases. The necessity of further application of this technology as well as work on modernization of technical samples technology is noted.
