FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises forcing working fluid via short pipe of string to top seam and working fluid via long pipe tubing equipped packer to bottom seam. Going-in of downhole instruments or inserted pipe via control head and long pipe string. Well is analysed by downhole surveying instruments. Technological jobs are performed with the help of inserted pipe. Downhole instruments are lowered in well via control head and long pipe string, forcing working agent via long pipe string is maintained under operating conditions while forcing via short pipe string is continued or terminated. In making technological jobs, inserted pipe is lowered in well via control head and long pipe string to stop forcing via long pipe string.
EFFECT: geophysical survey or technological jobs with lifting pipe string.
