DEVICE FOR REGULATING THE SELECTION liquid during operation of wells

摘要

The proposal finds application in the extraction of oil from wells with simultaneous operation of the two reservoirs. It simplifies the design and provides high operability. The essence of the proposal. The apparatus includes a setting tool, a packer and a regulating unit. A feature of the device is that as a regulating unit uses differential valve fixedly mounted in the sleeve inside the thrust nozzle setting tool. Shut-off valve body is biased downward, while its body is provided with radial channels communicating with the inner space of the wellbore device.
