INSTALLATION injection liquid in the lower reservoir and OIL RESERVOIR OF UPPER

摘要

The proposal refers to the art and technology of simultaneous selection of products from a single reservoir and pumping of liquid in another well layer. Installation for pumping fluid into the lower reservoir and oil from the upper reservoir comprises a downhole tubing string and a packer arranged between the lower and upper layers. A packer disposed at the bottom end of the pipe string and is designed as a double-folding of the elastic sleeve. Outside the pipe string above the upper layer is equipped with additional packer designed as a self-sealing cuff impermeable downward. Inside the pipe string above the upper layer is provided with a flow distributor with two through channels, one of which is vertical, and the other rotary. Inside the pipe string opposite the upper reservoir is mounted the hollow rod whose upper end is housed in the through pivot passage and hermetically inserted into a lower transverse wall formed in the pipe string between the upper and lower layers. The inner space of the pipe string communicated vertical through bore of the flow distributor and holes made in the pipe string to the upper reservoir and the annulus tubing string above the packer further communicated through channel rotary flow distributor and the interior of the hollow rod and the perforations of the shank with the lower reservoir. The discharge valve is installed in the liner above the perforations. The proposed apparatus for pumping fluid into the lower reservoir and oil from the upper reservoir has a simple structure, in addition, the deep execution pump is installed directly in the range of an oil well formation that allows to increase its efficiency, and simultaneous selection of products from a reservoir and pumped liquid in another well layer You can increase the installation possibilities. 1 Fig. to 1 liter.
