INSTALLATION for simultaneous separate injection and production from multizone via one well

摘要

The invention relates to the petroleum industry, namely, to develop a multizone via one well.; Solvable invention challenge and the expected result is to increase efficiency of the plant to simultaneously separate injection and extraction of the multizone through one well and allowing the advancing commissioning unused layers without special drilling additional wells.; Installation for simultaneously separate injection and extraction of the multizone via one well, comprising an injection pipe string with a packer deflated to the lower layer, and extracting tubing string deflated to the upper layer, characterized in that the production pipe string is equipped with a pumping unit and deep pump and is arranged parallel beside the injection pipe string.; Application installation is especially important for the effective development of small multilayer oil and gas fields with a limited fund of wells and local arrangement of individual layers of the reservoir.
