SYSTEM FOR DISENGAGEMENT OF TWO WELL OBJECTS AND METHOD SETTING UP AND OPERATING SAID SYSTEM

FIELD: oil extractive industry, namely, system for disengagement of two well objects and method for mounting and jointly-separately operating it. ^ SUBSTANCE: device contains packer, valve devices, including bodies and latches for axial movement. Packer is mounted between valve devices, upper and lower one, respectively, each of them forming functional channels. Auxiliary equipment, for example, sleeve-less pipes column, is connected to functional channel of upper valve device. Lifting column of tubing string is connected by means of disconnector, positioned above upper valve device, to functional channel of lower valve device, forming functional channels for joint-separate interaction, respectively. Input the body of upper well device a collet is made with leaves and extractible insert positioned inside, combined with latch for axial movement of this device and holding extractible insert by leaves until their mating with recess made in aforementioned body. Axial movement latches of upper and lower well devices are connected by, for example, synchronizer, mounted in the packer. In accordance to method, device is launched when lower valve device is closed and upper valve device is open. System is set up above lower object. Packer is unpacked, by means of disconnector tubing string is detached from system and auxiliary equipment is suspended on crosspiece, for example, sleeve-less pipes column, thereby connecting it to functional channel of upper valve device. Upper object is inspected. Then, catcher is lowered into upper valve device for catching extractible insert, held by collet leaves, catcher is raised with extractible insert until leaves engage with recess made in the body of aforementioned valve device, catcher with extractible insert is raised, providing for opposite change of position of axial movement latches of upper and lower valve devices for inspection of lower object. ^ EFFECT: increased safety of oil extraction from fountain well due to separate extraction of oil from objects. ^ 2 cl, 7 dwg
