SYSTEM RESERVOIR-razor

摘要

The system is designed to cut off the operation of the reservoir wells. The system is run on the drill string 1, consisting of the upper 2 and lower 3 columns. The system comprises a packer 4, the pump 5, 6 disconnector nipple 7, the valve block 8, the installation tool (withdrawal) of the valve block 17, catcher 8 and solids 21. The disconnector 6 is disposed above the packer 4 arranged on the bottom of the pipe string 3 in the form of the shank. Outer tubing string 2 response disconnector 6, which allows for its replacement. The valve unit 8 includes a safety valve 9 with the housing 10 and the locking element 12 and locking device 13 with the gripper 14 and the locking collet 15, a spring-loaded safety valve with respect to the axis 9. The valve unit 8 is installed in nipple 7. Valve housing 10 is sealed clipper 9 7 with respect to the pin 11. The installation of the valve seal unit 8 in the pin 7 is performed using the tool 17 with the mounting Yassa collet 18 and 20. The safety device 21 is installed in the borehole after the lift device 17 and the subsequent lifting of the upper column tr K 2 but before the shutter pump 5. The safety device 21 is designed as a pipe with openings 23 and 24 and the baffle 22 located above the disconnect switch 6. The technical solution of the system increases the reliability of the installation and operation of the downhole equipment, 4 nc f ly-5-yl.
