INSTALLATION FOR SIMULTANEOUS SEPARATE WATER PUMPING INTO RESERVOIRS

摘要

FIELD: gas and oil production. ^ SUBSTANCE: installation consists of production tubing with packers dividing reservoirs and with couplings with axial and radial channels and of removable plug. The removable plug is lowered from a wellhead on a rod and pressure tightly interacts with axial channels of the couplings. The installation has lengthwise channels communicating spaces above and under each starting clutch. The removable plug is complex and consists of plungers connected with rods and interacting with axial channels of the couplings corresponding to them. The plungers are constantly located in the well. The lengthwise channels are made in each plunger, while couplings are made in form of polished bushes with radial orifices. Also, length of rods, bushes of couplings and plungers as well, as their number and orifices in the bushes of the couplings are chosen to facilitate selective shutting of radial channels with the plungers in corresponding bushes of the couplings without extraction of the plug to surface. ^ EFFECT: raised efficiency of measurement and control of volume of water pumped into reservoirs both simultaneously and separately. ^ 3 dwg
