Equipment for simultaneous-separate production and injection with sucker rod pump
1. Injection wells with oil-saturated formations;
2. Production wells with injection potential.
1 – Packing box;
2 – Blowout preventer (BOP);
3,4,5 - Manometers;
6 - Shut-off valve.
Production and injected reservoirs are separated by a packer. A sucker-rod pumping unit with a tubular pump withdraws fluid from a productive formation through a tubing string of smaller diameter. The agent is injected into the injected formation from the wellhead through the annulus between the tubing strings of larger and smaller diameters.
