Ground rotation test tree

The surface rotary test tree (flow control head) is the main equipment for controlling oil and gas wells and running cables;

1. Equipment such as blowout preventer and blowout preventer connected with cable and steel wire at the upper part;
2. The lower part is connected with drill pipe or oil pipe;
3. The flow head is usually equipped with a rotary nipple to rotate the lower string, such as setting the packer;
4. Hang the lifting nipple with the lifting ring of the drilling crew to hang the control head;
5. There are four gate valves arranged in a cross shape;
6. The main valve is a manual valve at the lower part, which is used to isolate the oil well and the surface flow;
7. The suction valve is a manual valve at the upper part, which is used to run the cable tools into the wellbore;
8. The flow wing valve is a hydraulic fault free normally closed valve, which is pressurized and opened through the control panel, and can be quickly shut in in case of emergency;
9. The kill wing valve is a manual valve, which is connected to the pump truck through a single flow valve during testing, and is used to kill the well in emergency;
