Ground rotation test tree
The ground rotating 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 for upper connection of cable and steel wire operation;
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 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 cross shape;
6. The main valve is a manual valve at the lower part, which is used to isolate the well and surface flow;
7. The suction valve is a manual valve located at the upper part, which is used to run the cable tools into the wellbore;
8. The flow wing valve is a hydraulically controlled fault free normally closed valve, which is pressurized and opened through the control panel to release pressure and shut in the well quickly in case of emergency;
9. The kill wing valve is a manual valve, which is connected with the pump truck through a single flow valve during the test, and is used for well killing in case of emergency;
