7 Choke Manifold Kill manifold A choke manifold is used to lower the pressured from the well head. It is necessary for controlling the well kick and implementing oil and gas well pressure. It consists of choke valves, gate valves, pipes, fittings, and pressure gauges. It is needed so that if one choke has to be taken out of service, the flow can be directed through another one. We manufacture 5 types of pressure grades: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa and specially customized accordance to the clients requested specifications. In case well head pressure releases, drilling fluid can be pumped through the down hole by the kill manifold to balance the bottomhole pressure so as to prevent well kick or blowout. In addition, the blowout pipelines connection can drain fluids from the well directly to release bottom-hole pressure. Cement can also be injected into the well through the kill manifold during the cementing operation as well as water or other agents can be injected when necessary. Check valves ensure that fluids flow in one direction through the down hole where no backflow occurs. The kill manifold consists of check valves, gate valves, pressure gauges and pipe lines. One end of it is connected to the drilling spool, and the other to the injection pump. Both choke manifold and kill manifold are made in conformity with API 16C standard. Xiongyue kill manifold has 5 classes of working pressure: 14MPa, 21MPa, 35MPa, 70MPa,105MPa. Rated pressure of all the pipe lines, gate valves and check valves must match that of the BOP. Kill manifold is not supposed to be used for regular drilling fluids injection.

For dual-face rant the upper and lower faces are symmetrical. For drilling tools in different sizes, only the semi-annular rubber sealing ring and the ram pressing block need to be replaced, and other parts are for common use. Single-face ram is not supposed to be used upside-down. Shearing ram will cut the drilling tool and seal up the wellhead. Variable bore ram is used to meet the demands of drilling tools in different sizes. Annular BOP 2) Ram Sealing Description Effective sealing of a wellhead depends on sealing in 4 different positions.i.e., sealing between upper side of ram and housing, sealing between front end of ram and the pipeline, sealing between side gate and housing, and sealing between piston rod and the side gate. 3) Ram Locking Operations By turning a hand wheel, the rams can be locked manually. But it can not be unlocked by the manual locking device. To unlock, be sure to reset the manual device, and then unlock the ram with hydraulic power. Operating principle A hydraulic control system is used to close or open the annular preventer. When used to close the BOP, high pressure oil is directed to the dosing chamber positioned at the lower side of the Piston, causing the piston to move upwards. The packing unit is compressed by the moving piston. Connected with the BOP top cover, the packing unit cannot move upwards and is forced to the center of the well to pack off a string or seal off the well. When opening the well the reverse valve of hydraulic control system is shifted, directing the high pressure oil into the opening chamber at the upper side of the piston to drive the piston downwards. The closing chamber will then recede, stopping the pressure on the packing unit allowing the well to open.
