Product Introduction：Surface test tree, also called flow head, is located at the top of the test string to contact, test and control the oil well output. It is used to support the test string, and to facilitate and control the flow of the fluid medium into or out of the well. The wing valve is usually equipped with a fail-close actuator which is link to the emergency shutdown system, this configuration allows for remote shut-in of the well on the surface. The kill wing valve is a manual valve and should remain open during testing operation to allow immediate killing of the well. Swab valve is usually a manual valve too and can perform live well intervention operation during test or production. The handling sub attached to the top of the flow head provides an interface to the surface wireline or coiled tubing equipment. The swivel connects all kinds of fluid pipelines, allowing rotation of the string without rotating the flow head.The master valve is located below the swivel, and can be used when the valve in the swivel is leaking.
