During the test, the formation fluids must be directed to the separator and the burner after flowing through the drill pipe or tubing to the surface.This device is called a ground control device.It can safely and effectively control the liquid pressure and flow.
The control head is connected to the uppermost part of the test string, divided into two types of rotation and non-rotation.According to its bearing capacity can be divided into 35Mpa, 70Mpa and 105Mpa three.The control head allows both the high pressure fluid flow out of the column and the pumping of liquid into the well.
Used to control the liquid pressure, flow manifold.On the next control head, with the next separator, put the pipeline.
The rated working pressure of the drill pipe manifold is divided into 35Mpa, 70Mpa and 105Mpa.
High pressure active manifold for connection of control head, drill pipe and discharge line.It consists of a special thickening of seamless steel pipe by the elbow and activities of elbow composition.Manifold working pressure is divided into 35Mpa, 70Mpa and 105Mpa.
Activities manifold to regularly check, lubricate, replace the seal and the hydraulic seal inspection, to ensure the safety test.
