Product Detail

Product Tags

The drilling manifold an important equipment in Ou Gas) drilling circutation system. It pumps high-pressure mud into the well, clean well bottom, carries debris, and complete the drilling fluid circulation.

The drilling fluid manifold is composed of hard seal mud gate valves, high pressure spherical unions,high pressure gauges, short joints, etc.The ground manifold has features of compact structure and lower hydraulic resistance. The Rig floor manifold adopt reducing crosses, which is convenient of single standpipe/double standpipe.

M series modular drilling fluid manifold is of high compressive strength,high safety ,long service lift and modular design and manufacture shorten time of installation and disassembly time.

Main Technical Features

Drilling-Manifold02

1. The whole set of drilling fluid pipe assembly products are designed and manufactured according to the four modules of Derrick rise, drilling platform gate valve group, ground pipeline and ground gate valve, to realize modularization, to improve the efficiency of assembly of on-site pipes, and to shorten the installation.

2. The control gate valve adopts new design of anti-sand setting, flexlble switch and small torque, which solves the blockage of gate valve.

3. Pressure bearing parts made of high strength alloy and automatic welding, improve the strength and service life.

Choke Manifold

When drilling fluid in wellbore is polluted by stratigraphic liquid, will break the balance between the hydrostatic column pressure of drilling fluid and the pressure of stratigraphic liquid, resulting in overflow and blowout. When the blowout preventer is closed, the throttle valves’opening or closing can control the back pressure to maintain a certain bottom well pressure, so as to circulate out the polluted drilling fluid or pump in to new drilling fluid.

Kill Manifold

Main Technical Features

1. The choke manifold is applied to control overflow blowout and pressure of oil-gas wells.
2. When the wellbore is fully sealed by blind Ram, kill operation is carried out by forcibly pump heavy mud to the wellbore through kill manifold.

Fracturing Manifold

On the premise of ensuring mechanical properties, optimize critcal dimension and reduce the weight of the fracturing manifold; optimize material of body and increase the internal diameter of the fracturing manifold elements. Special process for elbow inner surface improves inner core strength and the outer core ductility; floating seal plug valve with split stem and cock makes reliable sealing and long service life.

Drilling-Manifold005

Main Technical Features

The pipe are treated with self tightening technology to make the internal side of the pipe bears compression prevent the fatigue crack from expanding.

Increase the internal diameter of the pipe fittings to reduce weight and adapt to large displacement operation.

Lateral tees and T-tees are adopted with integral forging process to achieve high strength and long service life

The internal surface of lateral tees and T-tees adopt shot blasting technology, achieved higher anti-fatigue strengthening factor and surface anti-scour ability.

Chiksan adopt ladder roller path design, increase thickness and rotation flexibility of the hinged area.

Plug valve is designed with floating valve core bi-directional sealing, which makes balanced loading on sealing arcs and small torque.

The fracturing manifold is designed with eight annular inlets which reduces the volume of manifold assembly, and features convenient transportation and quick operation.
