6 FAQs about [Balancing valve block for down-the-hole drilling rig]

What is a drill pipe float valve?

High-performance drill pipe float valves are crucial for consistent fluid control throughout the drilling process. Also known as non-return valves, this type of down hole valve prevents undesirable fluids from backing up into the drill string any time the drilling crew is making or breaking connections.

What is a downhole deployment valve?

This allows the valve and tieback string to be easily retrieved when drilling ends. The downhole deployment valve is typically set at a depth below the mudline, but placement is flexible and can be as deep as the well plan requires. (Photos courtesy Weatherford)

What are the different types of drill pipe valves?

The chapter also covers the use of downhole motors in UBD, snub-bing units, air hammers, special equipment used in gaseated mud systems, drill bits, and measurement-while-drilling (MWD) systems. Drill pipe valves include bit floats, string floats, re-trievable floats, inside blowout preventers (IBOPs), lower kelly valves, and deployment valves.

What is the difference between underbalanced drilling and well control?

B-1 Underbalanced drilling (UBD) and well control are simi-lar technologies. That is, the well is shut in against pressure in the wellbore and the well is circulated through a choke (fig. 1.1). Thus, the basic concepts of pressure in well control are also basic to UBD.

What are the different types of drill string valves?

Houston Downhole furnishes several types of Drill String Valves. All are API Spec 7.1 Certified. They are built and pressure tested to all API 7-1 specifications. Kelly Valves, Safety Valves, Inside BOP Valves and Drop-In Check Valves are all used to control the fluid flow thru the ID of the drill string.

What are the different types of rig valves?

The valve locks down the flow of fluids while the crew at the rig floor are making or breaking connections. Finding the best fit for every individual project is important, and the different types go beyond just the split between the F-type plunger valves and the G-type flapper valves.
