• Air-hammer Rotary Drilling: This uses compressed air both to drive the drill, with a rotating hammer action, and to carry the cuttings to the surface. Temporary steel casing can be driven, i.e. hammered through the soft soils overlying the bedrock, but hammering casing into place may mean that the casing cannot easily be withdrawn after it has served the purpose of supporting the unstable

Rotary Drilling Hose Used for Oil Fields

Rotary drilling hose is mainly used for conveying water-based or oil-based mud and other fluids in the working temperature of -30 °C to +82 °C. It is often used for oil fields, cement repairing, geological exploration and water conveyance for coal excavation. It is composed of three parts: tube, reinforcement and cover. The tube is made from NBR, which is resistant to abrasion, corrosion and

Rotary Drilling - an overview | ScienceDirect Topics

In rotary drilling operation, the hydraulic system consists of stand pipe, rotary hose, swivel, kelly, drillpipe, drill collar, drill bit, and the annulus. The mud pump discharges the drilling fluid which passes through the surface lines and hydraulic system. The mud begins to travel downward through the drillpipe and drill collars and is expelled through the nozzles of the bit and return up

Kelly hose - Wikipedia

A Kelly hose (also known as a mud hose or rotary hose) is a flexible, steel reinforced, high pressure hose that connects the standpipe to the kelly (or more specifically to the goose-neck on the swivel above the kelly) and allows free vertical movement of the kelly while facilitating the flow of drilling fluid through the system and down the drill string.

What is Rotary Hose For? - Oilfield Drilling Equipment

A rotary hose is used in oil well drilling. It acts as the crucial instrument in the connection being made between the standpipe and the swivel. A rotary hose is also used as a means of permitting the kelly to be either raised or lowered through the drilling process while also allowing the drill bit to be raised with the drillstring. For this reason, it is also often referred to as a “kelly
