6 FAQs about [Hydraulic system design of down-the-hole drilling rig]

What is a down the hole drilling rig?

Down the hole drilling rig is an impact rotary drilling rig. Its internal structure is different from that of a general rock drill.

What is a horizontal directional drill rig?

Horizontal directional drill rigs are developing towards large-scale, micro-miniaturization, mechanical automation, hard stratum working, exceeding length and depth oriented monitored drilling. Measuring the inclination of a wellbore (its deviation from the vertical) is comparatively simple, requiring only a pendulum.

What is a hydraulic rotary drilling rig?

A hydraulic rotary drilling rig is a type of drilling rig used primarily in the construction of sandy soil, cohesive soil, and silty soil, as well as other soil layers. It is used for the construction of cast-in-place piles, continuous walls, foundation reinforcement, and other foundations.

What is the purpose of drilling hydraulics in a well?

The drilling hydraulics system serves many purposes in the well. Since it is centered around the drilling mud circulating system, the purposes of mud and hydraulics are often common to each other. The hydraulics system has many effects on the well. Therefore, the reasons for giving attention to drilling hydraulics are abundant.

How drilling hydraulics affect drilling performance?

Working in the oil field and loving to share knowledge. Drilling hydraulics affect directly drilling performance and this topic will focus on the basic principle of the drilling hydraulics as Circulation System on Drilling Rigs, Frictional Pressure Loss and Advantages of drilling hydraulics.

How does a rig circulation system work?

Typically, the rig circulation system is composed of mud pumps which deliver drilling mud from mud pits to hoses and pipes down to the bottom of the hole. Drilling mud is moved through a bit into the annulus and is finally returned back to solid control equipment and the mud pits (you can see from the following diagram). Frictional Pressure Loss
