Work Process and Simulation of Cone-Type Hole Opener

 



Work Process and  Simulation of Cone-Type Hole Opener

Having a broad understanding of the operation of Hole Opener gives you a control over it. The first video gives you an idea on how this tool functions.

During the design process of Hole Opener, just like in most tools, thorough design analyses are carried out. The basic idea behind these analyses is to ensure that both the tool components and the environmental factors are put into proper consideration.

For the tool components, material selection and other design parameter are given proper attention. Proper materials are selected to match the design requirement. Modal and Parametric Analyses are carried out to evaluate the best size of material that can ensure safety and the same time cut down on cost.
The Second video gives you an idea of Modal Analysis.

Cone-Type Hole Opener

Overview
Cone-Type Hole Openers are designed  for the demanding drilling environments throughout the world.
The tool is normally used in conjunction with a roller cone-type bit with a cutting structure matching the hole opener or run with a bull nose for cleanout operations.
Cone-Type Hole Opener is manufactured from high quality steels.

Applications

A hole opener is a device used to enlarge the borehole during a well drilling operation. It can be positioned either above the drill bit or above a pilot run inside the existing borehole.

Numerous designs exist, in sizes varying from a couple of inches to above 50". Usages range from hydrocarbon drilling operations to water drilling or horizontal drilling.

Hole opener arms have to sustain heavy loads during operations and are generally made of high-grade alloy steel, welded onto a solid alloy steel body. Some designs feature replaceable arms, allowing for size changes but decreasing overall robustness.
