Ranking is hole opener manufacturer that offers four types of hole opener: HDD rock reamer, repalce hole opener, vertical hole openers. Our hole opener factory in China produces 200mm hole openers for low-pressure applications. Ranking is also a supplier of Milled Teeth Hole Openers and Custom-Built Hole Openers.
Hole openers are 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 8 inches to above 66 inches. Usages range from Vertical Drilling to Horizontal Directional Drilling（HDD) & Back Pulling Drilling
This article provides a guide to hole openers. It discusses the advantages and disadvantages of each type, applications, and factors to consider when purchasing, as well as the different types of hole openers(rock reamers) on the market. Finally, this guide will help you compare TCI Hole Openers/HDD Reamers with other types of hole openers or Rock reamers.
Also known as rock reamers, hole openers are used to enlarge the existing hole by cutting into the rock. Applications of hole openers include:
The working principle of hole openers is that when the hole opener rotates, the TCI palm cutter also relies on pressure to rotate, so the TCI palm cutter can form a concentric network crushing trajectory when breaking the rock at the working face, during which the rock is squeezed into thin layers of fragments to fall off.
TCI hole openers are ideal for jobs where trenching is not possible, such as pipe installation.
TCI Hole Opener can be customized to any size to meet engineering requirements.
For vertical directional drilling, the cost of a hole opener is 2-3 times lower than a larger size tricone bit.
Good effect of shoring and slag removal, reduce the repeated rock breaking of TCI cutter and improve the reaming speed
TCI hole opener is mainly used for reaming hard rock sections, and its effect is better than barrel reamer.
For vertical directional drilling, the cost of a hole opener is 2-3 times lower than a larger size tricone bit.
The Diameter of Hole Opener is the first factor to be considered by the customer. Tell your supplier the size of the hole to be reamed each time to design the most suitable hole opener for the project and save money.
If you are unsure of what size to purchase, consult your supplier. We will be able to provide you with specific recommendations based on the specifications of your project.
Reamers are available in sizes from 8″ – 66″, or larger. We specialize in customizing them for you.
The size of the hole opener is determined by the size of the pilot hole. When choosing a hole opener, the size of the pilot hole must also be taken into account, as it determines the size and number of teeth to be used in the hole opener.
When selecting a hole opener, you can provide the supplier with a description of the formation, e.g. soft to medium formations with medium soft, low compressive strength and interbedded. Rock type, e.g. mudstone, chert, hard gypsum, shale, etc. Or tell us what is the compressive strength in MPa. Based on the information you provide, we will professionally provide you with the most cost effective reamer that suits your needs. The recommended solutions for the hardness of the formation are as follows: chisel tooth , IADC537, is recommended for medium hard and soft formations; tapered tooth, IADC637, is recommended for harder formations. ball tooth, IADC737, is recommended for hard formations. the correct tooth palm shape will increase drilling speed and save costs.
If you choose a custom hole opener, you will be required to provide the type of thread to better match the drill rig and the drill pipe, e.g. if you are using a Ditch Witch drill rig, you will need to choose a thread starting with JT. We also provide API standard snap type, for example: 4 1/2 API REG.
Most important, please let your supplier know the type of well you want to drill: Trenchless(Horizontal Directional Drilling) or Vertical Directional. We will provide you with a professional customized service.
The size of the roller cone is determined by the size of the pilot hole and the size of the hole opener. The smaller the roller cone size used, the lower cost of the hole openers and the smaller the expanding area. Oppositely, the larger the palm size, the higher the cost of the reamer, but the larger the area that can be reamed.
The layout of the number of roller cone is related to the hardness of the formation and the desired for drilling speed. The harder the formation, the closer the number of palms, the slower the drilling speed and the poorer the chip evacuation capacity. When the formation is medium-hard or soft, the number of roller cone can be slightly sparse, which can increase the drilling speed and improve the chip removal capacity.
The diameter of the center rod is related to the layout of the roller cutters, and the length of the center rod of the hole opener is related to the torque force that the reamer can withstand. The greater the length, the greater the torque. To prevent the center rod from breaking due to excessive torque. Please consult your supplier and we will provide you with professional advice on the length.
