The Hole Opener comes in handy when the drilling operation needs to increase the diameter of the hole. For example, in oil production, in some cases it is necessary to run a larger diameter casing, which requires reaming the drilled hole. It can expand the original small drill hole to meet the needs of subsequent engineering size, for subsequent mining equipment installation, cementing and other operations to create good conditions. Moreover, in some geological exploration projects, it is necessary to obtain a larger diameter core sample, and Hole Opener can also meet this special need.
1.vigor hole opener material and advantages
Vigor's products are manufactured in fully heat-treated alloy steel and can be equipped with carbide grinding and insert tools to withstand harsh downhole conditions.
Benefits Vigor's oilfield products are downhole tools designed for precision borehole enlargement in a variety of drilling and completion applications. They use the cutting structure on the blade or cone to wear the wellbore and increase the diameter of the wellbore beyond the size of the pilot bit, and their arms and cutters are hard-faced designs that provide three different types of protection against different conditions and rock formations. It is designed to allow replacement of cutters.
2.vigor hole opener type and size
Depending on formation conditions and the diameter of the reaming target, it is important to select the right type of Hole Opener. If the formation is hard but the reamer is selected for soft formation, it may lead to excessive tool wear, low reaming efficiency and even can not complete the reaming task. At the same time, the selection of dimensions should be precise, taking into account the match between the aperture after reaming and the size required for subsequent operations.
Vigor has many different types to meet the various applications. The Max. size can be 36".Special size is also available with detailed well conditions. the following table includes some required standard sizes. Vigor can provide most sizes on request.

3.Why choose VIGOR hole opener?
Precision control: Electronics on the tool and surface instruments can closely monitor and control the well diameter. This can be scaled up precisely to the planned size.
Improved efficiency: compared with conventional reaming, the optimized cutting structure has a faster opening speed and lower torque and vibration. This reduces drilling time and costs.
Risk minimization: The increase in a single run minimizes the risk of unstable formations. Real-time downhole weight telemetry prevents damage.
- Versatility: It is designed for a variety of hole conditions, hole sizes, casing types, reservoir pressures and formation strengths.
- Durability: Strong sealing system, wear-resistant tools and high-strength materials ensure reliable performance and long service life.
