TD40 - 115F8A Drill Bit: Rototec's Geothermal Well Project

1. Project overview

The project is the Rototec Geothermal Well Project, which was carried out from Sept 10 to Oct 15, 2024 in Tiilimäenkatu, Lahti, Finland. The aim of the geothermal well project is to explore and develop geothermal energy resources and to contribute to sustainable energy use in the area.

2. Construction environment

The geological formations at the construction site consist mainly of hard wearing granite and gneiss. The working air pressure is 35 bar and the rotational speed of the drill pipe is 100 - 120 r/m. Drilling in such hard rock formations places high demands on the drill bits and requires high performance drilling tools to ensure efficient and stable operation.

3. Product Description

• Fast drilling speed: The unique design and high quality materials of the TD40 - 115F8A drill bit enable it to break hard granite and gneiss quickly. This greatly improves overall drilling efficiency and reduces the time and cost required for projects.
• High abrasion resistance: The TD40 - 115F8A drill bit is made of advanced abrasion-resistant materials that can withstand the intense friction and impacts of drilling in hard rock. This ensures that the drill bit maintains its cutting ability over a long period of time without noticeable wear, reducing the frequency of bit replacement.
• Long service life: The combination of high wear resistance and robust structural design gives the bit a long service life. This not only saves the cost of frequent bit replacements, but also minimizes downtime during construction, ensuring that projects run smoothly.

4. Project Implementation

During construction, the bit performed well despite the challenges of hard geological conditions such as granite and gneiss. With an operating air pressure of 35 bar and a rotary speed of 100 - 120 rpm, the bit penetrated the rock quickly. Its fast break-up and drilling speed enabled the team to complete the geothermal wells within the planned timeframe. The high wear resistance and long life of the drill bits also reduced the number of bit replacements, ensuring continuous operation of the drilling equipment and improving the overall efficiency of the project.

5. Customer Evaluation

In addition to Wontech brand drill bits, customers have also experienced Products of other brands. After comparing the performance of different products, they were very satisfied with the TD40 - 115F8A drill bit. Customers were impressed by the bit's outstanding performance in terms of breakout speed, drilling speed, wear resistance and service life. This positive assessment reflects the high quality and reliability of the bit, making it ideal for drilling projects in geothermal wells in hard rock formations.

Overall, the successful case of the TD40-115F8A bits in Rototec's geothermal well program demonstrates its outstanding performance. It provides a reliable solution for drilling operations in hard geological environments and contributes to the successful implementation of geothermal energy projects.
