Development Trend and Prospect of PDC Drill Bit Technology

Ⅰ. Comprehensive analysis of the development trend of PDC rock bit technology

1. The formation adaptability is stronger. The underground formation and lithology are complex and changeable, and may even encounter high temperature and high pressure layers. In order to reduce the times of drilling, it is necessary to continuously enhance the formation adaptability of the PDC rock bit and enhance the high temperature and high pressure resistance of the PDC rock bit.

2. Drill faster. Speed-up is the eternal theme of drilling, and it is also the most effective way to reduce drilling costs. The speed-up of PDC rock bits is endless.

3. Longer life. It's not enough for pdc drill bit to drill fast, it must have a long life to ensure long footage in one downhole.

4. It is easier to guide. More and more horizontal well applications have put forward higher requirements for the steerability of PDC rock bits.

5. The unit footage cost is lower. The pdc drill bit is not the more expensive the better, the pdc drill bit with low cost per footage is the good pdc drill bit.

6. Be smarter. In order to measure the working condition of PDC rock bit, detect the geological and engineering parameters of bottom hole, many PDC rock bit manufacturers are developing instrumented PDC rock bit and intelligent PDC rock bit.

Ⅱ. The market share of pdc drill bits will further expand

At present, in the two major drilling markets of the United States and China, the drilling footage of PDC rock bits accounts for more than 85% of the total annual drilling footage, and there is still room for growth in the future share.

In the next 5 to 10 years, the drilling footage of PDC rock bits will account for more than 90% of the global annual total drilling footage.

High-tech continues to optimize the design and manufacture of pdc drill bits, accelerating integration innovation and disruptive innovation. High-tech such as big data, cloud computing, 3D printing, virtual reality, artificial intelligence, etc., will be increasingly introduced into the optimal design, manufacture and selection of pdc drill bits, accelerating the development of personalized pdc drill bits.

The application of these new technologies will further accelerate the integration innovation and subversive innovation of pdc drill bits, and promote the individualization, diversification and integration of pdc drill bit cutters and pdc drill bit structures.

Ⅲ. The intelligent PDC rock bit will better guide the PDC rock bit to improve the ROP

Looking forward to the future, the intelligent PDC rock bit with its own sensor can directly measure the working condition of the PDC rock bit, bottom hole geology and engineering parameters, which is beneficial to:

(1) Better guide the PDC rock bit to drill in the sweet spot, and improve the drilling encounter rate of the reservoir;

(2) Adjust the drilling engineering parameters in time to minimize the vibration and gyration of the PDC rock bit, improve the working condition of the PDC rock bit, increase the ROP, and prolong the service life of the PDC rock bit;

(3) Accurately judge the wear of the PDC rock bit and choose the best tripping time.

Ⅳ. High-tech materials to create a new generation of pdc drill bits

The world is setting off a graphene research upsurge, and China has become a leader in graphene research. Graphene will bring about a material revolution, profoundly affecting all aspects of human life and production.
