Suzhou Energy Tool 8-1/2” MT516 EA033 Drill Bit Usage
First . Basic data of oil well
1. User: Jiangsu Oilfield 32650 Drilling Team
2. Use hash marks: Yong 7 and 8 wells
3. Well type: horizontal well
4. Location: Yong'an Town, Jiangdu City, Jiangsu Province
5. Design depth: 3173M
Second. Basic data of drill
Drill bit specification: 215.9mm MT516
Gauge length: 40mm
Third . Drill bit usage and out-of-well analysis
2019.6.9 The company's drill bit was used by our team, and the well was drilled at a depth of 1300M to 6.14 days
Drilling out at 12:30, drilling to 2500M, and exiting the well at 21:50.
The mechanical speed before passing through the interlayer: 28M/hour or more, the turntable speed is 55 rpm,
The screw speed is 120r/m, and the footage reaches 1200 meters, which passes through several interlayers,
After the drill is lifted out, there are several composite pieces that are normal wear and tear.
The overall fineness is 80%, which is faster than the same model PDC drill bit.
Fourth . Bit comparison and evaluation
1. Data comparison: Jianghan's drill bit average speed is 10.5m/h in Yong'an block, Suzhou Energy drill bit ,the average speed is 12.45m/h.
2 .Drill bit evaluation:
- To meet drilling needs, the bit structure is suitable for the use of drilling tools
b. Compared with the same type of drill bit, the machine speed has certain advantages:
c. The company is one hour away from our well team to communicate with each other and improve the PDC bit And for convenience.
- All drilling parameters are normal and can be recommended for promotion.
Fifth . Drill recommendations and improvements.
It is hoped that manufacturers will further improve the aggressiveness of PDC drill bits and abrasion resistance to adapt to a variety of complex formations.
Sixth . See the pictures before and after the use of the PDC bit
