Design for higher ROP in drilling deeper and harder formations, PDC drill bit always drills from ground to bottom directly with less or even a single run, saving large amount of drill time and cost .

Differ from tricone bit, PDC drill bit runs with lower WOB but Higher RPM, so it usually works with downhole motor to pick up rotating speed.

The performance of PDC drill bit depends a lot on PDC cutters, we provide unique solution to specific requirement on varied formations.

Introduction:

Steel Body PDC Drill Bit obtains better ROP in soft to medium hard formations and lower compressive strength.

Features

1.Durasef Gauge: Super strong material promotes gauge wear resistance to enhance long lifetime.

2.Hydraulics: The movement and cooling of cuttings can be optimized by the hydraulic design that matches the chip quantity and displacement of each blade.

3.Special Backrake Design: A Backrake can be added in the bit in order to prevent the bit from getting stuck when drilling.

Technology

1.Unique Blade Design: Importing exclusive cutting teeth and unique curved blade design improve the ability of drilling in hard interlayer.

Steel Body PDC Bits Set ROP Records While Drilling  

in Sichuan China.

CHALLENGES

In order to reduce the cost of imported PDC Bit from Smith and Halliburton, Chinese manufacture offer their own designed PDC Bit for well drilling to replace Smith Bits.

SOLUTION

In order to achieve better ROP, DeepFast offer its own designed Steel Body PDC Bit 12 1/4″ DFS1905U to obtain higher ROP.

RESULTS

It sets new ROP record of 22.18 m/h.

It has better ROP than Smith Bit and Halliburton in this area.

Overview

In the Sichuan of China the formation is medium-hard but abrasive, Chuanqing West Drilling Company would like to improve drilling speed and it specially carry out PDC tests in SI005-X5 and $I005-X6 wells starting drilling from about 500 meters for 12 1/4 hole. Deefast designs the Steel Body PDC Bit 12 1/4″DFS1905U for this project.

Technology Advantage

The Steel Body PDC Bit 12 1/4” DFS1905U is an improved bit specially developed for stability and high performance. With the advanced PDC cutter and unique blade design, it has improved the stability while drilling. This bit has preventing bit sticking technology, Gauge enhancement technology and adopts high-performance PDC Cutters. It has the characteristics of high rotary speed, stable operation and long service life while drilling

Performance

It sets new ROP record of 22.18 m/h, and the average of ROP of five bits is 17.27m/h.

It has better ROP than Smith Bit and Halliburton in this area.
