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.

Drilling in extremely hard formations It is suitable for coring in extremely hard abrasive formations, such as sandstone.

Features

◆Curved crown
The curved crown has a smooth core

◆Radiant waterway design
The bit has radiant waterway design which is suitable for high speed.

Technology

◆The self-sharpening impregnated insert
The self-sharpening impregnated insert keeps the cutting sharp during drilling.

◆The unique matrix formula
The unique matrix formula makes the matrix match the wear and formation,optimizes the cutting

Introduction:

It is suitable for coring in extremely hard abrasive formations, such as sandstone.

Features

1.Curved crown: The curved crown has a smooth core

2.The self-sharpening impregnated insert: The self-sharpening impregnated insert keeps the cutting sharp during drilling.

3.The unique matrix formula: The unique matrix formula makes the matrix match the wear and formation, optimizes the cutting edge and wear resistance of diamond which makes the bit obtain a better ROP.

Impregnated Core Bit Complete Core Service

in Extremely Hard and Deep Formation

CHALLENGES

Extremely hard and abrasive formation

The depth is about 4,000 meters

Request for high recovery rate

SOLUTION

In order to solve these problems, DeepFast offers Impregnated Core Bit 8 1/2” x 4” DIC280 to achieve this goal in deep and hard formation.

RESULTS

With the core cut 1 15 meters in two runs. which is from 3805 to 3920 meters

The coring time is about 20 hours, and ROPIS 5.75 m/h

The recovery rate is more than 85%

Overview

In the Liaohe Oilfield in China, the operator Liaohe Oilfield Coring Technology Services planned to drilling in the deep well of 3805 meters. The formation is extremely hard and lithology is granite with the compress strength more than 24000PSL. Its objective was to core the 8 1/2” hole section of the well to recover the hard formation. The normal PDC core bit had only low recover rate and less core cut. Therefore Deepfast offers its new designed Impregnated Core Bit to achieve this goal in deep and hard formation.
