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.

Matrix Bits are optimal solution for well drilling where use of ordinary steel bits lead to their rapid erosive wear.

Manufacturing a matrix bit body from a composite material based on tungsten carbide allows bits to drill in high abrasive formations using weighted drilling mud.

Specially selected material compositions provide high reliability and durability for continuous bit runs.Improved designing and manufacturing technologies make it possible to produce a wide range of drilling tools.

Matrix tools can be multiply subjected to restoration. This feature allows increasing life-time of tools and achieve higher rates.

Introduction:

Matrix Body PDC Drill Bit is suitable for medium hard and hard formations with optimized crown profile and cutters layout. It can achieve better performance in deep intervals. Long service life and high performance help reduce the drilling cost.

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

Technology

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

2.The formula of matrix powder: independent intellectual property rights and advanced sintering technology have made the mechanical properties of matrix reach the international advanced level. The blade of the matrix drill can be designed to be deeper and narrower. It can completely satisfy the complex drilling operation in the well.

One Matrix Body PDC Bit Drilled Successfully in Xujiahe Layer

in Sichuan China.

CHALLENGES

In order to reduce the quantity of PDC Bit drilling in Xujiahe Layer in the Sichuan of China. Chinese bit manufactures try to design enhanced PDC bit to drill by ONE BIT.

SOLUTION

Deepfast offer its own designed
Matrix Body PDC Bit 12 1/4 DF 1605BU to increase the lifetime of drilling bit.

RESULTS

It sets new Roprecord of 7.13

The bit drilled successfully in the layer by only One Bit

Overview

In the Sichuan of China. the formation is medium-hard but abrasive, Great Wall Drilling Company of CNPC try to increase drilling footage and reduce the quantity of PDC bits in Xujiahe Layer. In this layer, the depth is from 1300 to 1900 and the compress strength is 12000PSI-16000PS1. Deefast designs the Matrix Body PDC Bit 12 1/4″ DF1605BU for this project.

Technology Advantage

The Matrix Body PDC Bit 12 1/4″DF 1605BU is an improved bit specially developed for increasing the strength and lifetime of drill bits. The formula of matrix powder with independent intellectual property rights and advanced sintering technology have made the mechanical properties of matrix reach the international advanced level. Super strong material promotes gauge wear resistance to enhance long lifetime. It has the characteristics of high rotary speed stability and long service life while drilling.

Performance

It achieves best ROP of 10.61 m/h, and the average of ROP of five bits is 7.13 m/h.

All of bits drilled successfully in the layer by only One Bit.
