Product Description

The optimization GM1318 has proven to increase bit performance across a range of medium formations and operating parameters.

Bit Specification

The Production Process of Matrix Body PDC Bit

Features

Advanced tungsten carbide material matrix body 20% improvement in erosion resistant than precious matrix bit Less cutting structure less and bit body damage Provide multiple advantages in interbeded lithology. Enhanced bit stability for BHA shock and vibration mitigation. Increase cleaning and reduce balling. Superior PDC cutter technology made a perfect performance on impact strength resistance and abrasive resistance. Dual row cutter extend the aggressiveness and durability. The FEA software for the cutters distribution and layout made the drilling more efficient and reduce NPT. Optimize the angle of the cutter in both axial and radial by FBS(force balance analyze) software resulting in stronger aggressive and more durability of the bit. DOC(depth of cutters) was calculated and optimized by a series experiences of the bit,made the cutter penetrate the formations more rationally.

Option Features

Gauge length

Short：Improved bit steerability and tool face control for directional or horizontal drilling, reduce slide section by achieve builds more quickly.

Extend：Enhances bit stability and allows more area for gauge protection components, improves bole hole quality.

Active gauge

Protect the gauge and improved hole quality

PDC Cutters

Different features of PDC cutters can be chosen in different wells or formations for both drill efficiency and economic

Drilling Reports

Use special drilling tools (PDC bit or Tricone bit, drilling tool) to break up the rock in the stratum to form a well and reach the target layer, which is drilling.

About Drilling:

1. Use special drilling tools (PDC bit or Tricone bit, drilling tool) to break up the rock in the stratum to form a well and reach the target layer, which is drilling.

In general:

The well depth within 1500 meters is shallow well.

1500-2800 meters is a medium-deep well.

2,800-4,000 meters deep well;

Over 4000 meters are ultra-deep Wells;

2. There are many types of Wells for various purposes. The common ones are general production Wells (vertical Wells) :

The hole drilled is vertical and is called a vertical well.

Since the ideal vertical well does not exist, the field specifies standards such as drilling engineering.

If the following conditions are met, a straight well can be identified as qualified.

Directional wells and horizontal wells:

The method of drilling along the pre-designed borehole axis to reach the target layer is called directional drilling.

Drilling method, there are three basic parameters (drilling three elements) :

Bit pressure: the pressure applied to the bit.

Supplied by weight of drill string.

The amount of bit pressure is determined by the bit's bearing capacity, the weight the drill string can provide, the hole mass requirements, and the higher rate of penetration.

GREAT has designed different types of PDC bits for directional Wells.

High efficiency drilling, high ROP and more footage have been achieved.

At the same time, the PDC bit produced by GREAT can be repaired more frequently, which greatly saves the overall drilling cost.

Because GREAT very strict selection of high-quality raw materials steel and PDC cutters, and has a special processing technology, bit effect is also received by the customer's praise.

Drilling in day and night, GREAT provides 7/24 service online.
