Product Description
- Product Overview
The PDC Hole Reamer (Polycrystalline Diamond Compact Reamer) is a high-efficiency tool for oil and gas drilling, horizontal directional drilling (HDD), and borehole enlargement. Key functions include:
- Enlarging wellbore diameters in soft to medium-hard formations to optimize wellbore stability4.
- Minimizing surface disruption in trenchless drilling applications, particularly in complex geological conditions5.
- Utilizing PDC cutters for enhanced wear resistance, cutting efficiency, and tool longevity
2. Structural Design
Critical design features include:
- Materials & Manufacturing:
- Main body forged from AISI 4145H alloy steel for high strength and fatigue resistance4.
- Spiral blades or wings to reduce torque fluctuations and improve stability during reaming
-
- Functional Components:
- Tapered/straight-body design for centralized alignment and symmetrical hole enlargement
- Replaceable nozzles to maintain cutter cleanliness and prevent cuttings accumulation
- Multi-wing configurations for efficient rock fragmentation in hard formations
3. Application Scenarios
- Formation Adaptability:
- Soft formations (clay, loose shale): Spiral blades facilitate rapid cuttings removal, minimizing balling risks47.
- Medium-hard formations (dense shale, limestone): PDC cutters combined with high-pressure jets ensure effective rock breaking47.
- Operational Modes:
- Inline connection with drill bits for simultaneous drilling and reaming4.
Configurable for pull reaming (post-drilling) or push reaming (during drilling

5. Operational Guidelines
- Matching Requirements:
- Select blade count and cutter density based on hole size, formation hardness, and drilling fluid properties
- Prioritize high-pressure jet nozzles in sticky formations to prevent cutter fouling
- Maintenance:
- Regularly inspect PDC cutters for wear to avoid reaming deviations
- Clean internal flow channels post-operation to prevent clogging
