Product highlights:
1. Downward Impact Specialist
Generates powerful downward jarring force through mechanical energy conversion – ideal when conventional drilling jars fail.
2. Dual-Energy Storage System
Combines potential energy (drill stem lift) + spring strain energy for amplified impact force.
3. Multi-Functional Integration
Enhances cutting efficiency with mechanical internal cutters and synchronizes with reversing units for thread compensation.
4. Adjustable Impact Dynamics
Jarring force scales with key factors: hanging weight, spring extension length, and stroke length.
5. Rugged Mechanical Simplicity
All-metal construction ensures reliability in high-shock oil tools applications.
Overview of Fishing Bumper Sub
The KXJ Type Fishing Bumper Sub is an essential mechanical fishing tool designed to free severely stuck drilling tools in wells where conventional upward jarring proves ineffective. As a specialized drilling jar variant, it operates by converting stored mechanical energy into high-intensity downward impacts. When lifting the drill stem, the tool accumulates potential energy through controlled spring extension. Subsequent sudden lowering releases this energy, accelerating the drill stem downward until the Bumper Sub reaches its closed position – generating a targeted downward impact on stuck objects ("fish"). Compatible with mechanical internal cutters and reversing units, it also provides critical feeding force during cutting operations and compensates for rising strokes during thread reversal in oilfield and drilling operations.
Advantages of Fishing Bumper Sub
✅ Force Amplification Control
Impact strength scales with operational parameters:
- ↑ Hanging weight = ↑ Force
- ↑ Spring extension = ↑ Force
- ↑ Stroke length = ↑ Force
✅ Reduced Fishing Time
Enables repeated jarring cycles without tripping, cutting recovery time by ≤50% versus traditional methods.
✅ Enhanced Tool Synergy
Boosts efficiency of cutters/reversing units – a critical force multiplier for **oil tools** assemblies.
✅ Fail-Safe Mechanical Design
No hydraulics or electronics ensures operation in high-temp/high-shock environments where conventional oil tools fail.
✅ Minimal Training Required
Simple operation and adjustable mechanics reduce deployment complexity for drilling crews.
