The Spearhead Base Compression Spring is a component used within the core barrel assembly to facilitate the functionality of the spearhead base or spearpoint. The spearhead base is a tool located at the bottom of the inner tube of the core barrel, responsible for capturing and holding the core sample during the drilling process.
The Spearhead Base Compression Spring serves a specific purpose within this assembly:
1. Assisting Core Sample Capture: The compression spring is positioned within the spearhead base and is designed to exert force against the core sample, ensuring that it remains securely held within the inner tube. As the spearhead base engages with the geological formation, the compression spring helps maintain constant pressure on the core sample, preventing it from dislodging during the drilling process.
2. Ensuring Sample Integrity: The spring's controlled compression plays a critical role in ensuring that the core sample remains intact and undisturbed as it is brought to the surface. By exerting consistent pressure, the compression spring helps prevent sample breakage or fragmentation, preserving the core sample's geological and structural integrity.
3. Reducing Vibrations: The compression spring also contributes to stabilizing the spearhead base during drilling operations. It helps dampen vibrations and impacts, minimizing any potential disruption to the core sample as it's retrieved from the subsurface.
4. Supporting Retrieval Efficiency: By maintaining continuous pressure on the core sample, the compression spring facilitates a smoother retrieval process. It aids in the efficient extraction of the sample from the geological formation and assists in preventing any loss of material.
PWL Core Barrel
A PWL core barrel typically comprises several key components, including an outer tube, inner tube, and a core lifter. The core lifter is a critical mechanism designed to securely hold and extract the core sample from the geological formation. The inner tube is used to collect the core sample, while the outer tube provides protection to the core sample during drilling and retrieval. PWL core barrels adhere to specific dimensions, with an inner tube diameter of approximately 3.375 inches (85.7 millimetres).
This standardized size allows PWL core barrels to be compatible with a variety of drilling equipment and systems. PWL core barrels are widely used in drilling projects related to mineral exploration, environmental studies, geotechnical investigations, and other applications that require a larger core sample for in-depth analysis.
