AI Technical Summary
During wireline coring, the core may get stuck in the spring clip and be difficult to remove. Traditional hammering methods can easily damage the spring clip and the core is fragile.
A clamping assembly is used to limit and clamp the snap ring seat, and a hydraulic cylinder drives the pressing column to press the rock core, so that the rock core is evenly stressed and detached from the snap ring seat. The rock core is then stored in a storage cylinder.
This method enables rapid and complete extraction of the core sample, avoiding damage to the retaining ring and core fragmentation, and improving the convenience and stability of the operation.
