Title:
GUIDED LOCKING RAM BLOCKS
Document Type and Number:
WIPO Patent Application WO/2017/223237
Kind Code:
A3
Abstract:
A ram block assembly enables a very high shearing, breaking, or parting force by utilizing guide rails and passageways within the ram block assembly to accept the rails and gird the rails against deviation from intended trajectory. The ram block rails and cavities enable application of extreme forces, opposing and concentrated within a small area, when actuating the ram block assemblies into the "open" or "close" positions. The ram block assemblies move in opposition, approaching each other and applying opposing forces against any material positioned between the ram block assemblies, and deforming, severing, breaking, shearing, parting, tearing and/or cutting, as the case may be, any said material positioned between the ram block assemblies. The severing of materials in the wellbore is known as "shearing," and the apparatus performing this shearing operation as shear rams, shear ram blocks, shear blocks or shears.
