Method and apparatus for measuring the abrasion rate of sized bridging materials used in drill -in fluid formulation |
| abstract |
Methods and apparatuses are provided for testing and quantifying structural durability characteristics such as the abrasion rate of bridging materials used in drilling fluids. Embodiments include sieving to create uniform batches having particles within a predefined range. Embodiments include selecting and drying a batch, separating the dried batch into dry samples, and selecting a test sample. Embodiments include sealing the test sample, a volume of liquid, and a rod in a cylindrical testing cell and rotating the cylindrical testing cell containing the rod such that the rod rolls in relation to an inner wall of the cylindrical testing cell and applies force partially crushing the test sample. The testing cell is built as a sealed wet rod milling device. Embodiments include sieving a resulting sample to create a durable sample having particles within the predefined range and drying the durable sample. Embodiments include measuring a mass of the dried durable sample to define a durable mass and comparing the durable mass to the initial mass of the test sample. |
