TEST TECHNIQUE AND APPARATUS FOR PERFORMING FLOW TESTS SIMULATING A GRAVEL FILTER A LABORATORY ENVIRONMENT AT DOWNHOLE CONDITIONS

摘要

The present invention relates to a gravel filter assembly. The gravel filter assembly, in one case, includes a housing having first and second opposing surfaces, the first and second opposing surfaces defining a thickness that simulates a desired downhole gravel filter thickness. In this case, the test gravel filter assembly includes an opening extending entirely through the housing from the first surface to the second surface, the opening having a diameter which simulates a desired perforation diameter of the well casing. downhole drilling and a retaining screen coupled near the first opposite surface and over the opening.
