发明名称 SAND CONTROL SCREEN ASSEMBLY HAVING AN INTERNAL SEAL ELEMENT AND TREATMENT METHOD USING THE SAME
摘要 <p>A sand control screen assembly (90) that is positionable within a wellbore comprises a base pipe (92) having a blank pipe section (94) and a perforated section (96) having at least one opening (98) that allows fluid flow therethrough. A filter medium (100) is positioned about the exterior of the base pipe (92) that selectively allows fluid flow therethrough and prevents particulate of a predetermined size from flowing therethrough. An internal seal element (104) is positioned at least partially within the perforated section (96) of the base pipe (92). The internal seal element (104) controls the flow of fluid through the opening (98) of the base pipe (92) such that fluid flow is prevented from the interior to the exterior of the sand control screen assembly (90) but is allowed from the exterior to the interior of the sand control screen assembly (90).</p>
