Screen Pipe for Thick Oil Thermal Recovery in Horizontal Well Completion

摘要

A screen pipe, comprises a base pipe with a plurality of oil inlet holes arranged on an outer wall of the base pipe; wherein the screen pipe comprises: a plurality of reinforcing ribs are disposed on an outer circumference wall of the base pipe along an axial direction of the base pipe; a wrap wire is winded at intervals on the plurality of reinforcing ribs along a circumferential direction of the base pipe; and a triangular block shaped foam iron is filled in a space between two adjacent reinforcing ribs of the plurality of reinforcing ribs. When the present invention is in use, the thick oil enters into the gap between the wrap wire and the drive pipe through the wrap wire gap. After filtration by the foam iron, the thick oil enters into the base pipe through the inlet hole, realizing pumping and transportation of the oil.
