摘要: The well screen has an outer tube and a telescoping inner tube. The tubes have identical horizontal series of slots therein. The outer tube is initially adjusted longitudinally with respect to the outer tube to gauge the slot openings through the communicating slots of the tubes. Solvent cement is used for securing the tubes in adjusted position.
