METHOD AND DEVICE FOR SIMULTANEOUS SEPARATE EXPLOITATION OF SEAMS Russian patent published in 1994 - IPC

FIELD: oil industry. SUBSTANCE: method is based upon testing production of seams for paraffin presence. Production of pure seam (paraffin free) is directed completely onto walls of perforated part of seam production string through centrifugal guiding mechanism which has paraffin, and the seams are mixed. After than mixture is advanced onto top surface. Device has well pumps suspended on string of depth-pump rods in string of pump-compressor tubes. The latters are mounted inside production string equipped with packers. Device has connecting pipe-line which communicates with annular cavity formed between branch pipes. The branch pipes and blades form centrifugal guiding mechanism. Branch pipes have hubs in their lower part under the lowest packer. EFFECT: improved exploitation capability; improved efficiency. 2 cl, 4 dwg
