Abstract

Abstract: With string of tubing elasticity energy,the self-excited technique for production is an automatic plate law-frequency vibration wakes in oil zone to clean oil flow porous, to remove plug, to improve its permeability and the fluid status, to de-
crease crude oil viscosity. The technique will decrease the water cut and increase the crude oil production. This paper analyzed the function mechanism of the technique and its design concept theoretically, and calculated the maximum pulse force as well as the maximum flushing flow and flushing velocity from the automatic vibration unit. The application of the technique by twelve wells in sites indicated that the average production increased
42% per single well and its efficiency reached 91.7%. It is an efficient new technique for the enhanced production well stimulation and enhanced oil recovery in fields during the high water-bearing interval.

Key words: self - excited production, vibration, force analysis, application
