THE EFFECTS OF OPERATING PARAMETERS IN THE PERFORMANCE OF INTERMITTENT GAS-LIFT.
ABSTRACT. THIS ARTICLE PRESENTS A STUDY OF THE BEHAVIOR OF THE INTERMITTENT GAS-LIFT CYCLES AND OF THE RELATIONSHIPS AMONG THE VARIABLES OF THE SYSTEM. A SIMULATOR WAS DEVELOPED FOR THE FOUR INTERMITTENT METHODS: CONVENTIONAL, WITH PLUNGER, WITH CHAMBER AND WITH PIG. THE CASE OF A TYPICAL WELL IS PRESENTED FOR VARIOUS RESERVOIR CONDITIONS - RESERVOIR S STATIC PRESSURE HEAD AND PRODUCTIVITY INDEX. THE PRESENT RESULTS INCLUDE THE EFFECTS OF THE INJECTED VOLUME OF GAS, THE GAS-LIFT VALVE, THE SLUG CHARGE AND THE VALVE PRESSURE RATIO IN THE VOLUME OF LIQUID PRODUCED AT THE SURFACE, THE CYCLE PERIOD AND THE DAILY AVERAGE FLOW RATE, FOR ALL FOUR METHODS. THIS WORK WILL HELP THE ENGINEER TO UNDERSTAND THE BEHAVIOR OF THE PROCESS, TO DESIGN AN OPTIMIZED SYSTEM AND TO SELECT THE BEST ONE.
KEY-WORDS: INTERMITTENT GAS-LIFT, ARTIFICIAL LIFT, PETROLEUM PRODUCTION.
