ANALYSIS ON CONVERSION OF FORMATION ENERGY AND PRODUCTION INCREASE PROCESS OF COMPENSATORY PUMP IN ELASTIC DRIVE

The variations of maximum radius of pressure drop funnel were analysed and calculated in oil production with compensatory pump and conventional pump, using transient flow of elastic liquid through porous media and mathematical models of formation energy conversion. It is showed that the maximum radius of pressure drop funnel of compensatory pump is obviously smaller than that of conventional pump in same gross liquid production, i.e., the longer stable production period will be obtained and the gross liquid production will be increased in production with compensatory pump.
