弹性驱动下油层能量转换与补偿泵的增产过程分析

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

应用弹性液体不稳定渗流理论的研究成果与油层能量转换的数学模式，对普通泵采油和补偿泵采油的压降漏斗最大半径的变化进行了分析及对比计算，结果表明：在补偿泵与普通泵采出相同总液量的条件下，前者的压降漏斗的最大半径显著地小于普通泵采油时的压降漏斗最大半径，即补偿泵采油时，有更长的稳产期，能达到增加产出总液量的目的。

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.
