摘要
从递减率定义出发,建立了水驱油藏产油量递减率与综合含水率、采油速度、含水上升率、产液量变化率4个影响因素之间的变化关系式,提出一种产油量递减率影响因素分解方法。通过该方法可以量化每个影响因素对产油量递减率的贡献大小,明确产油量递减率的主要影响因素,为油田下步调整挖潜、减缓递减的措施提供依据。应用表明,该方法能够满足油田实际产液量变化要求,且具有简单、方便、可操作性强的特点,易于矿场的推广应用。
Based on the decline rate definition,the relationship between oil production decline rate and comprehensive water cut,oil recovery rate,water cut rise rate and change rate of liquid yield was established,and a decomposition method of influencing factors of oil production decline rate was proposed.Through this method,the contribution of each factor to oil production decline rate can be quantified,and the main influencing factors of oil production decline rate can be defined,which can provide a basis for the next adjustment and measures to slow down the decline.The example shows that the method can meet the demand of the actual liquid yield and has the characteristics of simplicity,convenience and maneuverability,and and it is easy to be popularized and applied in the field.
