对于具有边水或者底水能量的油藏,进行储量计算或动态预测时,必须考虑天然水域对油气藏开发动态的影响,准确评价油藏天然能量大小.针对定态水侵、准定态水侵、修正定态水侵和非定态水侵四种水侵类型,基于物质平衡原理,给出了实用求解方法.对于边底水油藏水侵能量计算和开发指标预测具有一定意义. For the reservoirs with edge water or bottom water energy, when calculating reserves or dynamic prediction, the influence of natural waters on the development of oil and gas reservoirs must be considered and the natural energy of reservoirs accurately evaluated. , Amending four types of water intrusion, ie, steady state water intrusion and non-state water intrusion, based on the principle of material balance, a practical solution is given, which is of great significance to the calculation of water influx energy and prediction of development index of edge water reservoir.
