摘　　要：为了解决动态法计算分类井动用地质储量存在的储量互相动用的问题,研究了喇萨杏油田相对渗透率曲线和地质储量对水驱特征曲线的影响,通过水驱特征曲线斜率和由相对渗透率曲线得到的信息,得出反求地质储量的动态方法。该方法既考虑了油田动态,还考虑了油田的油层渗流特性,是利用动态资料推算动用地质储量方法的发展。同时,从油藏工程原理出发,应用全区指标对动态法计算的分类井地质储量进行了校正,更为准确地确定了分类井控制地质储量,为分类井开发分析和指标预测奠定了基础。In this paper, the effect of relative permeability curve and geologic curve on waterflooding characteristics in Lasaxing oilfields is studied. Based on the slope of wateflooding characteristics and information from the relative permeability curve, the reversed dynamic method to calculate geologic reserves can be obtained. For this method, not only dynamic state but also the filtering flow features of Lasaxing oil reservoirs are taken into account, the dynamic data is applied to calculate the geologic reserves. In this paper, the mutually reserves concerned when calculation the geologic reserves of different types wells with this method is analyzed. Based on reservoir engineering fundamentals, the geologic reserves of different types calculated with dynamic method are corrected with the application of the indexes of the total area. So, the geologic reserves controlled by different typed wells are determined more accurately to provide information for development analysis and index prediction of different types wells.
