利用丙型水驱曲线计算油田储量的方法

Calculation of oil reserves by means of C-type water-flooding curve

利用动态资料计算地质储量丰富了计算已开发油田地质储量的方法,指出该方法计算地质储量的实质是利用可采储量和采收率的商来计算,并给出该方法的不足和改进方向.同时给出由相对渗透率曲线拟合所得因数含义是最大采收率,探讨把该因数作为最大采收率的可行性.给出计算剩余可采储量的直接方法,实际应用表明,丙型水驱曲线计算结果更符合实际,且方法简单实用.

The method of calculating OOIP(original oil in place) the developed oil field by means of the dynamic data enriched the methodology for the calculation of the geological reserves in the developed area.The method was that the recovery ratio was divided by recoverable reserve and the shortage and modified aspect were discussed.The meanings of the coefficient obtained by regressing relative permeability curve was ultimate recoverable ratio and was deeply probed into.The new method for calculating the remaining recoverable reserve was brought forward.The result of practical application indicated that it was simple and the method was practical.
