摘要
根据岩心资料和测井资料 ,运用统计学计算方法、Dykstra H方法和劳伦兹曲线法 ,分别计算了渗透率变异系数。结果表明 ,商三区古近系沙二下亚段储层层间非均质性不明显 ,而层内非均质性严重。因此 ,沙二下油藏采用一套层系开发是合理的 ,采用脉冲式周期注水开发比较好。
Based on core and well logging data, permeability variation coefficients are calculated respectively by using the methods of statistical calculation, Dykstra H and Lorentz curves. The results show that the interbedded heterogeneity is not obvious in the lower members of Es_2 of Eogene system in Shangsan Region, where intrastratal heterogeneity is severe, thus the development for reservoirs in the lower members of Es_2 is reasonable and pulse type development of cyclic water injection is used with better result.
