摘　　要：以达西定律为基础 ,建立了一个基于含水率与注入孔隙体积倍数的实用水驱规律模型 ,应用该模型可以预测水驱产油量或采收率。将预测结果与采用其他提高采收率措施时的产油量或采收率进行对比 ,可以分析实施该措施的增产效果。利用水驱规律模型对某区块进行了实例分析 ,结果表明 ,注入 0 .1倍孔隙体积的胶态分散凝胶(CDG) ,可以使全试验区增产油量 969t,其中有近 1 /Based on Darcy's law and relation between water cut and pore volume, a practical equation for describing water flooding regulation was established. The oil production and recovery efficiency was predicted, and the efficiency of enhanced oil recovery (EOR) obtained from the equation was analyzed and compared with the oil production and recovery efficiency by applying the (EOR) technology. The practical application shows that oil production was raised by 969 t after 0.1 V p colloid dispersed gel (CDG) was injected in the pilot area. One third of raised production was accomplished in the central well.
