摘要 利用物质守恒原理 ,建立地层压力线性变化趋势下考虑启动压力梯度和注水强度影响的渗流数学模型。给出了考虑注采比和启动压力梯度的平均地层压力和边界压力的确定方法。通过实例计算对比表明 ,在低渗透均质油藏的地层压力计算中 ,应该考虑注采比和启动压力梯度因素的影响 ,以提高地层压力评价的可靠性。 The mathematical model with threshold pressure gradient and injection-production ratio is constructed when the formation pressure change linearly on the base of material balance principle. The method is presented to determine formation average pressure and boundary pressure with threshold pressure gradient and injection-production ratio. The practical example is used to explain that the influence of injection-production ratio and threshold pressure gradient should be considered in order to raise the reliability of formation pressure calculation in low permeability homogeneous reservoir.
