摘要
对于无夹层的底水油藏，建立典型底水油藏水平井开发数值概念模型，计算了多种情况下的水脊形态，拟合了水脊剖面公式。利用多元非线性回归方法确定了水脊影响因素与系数a1、a2、a3的关系，建立了水脊定量描述公式，推导了水脊高度和水脊体积计算公式。以Z油藏一口水平井为例，验证了定量描述公式，结果表明定量描述公式计算结果满足矿场需要。
The numerical conceptual model of typical bottom-water oil reservoir with no interbed is established and the water cresting shapes in several conditions are calculated. And moreover the formula of water cresting cross sections is matched. By means of multivariate nonlinear regression method j the relations between water cresting influencing factors and coefficients a1 , a2 , a3 are determined, the quantitative characterizing formula of the water cresting is set up, and furthermore the formulas of the water cresting heights and volume are deducted. The validity of quantitative characterizing formula is confirmed by taking suits show that the quantitative characterizing formula can Z Oil-reservoir＇s horizontal well as an example. The re- meet the requirements of the field.
