摘要
稠油油田蒸汽驱采油在我国刚刚开始。基于热平衡的原理,本文提供了一个解决蒸汽前缘及其推进速度的一维两相概算法。在 N·D·舒特勒等人一维分析的基础上,用求极值的办法确定了含汽率曲线上汽前缘饱和度处的切线方程,并归纳了一套包括饱和压力下的蒸汽温度、粘度、热焓以及汽化潜热等热参数的经验统计公式。实现了全部计算过程的程序化,并以一个蒸汽驱并组的实例进行了示范计算。
Steam drive in heavy oilfield development is on its beginning in our cou- ntry.This paper gives a one-dimensional,two-phase approximate calculation model for the estimation of the steam front and the advance speed of steam based on the heat balance principle.Based on the one-dimension analyses by N.D.Shutler etc,the equation of tangent at a point giving steam saturation at the position of the steam front on the curve of steam ratio has been esti- blished by means of the method of extremes.A complete set of empirical for- mular,including temperature,viscosity,heat content of the steam,latent heat of vaparization and other parameters has been derived.Computer proce- ssing has been realized for all above calculations.The paper gives a sample calculation also.
