摘要
推出凝析油 -气两相渗流方程 ,引入凝析油 -气两相拟压力 -时间函数 ,使渗流方程线性化 .针对低渗凝析气藏的钻杆测试问题 ,在研究凝析油 -气的段塞流动特征的基础上 ,建立了描述凝析气段塞流动的初 -边值问题 ,求出这一问题解 ,并把褶积理论引入凝析气段塞流动资料分析模型中 ,建立了短时段塞流动资料解释的新理论与新方法 。
This paper has inferred the filtering equation of a condens at e oil-gas two phases, and introduced pseudo-pressure function of a condensate oil-gas phases and given the filtering equation linearized. The question of dri ll-stem test for low permeable condensate gas reservoir bass on slug flow featu re of condensate oil-gas has built the question of elementary-boundary value, and sought the solution, furthermore drawn the feature curves for it's pressure -solution. These curves' important applications are given in reservoir gas. The convolution theory is introduced into model of data analysis for slug flow of c ondensate gas.
