摘要
本文根据三种驱动(气体的膨胀、外来水的侵入、岩石和束缚水的膨胀)作用在各类气藏开发过程中都存在的客观实际,提出了用变容物质平衡这一概念来描述这种非定容气藏的物质平衡问题,从而把现有的几种物质平衡方程用一种极为简单的形式统一起来。经方法验证和实用证明,在理论和实践上都是可行的。
According to the objective reality that three driving mechanisms(gas expansion,encroachment of allochthonous water,expansion of rock and connate water)all exist in developing process of various gas reservoirs, this paper presents that the concept of variable volume material balance is utilized to de- scribe the problem of material balance of these gas reserviors without constant volume. Thereby,sever- al present material balance equations are united with an extremely simple form. It is feasibble in theory and practice through method verification and demonstration in applicaion.
