本文建立了描述异常高压气藏地层压力和动态储气空间的数学模型——动态模型。对异常高压气藏的压降特征进行理论分析后认为,在不带水域的情况下,压降曲线(P/Z与G_p)呈拟抛物线,认为是两个直线段的看法仅仅是对该曲线的近似处理。本文还从我国气田的实际情况出发,提出了在缺乏气藏参数的情况下的储量计算方法,通过实例检验,证明方法是可靠的。
In this paper, a mathematical model describing the formation pressure and dynamic gas storage space in anomalously high pressure gas reservoirs has been established. After analyzing the pressure drop characteristics of abnormally high pressure gas reservoirs, it is considered that the pressure drop curves (P / Z and G_p) are pseudo-parabola in the absence of water area, and it is considered that the two straight-line segments are only for the curve Approximate processing. Based on the actual situation of gas field in our country, this paper puts forward the calculation method of reserves in the absence of gas reservoir parameters, and proves that the method is reliable by examples.
