摘要
本文在考虑了地层束缚水压缩率作为压力的函数而变化的基础上,为异常高压气藏建立了一个更为严谨的数学模型.求解并得到了新的压降方程和储量计算方法。实例计算表明,此方法与现有方法相比,可使储量计算精度提高10％左右。
Based on considering the variety of the compressibility of formation connate water as a function of pressure, a more precise mathematical model is set up for the gas reservoir with abnormally high for- mation pressure and through solving, a new pressure drop equation and a new reserve calculation method are obtained. It is indicated through calculating an example that this mothod compared with the available method,the precision of reserve calculation can be raised about 10%.
