摘要：

异常高压气藏高温高压条件下，气-液界面相理论验证了在气藏气相中始终饱含有大量水蒸气。若在计算异常高压有水气藏地质储量过程中忽略水侵和气相水蒸气的存在，将产生较大误差。在广义异常高压气藏物质平衡原理的基础上，考虑气藏外部水体水侵及气藏气相中水蒸气含量，推导了异常高压有水气藏物质平衡方程，并给出了计算气藏地质储量的方法。实例证明，利用仅考虑气藏外部水侵方法或仅考虑气相水蒸气含量方法和容积法计算的异常高压有水气藏地质储量均偏大，其误差分别为2.38%、2.93%、3.62%。考虑气藏外部水侵及气相中水蒸气含量的异常高压有水气藏物质平衡方程能够较准确地计算气藏地质储量。

Abstract:

It has been verified by the theory of gas-liquid interphase that the gas phase under the conditions of high temperature and high pressure in abnormal-pressure gas reservoirs always contains a great deal of vapor. If the presence of this vapor in gas phase or the external water influx is neglected during the calculation of the original gas in place(OGIP) for abnormal-pressure gas reservoirs with aquifer, larger errors in the calculation would be inevitable. Based on the generalized material balance principle for abnormal-pressure gas reservoirs, the present paper deduced a modified material balance equation that takes both the external water influx and the vapor content in gas phase of abnormal-pressure gas reservoirs with aquifer into consideration, then an approach to calculate the OGIP was obtained. A case study showed that the OGIP was too larger if calculated by using any of the following three methods, namely the one considering only the external water influx or the vapor content in gas phase, or the volumetric method. The relative errors by using these methods were 2.38%, 2.93% and 3.62%, respectively. Therefore, the modified material balance equation for abnormal-pressure gas reservoirs with aquifer proposed in this paper could calculate the OGIP more accurately due to its consideration not only of the external water influx but also of the vapor content in gas phase.

Key words: abnormal-pressure gas reservoir with aquifer, material balance equation, gas-liquid interphase, water influx, vapor, original gas in place(OGIP)
