In the initial stage of production of a gas reservoir with abnormally high pressure, the forces of action of gas expansion, reservoir rock compaction and elastic expansion of compressed grains and connate water as well as water influx from the compaction of surrounding shale add to compensate for the energy loss and reduce the rate of formation pressure decline. So, the plot of shut-in bottomhole pressure (P/Z) versus cummulative production (G_p) shows two distinct segments: the initial segment with a gentle...

In the initial stage of production of a gas reservoir with abnormally high pressure, the forces of action of gas expansion, reservoir rock compaction and elastic expansion of compressed grains and connate water as well as water influx from the compaction of surrounding shale add to compensate for the energy loss and reduce the rate of formation pressure decline. So, the plot of shut-in bottomhole pressure (P/Z) versus cummulative production (G_p) shows two distinct segments: the initial segment with a gentle slope representing the pressure decline for the initial stage of production, followed by a steeper one for the normal pressure system, or the hydrostatic pressure system (see Figs. 1-2). Prediction of gas reserve in place based on the initial segment would certainly lead to errors; but we can not predict the gas reserve in place based on the steeper portion of the plot, for, in that case, we would have to wait till the establishment of a normal pressure system usually after the recovery of 20-25% of gas in place. Based on the princiole of energy conservation and with the application and derivation of the material balance equation, the author of the paper has proposed a method of predicting gas reserves in abnormally pressured gas reservoirs which has been proved quite dependable.

It is the basis of estimating reserves and making up development plan of the gas reservoir to determine gas reservoir drive type.The methods of apparent formation pressure and water invaded volume factor,which are often used at present in China,have a less sensitivity to water drive effect,thus causing misjudgement on drive type frequently,so that how to utilize the early production performance data to accurately judge the drive type in gas reservoir is always a difficulty for reservoir engineers.A new method—apparent geological reserve method which may identify the drive type in gas reservoir at the early stage of gas reservoir development under the condition of low recovery percent is proposed in the paper,being suitable not only for the gas reservoirs with normal pressure system but also for those with overpressure system.It is proved by a great number of examples that this method is quite sensitive to the water drive effect in gas reservoir and the judgement accuracy of the method is much higher than that of the traditional one.

气藏驱动类型的确定是气藏储量计算和开发方案编制的基础。我国目前常用的方法———视地层压力法和水侵体积系数法对水驱作用的敏感性较差,往往造成对驱动类型的误判,故利用早期生产动态资料准确判断气藏驱动类型一直是油藏工程师的一个难题。文章提出了一种可用于气藏开发初期,在较小采出程度条件下,识别气藏驱动类型的新方法———视地质储量法,它不仅适用于正常的压力系统气藏,而且还适用于异常高压系统气藏。通过大量的应用实例证明:该方法对气藏的水驱作用十分敏感,其判别准确率明显高于传统的方法。
