Considering the effect of gas slippage, this paper presents a mathematical model of gas flow through low-permeability gas reservoir and finds pseudopressure and pseudotime functions which make the mathematical model and de finite solution condition linearized When the new pseudopressure and pseudotime are used, the model of gas flow through lowpermeabilitygas reservoir becomes the same form as the conventional mathematical model of reservoir permeability. Therefore, when the pseudopressure and pseudotime functions defined in this paper are used, the mature theory of well test analysis may be useed to explain the well test data of low-permeabi lity gas reservoir. The method of calculating corresponding pseudopressure and pseudotime values from well test data in low-permeability gas reservoir is discussed in the paper. The effect of gas slippage on calculating pseudobressure and pseudotime values is also discussed. It is shown from field examples that the results obtained are satisfactory and the new method is proved to be an effective one for analyzing well test data in low-permeability gas reservoir.

本文在考虑低渗透气藏气体渗流的滑脱效应下,建立了低渗透气藏气体渗流数学模型。找到了一种可以使该数学模型及其定解条件线性化的拟压力函数和拟时间函数。使用这种新的拟压力函数和拟时间函数时,低渗透气藏的渗流数学模型变成具有常规油藏渗流数学模型一样的形式,因此,当采用本文定义的拟压力函数和拟时间函数时,可以借助于成熟的油井试井理论来解释低渗透气藏气井试井数据。文中还探讨了由低渗透气藏气井试井数据计算相应的拟压力函数位和拟时间函数值的方法,探讨了滑脱系数对计算拟压力函数值拟时间函数值的影响等。通过矿场实例分析表明,本文方法效果较好,这为解释低渗透气井试井数据找到了一种行之有效的方法。

According to the theory of unstable well testing and the analysis of a large quantity of data obtained in field, the authors hold that in well testing, the gas production of a low permeability gas well should match with the gas supplying capacity of the gas reservoir; otherwise, it is impossible to obtain the correct and reliable result of well testing interpretation. If the gas production is greater the gas supplying capacity, the straight line segment of "false radial seepage flow" will appear in pressure semilog curve. The gas supplying capacity and permeability of the gas reservoir obtained from the false pressure semilog curve will have great error.

From analysis of the production performance and percolating characteristics of low permeability gas reservoir, the characteristics of elastic 2 phase method curves and pressure drawdown curves of low permeability gas reservoir were studied. If the production from wells drilled in low permeability gas reservoir is over high, it will cause insufficient gas supply, present "pseudo steady state", and create the dynamic reserve calculated by elastic 2 phase method being on the low side. Besides, low permeability reservoir follows the natural percolation law of fluid flowing through "easily permeable zone first, difficultly permeable zone last" and "high permeable zone first, low permeable zone last". In addition, the build up time needed by artificial shut in well is short and the present formation pressure measured is on the low side (unsteady), resulting in the pressure drawdown curve presenting "multi section type". Thus, if the dynamic reserves are calculated generally by pressure drawdown method-only by "a pressure drawdown curve", the error will undoubtedly be big. Based on this, the authors put forward applicable conditions and new methods that can be used for accurately applying elastic 2 phase method and pressure drawdown method to the determination of dynamic reserves of low permeability gas reservoir. This plays an important part in understanding the characteristics of dynamic reserves of low permeability gas reservoir and getting reliable calculation result.

根据低渗透气藏生产动态及渗流特征 ,分析应用弹性二相法、压降法确定其动态储量的适用条件。低渗透气井产量过大使气藏供气能力不足时 ,出现的“假拟稳态”会造成用弹性二相法计算的动态储量偏低。天然气先沿容易渗流的物性好的气层流动 ,且低渗透气藏关井恢复测压时间有限 ,得到的当前地层压力值偏低 (未稳定 ) ,导致压降 储量曲线呈“多段型” ,若将不同开发阶段的数据笼统回归为 1条压降 储量直线 ,计算的动态储量必然误差较大。提出了正确应用弹性二相法、压降法确定低渗透气藏动态储量的方法。
