具有溶解气影响的油井不稳定IPR理论曲线的几种计算方法及对比

以不稳定渗爱理论为基础，结合Ｓｔａｎｄｉｎｇ、Ｈａｒｒｉｓｏｎ、Ｋｌｉａｓ等方法给出了无质、双孔、复合油藏等多种模型的不稳定ＩＰＲ曲线及定流压条件下的油井产量计算方法。通过３口井实际资料对比分析，认为不稳定渗透理论与Ｋｌｉａｓ方法结合计算的理论产量与实际产量吻合程度较高，适用范围广，而Ｓｔａｎｄｉｎｇ、Ｈａｒｒｉｓｏｎ方法在表皮系数较大或流压值较高的井中应用效果好。

Some Calculation Methods for Unstable IPR Theoretical Curves of the Wells with Effect of Solution Gas and Their Comparison

Based on the theory of unstable percolation flow and combined with Standing, Horrison, Klias and other methods, this paper gives out the unstable IPR curves for several models of homogeneity, double porosity, composite system, and the calculation method of well production rate under the condition of constant flow-ing pressure. The comparison and analysis of actual data from three wells indicate that the theoretical output calculated by combining the theory of unstable percolation flow with Klias method coincides, to a great extent, with actual output, its application range is wide; while Standing and Horrison methods have good application results for the wells with high skin factor and high flowing pressure.
