摘　　要：对比分析了水平井稳态产能计算公式陈氏公式和Joshi公式的异同。通过水平井产能影响因素:排驱面积、水平段长度、油层厚度、渗透率各项异性参数的对比计算,表明陈氏公式和Joshi公式计算的水平井产能随各种影响因素的变化趋势基本上是一致的。同时指出,由于陈氏公式中水平井椭圆排驱面积长轴半长的求解方法更合理且简便,因此陈氏公式现场实用性更强。Two methods for calculating the productivity of horizontal wells,Chen's formula and Joshi's formula,are contrasted and analyzed.By comparison and calculation of the factors affecting the productivity,such as drainage area,reservoir thickness,horizontal well length,the anisotropy ratio of reservoir permeability,it indicates that the changing trend of productivity with every influence factor from Chen's formula is accordant with Joshi's.Chen's formula is more practical due to the simple and feasible computational method of getting half of the major axis of an ellipse of drainage area in horizontal well.
