摘　　要：苏里格气田进行水平井开发将成为一种趋势，苏里格气田水平井储量起算标准的计算尚无明确方法。在前人研究的基础上，以盈亏平衡原理为依据，借鉴定向井储量起算标准的建立过程，确定了水平井储量起算标准计算的盈亏平衡公式。使用Arps递减分析法，给出了指数递减、双曲递减、调和递减3种递减规律下水平井的储量起算标准的计算方法。最后，以苏里格气田苏47井区为实例，说明了水平井储量起算标准计算的具体过程和方法。Development with horizontal wells will become a tendency in Sulige Gasfield. However, there is no definite method for a standard to calculate the threshold reserves in horizontal wells of this gas field. Based on the predecessors＇ studies and break-even theory, referring to the establishment process of threshold reserves standard for directional wells, the break-even formula of the threshold reserves standard for horizontal wells was established. By utilizing the Arps decline analysis method, the calculation methods of the threshold reserves standard for horizontal wells were proposed under the three types of decline laws： exponentiaI decline, hyperbolic decline and harmonic decline. Finally, by taking the well Su47 area in Sulige Gasfield as an example, the specific process and methods of obtaining the calculation of threshold reserves standard for horizontal wells were illustrated.
