摘　　要：结合苏里格气田的实际，建立了适合该气田产能评价的”单点法”数学模型，研究了苏里格气田”单点法”试井测试的基本条件。结果表明，“单点法”产能试井方法是苏里格气田产能分析的一种十分有效的方法，但该方法在具体使用过程中．必须遵守一定的测试条件。苏里格气田气井应至少生产200h，用“单点法”计算的无阻流量才能可靠地反映地层实际情况。According to practical situation of sulige gas field, the empirical formula which is adjust to the low permeability and low pressure gas field was established through the study of academic basis of traditional “one point” deliverability equation. Meanwhile, the testing condition of “one point” deliverability testing was analyzed and verified. The results presented that the “one point” deliverability testing is an effective method for the productivity analysis of sulige. However, some special testing conditions must be satisfied during the use of the method. While gas well had produced for more 200h at least and the ratio of down hole pressure is under 80%, the truth of stratum can be reflected by the open-flow capacity which is obtained from the “one point” deliverability testing.
