| 摘 要： | 与常规的小型测试压裂不同，流体注入诊断测试（DFIT）是通过关井阶段出现的拟线性流或拟径向流阶段求取储层压力，采用改进的梅耶霍夫方法（M-method）解释储层渗透率。以长庆榆林气田一口开发井为例，依据DFIT的技术原理和测试步骤，对该井测试压降数据进行解释分析，结果可信度较高，证明了该项工艺在长庆低压低渗油气田的可行性。

| Abstract: | Different from conventional small type fracture,DFIT is to acquire reservoir pressure by appearing imitate linearity flow or imitate ra- dial flow phase at well close period and interpret formation permeability by modified M method. By a sample of a developed well in Changqing Yulin gas field, according to technical principle and testing procedure of DFIT, interpreting and analyzing pressure drop- ping data, the reliability of the result is much high and the feasibility of this tech applied in low pressure and percolation of Changqing gas field is proved. |
