摘　　要：针对低渗透性储层的特点，充分考虑实测压力的流动期和恢复期数据，建立了新的数学、物理模型，得出了DST全压力拟合方法的典型曲线并对其进行分析。通过实例分析可知：DST全压力拟合法计算结果比较符合地层实际情况。对于未出现径向流的DST测试资料，该方法也能提供较为满意的地层参数，具有较强的实际应用价值。In accordance with the characteristics of low permeability reservoir,and fully considering actual pressure data from flowing and build up periods, this paper creates a new mathematical and physical model, generates and analyzes type curve of DST all pressure match approach. Through analysis of actual examples,it indicates that the calculation results of DST all pressure match approach are rather con formable to actual formation conditions. For DST test data without appearance of radial flow, this approach is also able to provide satis factory formation parameters,so it has great value of practical application.
