摘　　要：塔东探区碳酸盐岩储层油气藏,由于溶蚀等成岩作用,形成了不同级别裂缝与溶蚀孔洞交融的多重介质储集体,为此,建立了"基岩、裂缝和溶蚀孔洞"组成的三重单渗介质物理数学模型并进行求解,得到了两个"凹子"新型的压力导数试井样版曲线,对其相应的渗流特征进行了分析。通过实例应用,进一步证明了三重介质试井模型在复杂碳酸盐岩油气藏试井评价中具有广泛的适用性。In carbonate oil and gas reservoir at Tadong exploration area,due to corrosion of Rock formation,a crack at different levels and dissolution pore blend of multiple medium reservoir has been formed,so,the physical mathematical model of triple infiltration medium composed of ' bedrock,fracture and dissolution pores' is established and to find the solution,a new type of pressure derivative well test sample curve which is formed of two ' concave' is obtained,and the corresponding seepage characteristics is analyzed. Through example application,it is further proved that the triple-porosity well test model has a wide range of reliable applicability in well testing evaluation to complex carbonate rock oil gas reservoir.
