Abstract: In this paper,the problem is studied about the well test of analyzing a multi-layered commingled reservoir with unequal initial layer pressure,unequal physical parameter,unequal geometric parameter,and none flow between the layers.In the case of commingled production,the well bore storage and skin effect are considered.The computing method of typical curve of well test model and the matching method of the parameters of each layer are given as well.The defined condition of well test model is that each layer is homogeneous reservoir,inner boundary is penetrated straight well,outer boundary may be infinity,semi-infinity,angle reservoir, closed reservoir. Transient pressure analysis is performed through the calculation of some normal boundary condition.

Key words: multi-layered commingled reservoir, analysis of well test, method, layered-flow rate, initial wellbore pressure
