Inclined wells has recently been adopted to develop fractured-vuggy carbonate hydrocarbon reservoirs (FVCHRs) composed by matrix, fracture and vug system. Therefore, it is significant for us to describe pressure transient of inclined well for FVCHRs. In this paper, it is assumed that vug and fracture system connect with wellbore, and inter-porosity flow from vug to fracture system appears. Therefore, the pressure transient responses model of inclined well with triple-porosity dual-permeability behavior was built. The model is solved by employing Laplace integral transform and finite cosine Fourier transform. Real-domain solution of the model is obtained by Stehfest inversion algorithm. On the basis model of the published paper, the solution of the simplified model of this paper was validated with horizontal and vertical well of FVCHRs with triple-porosity dual-permeability behavior, and results reach a good agreement. Type curve, according to pressure derivative curve characteristic, can be divided into eight flow regimes, which includes wellbore storage, skin reflect, early vertical radial flow, top and bottom boundary reflection, linear flow, inter-porosity flow from vug to fracture, inter-porosity from matrix to vug and fracture and pseudo-radial flow regimes. The influence of some vital parameters (inclination angle, inter-porosity flow coefficient, well length and permeability ratio etc.) on dimensionless pressure and its derivative curves are discussed in detail. The presented model can be used to understand pressure transient response characteristic of inclined wells in FVCHRs with dual-permeability behavior.

最近已经采用斜井来开发由基质，裂缝和孔洞系统组成的缝洞型碳酸盐烃储层（FVCHRs）。因此，对于FVCHRs描述斜井的压力瞬变对我们而言意义重大。在本文中，假设孔洞和裂缝系统与井眼相连，并且出现了从孔洞到裂缝系统的孔隙间流动。因此，建立了具有三孔双渗透特性的斜井压力瞬态响应模型。通过使用拉普拉斯积分变换和有限余弦傅里叶变换来求解该模型。通过Stehfest反演算法获得模型的实域解。根据已发表论文的模型，通过三孔双渗透行为的FVCHRs水平井和垂直井对本文简化模型的求解进行了验证，取得了良好的一致性。根据压力导数曲线的特性，类型曲线可分为八种流态，包括井筒存储，表皮反射，早期垂直径向流，上下边界反射，线性流，从孔洞到裂缝的孔隙间流-从基质到孔洞的孔隙度和断裂以及伪径向流态。详细讨论了一些关键参数（倾角，孔隙间流动系数，井长和渗透率等）对无因次压力的影响及其导数曲线。
