Summary Introduction
This document is an expanded abstract.

Increasing demand for oil and gas resources in a cost-efficient way has significantly accelerated the development of MFHWs which have considerably enlarged the reservoir exposure and efficiently connected comparatively low-permeability flow regions in reservoirs with well-developed natural fractures. Hydraulic fractures are generally created to connect with existing natural fractures for larger productivity. Due to the complex communication of hydraulic fractures to natural fractures, flow behaviors through the porous reservoir and from the reservoir to the horizontal wellbore have become much more complicate (Gu l., 2017). To cope with such situation, as illustrated in the

, Brown et al. (2009) first put forward a practical Trilinear Dual-Porosity Flow Model for MFHWs and took into account the effect of the outer reservoir flow region and the influence of natural fractures in the inner reservoir flow region on transient pressure behaviors by using the dual-porosity model (Warren and Root, 1963).
