Simulation of Counter-Current Imbibition in SRVs of Tight Oil Reservoir

Zhongyi Xu, Linsong Cheng, Renyi Cao, and Sidong Fang
Abstract—During the process of tight oil exploration, counter current imbibition effect is significantly different due to the presence of complex fracture network and flow characteristics in tight oil reservoir. To simulate counter-current imbibition in fractured tight oil reservoir properly. PEBI grids are used to match the complex fracture network, natural fractures and matrix are idealized as dual-porosity medium, rate of mass transfer of imbibition between matrix and fractures is treated as source or sink term in dual porosity model. A new semi analytical model for the calculation of mass transfer function of counter-current imbibition in the presence of complex fracture network is presented by using radial integration boundary element method (RIBEM), In addition, to reflect the flow characteristics of tight oil, relative permeability and capillary pressure curve, which have considered the effect of boundary layer, has also used in the mass transfer model. Besides, with a field example from tight oil reservoir, we show the capacity and practical use of the model. From simulated results, it is concluded that counter-current imbibition place an important role on the early and middle stage of exploration and the existence of boundary layer makes the contribution of imbibition to oil production greatly reduced.

Index Terms—Tight oil reservoir, boundary layer, counter current imbibition, RIBEM.
