Application of flow potential analysis technique based on numerical simulation in the development of fractured-vuggy reservoir

Youqicang pingjia yu kaifa, 2020
The energy of fluid in oil reservoir determines the direction of fluid flow. In order to study the energy distribution of fluid in fractured-vuggy reservoirs, a theoretical model of fluid potential is established, and the 3D fluid potential ...

Research on unit mining by elastic drive of fractured-vuggy carbonate reservoir with bottom water by water intrusion

Youqicang pingjia yu kaifa, 2020
As Tahe fractured-vuggy carbonate reservoir has many fractured-vuggy units, pressure systems and seepage units, its oil-water relation is complex and the water body energy distribution is unbalanced.

Displacement efficiency in the water flooding process in fracture–vuggy reservoirs

Journal of Petroleum Exploration and Production Technology, 2017
To determine how fracture–vuggy structure, pressure, and injection–production mode influence displacement efficiency in the water flooding process in fracture–vuggy reservoirs, two types of models were built based on the characteristic of such reservoir: two fracture models with different fracture apertures and two fracture–vuggy models with different ...

Generalized multiscale multicontinuum model for fractured vuggy carbonate reservoirs [PDF]

Journal of Computational and Applied Mathematics, 2020
Simulating flow in a highly heterogeneous reservoir with multiscale characteristics could be considerably demanding. To tackle this problem, we propose a numerical scheme coupling the Generalized Multiscale Finite Element Method (GMsFEM) with a triple-continuum model aimed at a faster simulator framework that can explicitly represent the interactions ...
