The application discloses a kind of reservoir acidification
simulation methods for oil reservoir scale, it is related to oil and gas
field development technical field.The acid rock reaction flow
system of reservoir is decoupled into three-dimensional matrix continuous domain and one-dimensional discrete
wormhole topology net, constructs pressure and flow
coupling equation, acid liquid transport and reaction equation and geometric shape evolution equation to carry out reservoir acidification
simulation, the pressure field of three-dimensional matrix continuous domain and one-dimensional discrete
wormhole topology net is fully implicit simultaneous solution, obtains the
fluid pressure distribution in reservoir, determines the volume flow and flow direction in one-dimensional discrete
wormhole topology net, constructs
directed acyclic graph, executes
topological sorting and generates downstream calculation sequence calculation to obtain the acid liquid concentration field in one-dimensional discrete wormhole topology net, in combination with geometric shape evolution equation, the geometric parameter of one-dimensional discrete wormhole topology net is updated explicitly, generates new tip node and new wormhole
pipe section using geometric topology update, until tip node breaks through production boundary, obtain the
simulation result of reservoir acidification.
