Embodiment
[0028] The present invention relates to a kind of oil field block simulation analysis method in petroleum field, comprises the following steps:
[0029] (a) First, the basic overview of the simulated block;
[0030] (b) Then, the selection of the physical model;
[0031] (c) Next, calculate the mechanical parameters;
[0032] (d) Finally, calculation results and analysis.
[0033] The specific steps of the step (a) are: according to the established fluid-solid coupling finite element calculation model, the simulation calculation is carried out by using FEPG software.
[0034] Described step (b) comprises the following steps:
[0035] (b1) The well group is taken as the basic calculation object, and the wells outside the well group are treated as boundary conditions;
[0036] (b2) The selected block is large enough. Compared with the calculation accuracy of the well group, there is no lateral displacement on the block boundary;
[0037] (b3) Only large layers are counted, ...
