Table 6 Permeability within sealing zones of fault rocks derived from calculated cross-fault pressure differences in two fault groups.
From: Evaluation of lateral sealing capability of fault-controlled gas storage at different periods
Type | Depth of weak points /m | Is it closed | Maximum differential pressure /MPa | Correlation with time |
|---|---|---|---|---|
Actual injection and production data of gas storage facility | −1249 ~ − 1254 | Closed | 2.47 ~ 2.82 | Relational |
Characterization of fault sealing capability based on primitive gas reservoir anatomy | −1249 ~ − 1254 | Closed | 0.263 ~ 0.312 | Unrelated |
Characterization of fault sealing capability based on dynamic development data | −1249 ~ − 1254 | Closed | 2.5 ~ 2.78 | Relational |
