2D to 3D | SIS | |||
---|---|---|---|---|
Method | 2D training image acquisition mode, condition points as constraints. | Conditional data are used as constraints, and the curve fitting of variation function is used as input parameter constraints. | ||
Simulation error | All | 33.13% | All | 57.25% |
Tidal bar | 8% | Tidal bar | 11.5% | |
Sand flat | 10% | Sand flat | 12.1% | |
Error range | Tidal bar | 0%–35% | Tidal bar | 0%–42.2% |
Sand flat | 0%–43.6% | Sand flat | 0%–51.6% | |
Advantages | The reservoir architecture and morphology can be well captured from TIs so that the three-dimensional reservoir structure and morphology can be well reproduced. | Make good use of the existing geological information. Quick simulation. | ||
Disadvantages | Simulation efficiency is low because of workload. | It cannot well-reflect the reservoir morphology and configuration superimposition style. |
