Method of Determining Downhole Formation Grain Size Distribution Using Acoustic and NMR Logging Data |
摘要 |
The grain size distribution of a pore-scale geometric model of a clastic earth formation are adjusted so that the NMR relaxation time distribution output of the model matches a measured NMR distribution, and an acoustic velocity output of the model matches a measured acoustic velocity (compressional and/or shear). Fluid drainage and imbibing can be simulated. Additional properties of the earth formation are predicted using the pore-scale model. The additional properties may be based on additional measurements of properties of a fluid in the formation.
