In conventional wireline and LWD/MWD formation testing, downhole predictions for rock fluid properties are based on simplified Darcy flow models, but only mathematical expediency. These require initially constant pressures that uniform throughout the reservoir. This limitation precludes common applications in overbalanced drilling, so supercharge or near-well invasion effects - associated with ...

At present, there are only a few existing models that can be used to predict the relative permeability of unsaturated soil under deformations, and calculation process is relatively complex. In order fit measured value coefficient before deformation, this work employs simplified unified model soil, it obtains index λ deformation soil. addition, remains unchanged after deformation. Based on actua...
