Abstract: Wireline formation test is difficult to implement and has high risk because it is easily affected by well trajectory and well conditions in directional well operation. As result, it has a great impact on reservoir evaluation. The FASTrak HD of Baker Hughes company is not limited by well trajectory and has low operation risk. It not only retains all functions of Testrak, but also adds fluid analysis module, pressure drop pump and sample barrel module. Moreover it is capable of sampling so that the problem of pressure measurement and sampling of directional wells is solved. This tool has been successfully applied for the first time in Bohai Oilfield and provides a new operation mode for pressure measurement and sampling of subsequent directional wells.
