随钻测压取样工具FASTrak HD在渤海油田的应用

电缆地层测试在定向井作业中受井眼轨迹和井况等影响，实施难度大、风险高，对储层评价带来较大影响。FASTrak HD仪器作业不受井眼轨迹限制，作业风险低，它不仅保留Testrak全部功能，而且增加流体分析模块、压降泵和样桶模块，具备了取样功能，解决了定向井测压取样难的问题。在渤海油田的首次应用取得成功，为后续定向井的测压取样作业提供了新的作业方式，具有一定的指导意义。

Application of FASTrak HD Pressure Test and Sampling While Drilling in Bohai Oilfield

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.
