钻进和修井时,了解复杂圈闭的几何形态以及受断层影响的液流形式很关键。在Teak油田,由于大部分油区的地震分辨率很差,使该油田的作业尤为复杂。三维地质解释和可视化技术使对未排泄叠加层段的识别、评价、目标确定及成功的钻探成为可能。在设计油井轨迹时,用全三维模型可成功地避开压力递减层段,或做适当的准备。 When drilling and working on a well, understanding the geometry of the complex trap and the form of liquid flow affected by the fault is critical. In the Teak field, the operation of the field is particularly complicated due to the poor seismic resolution of most of the oil zones. Three-dimensional geological interpretation and visualization techniques make it possible to identify, evaluate, target and successfully drill un-drained overlay intervals. When designing the well trajectory, the full 3D model can be successfully used to avoid pressure drop zones or to prepare properly.
