【摘要】：井中地震的接收或激发设备位于井中,接近目的层或目标地质体,避免了近地表和环境干扰,得到的地震波信息能更直接反映地层、油藏或目标体的地质属性,其精度和探测范围介于地面地震和测井方法之间,成为两种技术的空间(纵向、横向)拓展和有效补充;井中地震深度、时间、速度、时变子波、频谱及相对能量关系等信息相对精确,具有识别精度高、数据保真度高的特点。随着油气勘探开发目标日趋复杂和多种井中地震技术快速发展且日益成熟,井中地震将在复杂构造、复杂储层、复杂油气藏的勘探开发中发挥关键作用,特别是Walkaway/Walkaround/三维VSP、微地震等技术,在复杂构造地震成像、提高分辨率地震处理、储层连通性识别、剩余油预测、油气藏建模等方面,将会发挥独特和不可取代的重要作用。
[Abstract]:The equipment for receiving or triggering earthquakes in wells is located in the well, which is close to the target layer or the target geological body, avoiding the near surface and environment interference, and the obtained seismic wave information can more directly reflect the geological attributes of formation, reservoir or target body. Its precision and detection range are between ground seismic and logging methods, and become the space (longitudinal, horizontal) expansion and effective supplement of the two technologies. Seismic depth, time, velocity, time-varying wavelet, frequency spectrum and relative energy relationship are relatively accurate and have high recognition accuracy. With the increasingly complex targets of oil and gas exploration and development and the rapid development and maturity of various seismic techniques in wells, in-well earthquakes will be in complex structures and reservoirs. The exploration and development of complex reservoirs play a key role, especially Walkawayr / Walkaround3D VSP, micro-seismic imaging in complex structures. Improving resolution seismic processing, reservoir connectivity identification, residual oil prediction, reservoir modeling and other aspects will play a unique and irreplaceable important role.
