摘要:
为了提高速度建模及成像精度,在地下断块破碎、构造复杂的HW地区首次应用了井约束速度建模技术。该技术基于井数据指导和约束速度建模,通过不断迭代,提高速度场的精度。实际成像处理过程中通过使用该技术得到了HW地区准确合理的偏移速度场,基于该速度场的逆时偏移处理取得了良好的成像效果,细节刻画更清晰,偏移深度更准确。该技术的应用一定程度提高了HW地区层位和断层的成像精度,苏北探区类似区块也有一定的借鉴意义。
Abstract:
HW project has geological characteristics of fractured block and complex structure. In order to improve the accuracy of velocity modeling and imaging, the well constrained velocity modeling was first used in the area. Based on well information guidance and constrained velocity modeling, the technology can improve the accuracy of velocity field through iteration. During the actual imaging process, the reasonable migration velocity field in HW area was obtained by adopting the technology. The reverse-time migration processing based on the velocity field obtained good effect of imaging, with more clear detail and more accurate migrated depth. The technology can improve, to a certain extent, the imaging precision of zone positions and faults in HW area. This can provide a certain reference for similar blocks in Subei Basin.
