摘要
复杂逆掩构造逐渐成为塔里木盆地油气勘探的重点领域。完善变速成图技术,提高构造成图精度是准确落实这类圈闭的关键。在充分研究目标工区的难点的基础上,本文提出了一套适应浅层速度建模、复杂逆掩区建模、模型层析速度建场、井震联合速度建场等变速成图新技术。在塔里木盆地库车山地的综合应用结果表明,这些新技术取得了良好的效果。
Complex overthrust structure has gradually become the important field of oil/gas exploration in Tarim basin.Completing variable-velocity mapping technique and improving the structural mapping precision are the keys clarifying such kind of traps.On the basis of fully studying the difficulties of objective area,the paper presented a set of new variable-velocity mapping technique suitable for shallow velocity model-building,model-building in complex overthrust area,tomographic velocity field building of model ...
