简介：3D可视化技术是与传统的地震数据解释技术完全不同的一种新地震解释技术。这个方法作为一个单位拿地质的身体或兴趣的任何3D区域并且集成使3D成为视觉解释的身体的点，线，和飞机。这种技术能与连贯技术是综合的解释复杂差错。空间领域自动地平线跟踪能精确地决定结构的特征。目标雕刻能用倒置数据决定空间尺寸和观点3D岩性学身体的深度程度。我在Qinan的西方的斜坡在Dagang油矿和微妙的水库的预言的Guanxi区域把这种技术用于复杂的块结构的解释与好结果下垂。这研究显示视觉解释技术能广泛地并且有效地在油地开发并且到被使用改进探索成功比率。

简介：当前，大多数MT(magnetotelluric)数据仍然在稀少的调查线上被收集并且因为域工作费用，解释了使用2D倒置方法，工作区域环境等等。然而，有从总是导致错误地地质的解释的3Dgeoelectrical结构的MT数据的一些2D解释限制。在这份报纸，我们使用了3D倒置方法解释MT稀少的线数据。在模型测试，稀少的行数据是从一个测试模型产生并且处理了使用3D的MT完整的信息数据结合坡度倒置代码。倒置结果证明这个倒置方法合理、有效。同时，我们证明为有不同元素参数的倒置结果，由阻抗张肌数据和tipper数据的联合倒置的结果对测试模型更精确、更靠近。
