在二维地震勘探时，当地震测线与地层走向（或构造走向）不垂直时，时间剖面上的反射波倾角几乎都是视倾角，尤其是当穿越断层时还能同时接收到上、下盘的反射波使地震剖面出现构造假象。为此，本文针对东濮凹陷二维叠偏剖面上的“逆断假象”，利用地质模型技术剖析了逆断假象的表面现象及其形成机理，并总结出了垂向剖面法、相交测线对比法和三维空校法三种识别逆断假象的方法。利用这三种方法可准确地识别出二维叠偏剖面上的逆断假象。
In 2D seismic exploration, when the seismic line is not perpendicular to the strike (or tectonic trend) of the formation, the dip of the reflected wave on the time profile is almost always the apparent dip, especially when passing through the fault and simultaneously receiving up and down Reflected waves of the plate make the seismic section appear structural illusion. Therefore, in this paper, according to the “reverse breakage artifact” on the two-dimensional superimposed section of Dongpu depression, this paper analyzes the surface phenomena and formation mechanism of reverse breakage artifacts by using the geological model technique and summarizes the vertical section method, intersecting line measurement Contrast method and three-dimensional empty school three kinds of methods to identify the counterfeit break. Using these three methods can accurately identify the two-dimensional cross-sectional profile of the anti-breaking artifacts.
