To analyze the pseudo phenomena caused by migration velocity error, the paper firstly studied the depth error between post-stack migration and prestack migration caused by same velocity error, and found the depth error was only relative to velocity error and had no direct matter with methods of depth migration (post-stack migration or prestack migration). Then the paper did numerical simulation of a complex lenticular body model with wave-equation modeling and migration, and found that the velocity error could not only induce depth error, but also could change the modality of construction and the event of subjacent layers. Furthermore, it could change the frequency of reflective event. They are the pseudo phenomena caused by migration.

从分析偏移速度误差带来的各种假象出发，本文首先对比分析了速度误差对叠后深度偏移和叠前深度偏移的影响，发现偏移剖面的深度误差仅与速度模型的误差有关系，与具体的偏移方法没有直接的关系；然后对一个复杂的透镜体模型进行了波动方程叠后正演和偏移计算，详细地讨论了不同的速度误差带来的各种假象，发现速度误差不仅会带来深度误差，而且会造成构造体的形态变化，下覆地层同向轴的扭曲，还可能引起地层同向轴的频率发生变化，给资料解释带来一定的假象。

The earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree,which precede flowers and fruit —— not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic.

Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. Form the principle of GR logging, calculate volumes in investigating areas taken by borehole, formation, up and low shoulder beds, along with distance between center of gravity of the four unit bodies and detector. Based on the above, the weighting function of each unit body to GR signal contributions are established, thus realizing processing of GR logs with high resolution. The resistivity logging model uses "resolution matching" method to improve the resolution of the logs. After the process, PNN model is made to recognize the oil-gas-water bed. Compared with BPNN, the net work is featured swiftness, accuracy and ease of practical application.

When in the sedimentary formation these living thing chemical energy material, arrives between the earth's crust and the mantle rock magma region, because receives the high temperature high pressure the function, can the instantaneous aggravating internal heat response degree, also because these biological energy material stratum distributes non-uniform, thus has further created the partial region superheat, then intensified the profile conduction and the instantaneous paroxysm, finally intensified earth's surface and so on the earthquake volcano as well as plate movement terrain changes.

当沉积地层内的这些生物化学能物质，到达地壳与地幔之间的岩浆区域，由于受到高温高压的作用，就会瞬间加剧内热反应的程度，又由于这些生物能物质的地层分布不均匀，从而进一步造成了局部区域的过热，进而加剧了波形传导和瞬间爆发性，最终加剧了地震火山以及板块运动等地球表面的地形变化。
