The conditions to measure accurately and the principles to select parameters of the multi— probes EST method are proposed, and the theoretical research, computer imitation and the experiment on a machine tool prove that these principles and suggestion are necessary and effective. The influence of the initial value errors of the probes, the installation error of the probes system, and the remaining error caused by the radical error motion are analyzed quantitively on the measurement accuracy of the multi—probes EST method. The influence of the error caused by the probe's axes which is not in a plane and the perpendicularity error of the plane which the probe's axes is in to the stational axis are discussed on the measurement results.

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。

This thesis deals with oil-water flow rate measurement using a venturi and develops a differential pressure-based two-phase flow rate measurement model, which does a terrific job with the use of a water fraction device.
