Full-waveform In Cracked Formations

As technology advances, the total human demand for resources has become more increase. Production of human society in all areas of life in need of resources, mainly by use of its various combustion minerals, such as: coal, oil, gas, and so on. Among them, the oil is worthy of the energy required for today's world's first material, and because of its non-renewable nature, it is only through the exploitation of the exploration and utilization for a variety of exploration methods to detect underground oil deposits. Therefore, for oil exploration methods used in the various science and technology will also become important to find the extraordinary.In this article I described a methods which is a petroleum exploration tool in an application, it should be said that an analysis. Reservoir through the cracks for various traits (direction, angle, orientation, width, length, etc.) detection analysis, and then observed fluctuations in fractured reservoirs through which the law of propagation conditions and various properties of waves (range, speed, etc.) the change, and to find both possess this certain, stable, close contact and relationships. Through these particular relationships, we can determine the fracture is located in the character of reservoir geological properties. Then that these cracks surrounding geological characteristics of mineral deposits, ore reserve to determine the ability of the ability of oil and gas reserves, oil and gas flow capacity, and the existence of which oil and gas. Reached here for the reservoir content, product form, value, etc. to determine the purpose of exploitation, such an analysis to determine the reservoir has very important significance.However, because the specific actual circumstances surrounding different, in several different categories, and the fracture of the characters are also diverse, coupled with the volatility of the launch is not qualitative change, in which the wave train in general contain very many the various types of fluctuations. Therefore, the analysis of these situations requires a lot of data collection, and careful theoretical analysis. This is to face this article topic. General full wave can be seen as the superposition of various waves, the full wave with longitudinal wave, shear wave, Stoneley wave, pseudo-Rayleigh wave, and so on. Each wave of which has different properties, Such as their amplitude, speed, attenuation effects are different characteristics, so we can see through the launch of their different characters for its own time change the fracture characteristics of the state also have their own, while These characteristic traits but also with the crack, fissure where the reservoir, the geological characteristics of rock is closely related to, or even can be said to reflect the qualitative relationship. Thus, by the full wave characteristics in the different fracture propagation in rock media to determine where the fractured geological features and reservoir characteristic is both a complex and valuable analysis of important issues.This article explain the cracks for different traits for the full waveform of each stack of Singapore law, the selection of a representative of several typical cases to analyze the fracture characteristics of the changes in volatility. Also, set the background of this article has some specificities that is set in the Hudson model theoretical analysis of the context, of course, with a lot of real data, some empirical formula is derived, and theoretical basis of the formula Combined analysis. Therefore we can say, though the article is not complete, comprehensive analysis of the fractured reservoir cover all media out of the full wave propagation, but can already reveal that the Hudson model set of representative case of the theoretical background Conclusions. Therefore, after the full wave propagation in fractured reservoir in the reservoir affects judgments of a certain reference value.
