从Zoeporritz方程理论出发,讨论了反射P—P波和转换P—S波的反射系数,进而将二者结合起来,将P—S波反射系数与P—P波反射系数的比值定义为控制因子Q,作为设计联合勘探观测系统的一个重要影响参数。在同一个介质条件下,应该使Q值尽量的大,这样才能使得P—P波与P—S波的接收处于可比、可用的状态,因此,在同一个观测系统中可以同时接收到这两种波,大大提高了生产效率。通过理论模型的计算,设计了几个同时接收P—P波和P—S波的观测系统,验证了控制因子Q的合理性与重要性。
Based on the theory of Zoeporritz equation, the reflection coefficients of reflected P-P wave and converted P-S wave are discussed, and then the two are combined to define the ratio of reflection coefficient of P-S wave and P-P wave as control factor Q, as an important influence parameter in the design of joint exploration and observation system. Under the same medium conditions, the value of Q should be made as large as possible so that the P-P wave and the P-S wave are received in a comparable and usable state. Therefore, both of them can be simultaneously received in the same observation system Seed waves, greatly improving production efficiency. Through the calculation of the theoretical model, several observation systems that receive P-P wave and P-S wave simultaneously are designed. The rationality and importance of the control factor Q are verified.
