摘 要
Pulse source is a new kind of high-power, high bandwidth, controllable and repeatable strong sound source. The sound source has a broad application prospect in the fields of national defense, industry, medical treatment and so on. In this paper, the microscope is introduced into the fracture detection of oil well, the working principle of paraboloid reflector is collected, and the effects of frequency and well diameter on the energy accumulation characteristics of the microscope are studied. Two main frequencies, 3kHz and 7kHz, are obtained after the energy accumulation of microscope, which can be used for deep detection and borehole fracture detection respectively. In the detection of borehole fracture, the influence of vertical fracture far away from borehole wall on the whole wave and reflected P wave of microscope is studied. At the same time, the influence of the horizontal fracture intersecting the borehole on the microscopic Stoneley wave is analyzed. The results show that after energy accumulation, the microscope can effectively enhance the energy information of the whole wave and the reflected wave, and provide help for the subsequent inversion of formation fractures.
