By Using Optical Fiber Cable Transmission Several Frequencies Of Acoustic Logging Technology Research

Currently, the sonic logging has become an indispensable modern logging methods, withelectrical and other logging methods irreplaceable role. The traditional acoustic instrumentsto detect the radial depth of wells is small, the resolution is poor, the sound wave out theinformation collected is not comprehensive, is difficult to accurately assess the formation ofinformation, this paper several frequency array acoustic logging technology to explore andstudy, a large improvement in the level of the sonic depth and resolution of the radial probe,resulting in more accurate, such as porosity, rock and other geological information, the betterfor oil exploration and development area to provide a basis. However, with the loggingtechnology, new equipment gradually produce sound logging methods, the new digitalequipment toward the signal, transmitting and receiving probe array in the direction ofdevelopment, and therefore the amount of log data has also increased rapidly, which givescable logging a higher data rate requirements.Based on the above technical information, this paper decided to use fiber optic cabletransmission frequency of the acoustic logging of several technical studies, on the one handby changing the traditional wireline transmission cable used, the use of higher data rates, agreater amount of fiber-optic cable transmission As a transmission medium, on the other handthe use of several multi-frequency acoustic emission and probe combination will mine thefrequency of collection of acoustic signals transmitted quickly to the ground, after inversionto explain the underground formation to obtain information.Finally, well after the simulation experiments and testing of the system, verify that thesystem reached breaking wireline high-speed data transmission technology bottlenecks tosolve the multi-frequency array acoustic logging process large amount of information,technical issues such as signal distortion, while the rich get underground strata sonic log information to better division of lithology. For the wireline industry has opened up newdirections of data transmission. Through the signal transmission, the transmission carrierfrequency array and a variety of acoustic logging tool with applied research, promote thedevelopment of acoustic logging technology.
