Design of dual-source through casing acoustic logging tool and application examples
Through-casing logging technology has important development prospects in mature fields. A dual-source through-casing acoustic logging tool is designed. The operation principle and the overall design of the tool are carried out, especially the spacing distance between the transmitting transducers. A dual-source transmitting circuit is designed to send out two excitation signals of opposite polarities, and the shape selection of the excitation waves is researched. This tool was logged in casing wells with different cementation qualities in Shengli oilfield, and the logging results showed that the instrument could obtain high-quality formation signals in casing wells with different cementation qualities, which was consistent with the measurement results of open-hole wells.
