Description

Technical Field

[0001] The utility model belongs to the technical field of well logging instruments, and in particular relates to a direct-push type sonic wave probe. Background Art

[0002] The acoustic system of the acoustic logging instrument is used to transmit and receive acoustic signals and is the core component of the acoustic logging instrument. The transmitting transducer inside the acoustic system transmits the signal to the formation or casing. After propagation, the signal is received by the receiving transducer of the acoustic system and then converted into an analog signal or a digital signal after processing. The signal is provided to the ground instrument for processing to interpret the characteristics of the formation (casing).

[0003] With the development of horizontal wells and high-angle wells in China, some areas need direct-push sonic logging instruments that can withstand higher temperature and pressure environments at the same time. In the existing technology, the acoustic system of sonic logging instruments is mostly used in logging environments with temperatures below 200°C and pressures below 160Mpa, and the maximum compression strength of the acoustic system is about 3 tons, which cannot meet the direct-push use requirements in higher temperature and pressure environments. In another case, most of the other domestic instruments that can meet the needs of direct-push use have an outer diameter of about 100 mm, which cannot be used in wellbores below 5 inches, and the temperature and pressure they can withstand are still only around 200°C and 160Mpa.
