background technology:
Dipole shear wave logging technology originally mainly utilizes an one pole sound source and a doublet source to carry out compressional wave, shear wave detection, to obtain the various geologic parameters in wellhole.Because the tranmitting frequency of one pole, doublet source limits, stratum can not be goed deep into far.Dipole shear wave Detection Techniques far away are extensions of dipole acoustic log technical development in recent years, utilize the low frequency flexural wave that four component doublet sources excite below frequency at it, there is enough penetration depths, and the SH reflection wave received has certain amplitude, can be received by highly sensitive four component receiving transducers and differentiate.
utility model content:
The purpose of this utility model is the geological structure requirement of analyzing and researching in order to adapt to well week tens of meters of scopes in modern petroleum, mineral exploration development process, and the dipole sonic of a kind of double frequency of specialized designs, tunable source distance far detects emission sound source device.
Its technical scheme is:
A kind of double frequency, the dipole sonic of tunable source distance far detects emission sound source device, comprise height, the doublet source of low two kinds of frequencies, wherein: high-frequency doublet source and low-frequency doublet source are sleeved on the two ends of hollow connecting rod, hollow connecting rod between high-frequency doublet source and low-frequency doublet source is set with spring and baffle ring, one of high-frequency doublet source or low-frequency doublet source are relative with hollow connecting rod to be fixedly connected with, slide with hollow connecting rod after baffle ring is connected with another low-frequency doublet source or high-frequency doublet source and coordinate, hollow connecting rod there is several locating hole vertically uniformly at intervals, baffle ring is provided with locating slot, locating slot and locating hole are by alignment pin lock fit.
Such scheme is further defined to:
Described low-frequency doublet source is fixedly connected with hollow connecting rod, and slide after high-frequency doublet source and baffle ring are connected and be sleeved on the hollow connecting rod other end, spring is located between low-frequency doublet source and baffle ring.
