Abstract
The invention belongs to the geophysical exploration field, and relates to a deep well piezoelectric detector. The detector comprises an annular piezoelectric ceramic plate and a leading-out conductor thereof, a soft sheath, a close cover which is fixed at the two ends of the sheath, a hole arranged on the close cover; and the leading-out conductor runs from the hole. The deep well piezoelectric detector is characterized in that the annular piezoelectric ceramic plate is enwrapped by a nylon net. The deep well piezoelectric detector has the advantages of simple wiring, strong interference resistance and reliable transmission.
Description
Technical field
The invention belongs to the geophysical survey field, relate to a kind of detector arrangement that is used for deep-well petroleum prospecting process.
Background technology
At present, the wave detector that the seismic acquisition signal is used is varied, but can not solve the signals collecting work of deep-well well.Compare with conventional piezoelectric seismometer, the environment for use of deep well piezoelectric detector is abominable, service condition is poor, owing to there is not the suitable wave detector that can be used for the high pressure waterproof, general in the past employing solid piezoelectric wave detector solves, and the sensitivity of solid piezoelectric wave detector is low, waterproof effect difference and be difficult to problems such as maintenance.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, a kind of good pressure-resistant performance is provided, can insert 3000 meters down-hole, realize the deep well piezoelectric detector of signals collecting.
The object of the present invention is achieved like this:
A kind of deep well piezoelectric detector comprises the ring piezoelectric potsherd and draws lead, soft sheath, be fixed on the capping at sheath two ends, in capping, offer porosely, draw lead and from the hole, pass, described ring piezoelectric potsherd is wrapped up by nylon wire, and takes out taut band by nylon and be fixed to described lead.
As preferred deep well piezoelectric detector according to claim 1, the material of described sheath is a polyurethane; In sheath, be marked with light wax oil; Described capping is a steel.
The material of the oversheath of piezoelectric seismometer of the present invention is a polyurethane, promptly withstand voltage, corrosion-resistant, be again soft material, polyamine fat oversheath has the performance of entrant sound, acoustic pressure can see through polyamine fat oversheath makes the ring piezoelectric potsherd produce deformation, and the ring piezoelectric potsherd produces electric signal; Utilize nylon wire and take out tight rope the ring piezoelectric potsherd is fixed to draws on the lead, fixed form is simple, can satisfy fixedly requirement; Inject light wax oil in the space between polyamine fat oversheath and ring piezoelectric potsherd, light wax oil has the effect of the annular piezoelectric ceramic piece of protection, prevents that the ring piezoelectric potsherd is crushed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing: referring to Fig. 1, most important part of the present invention is a ring piezoelectric potsherd 7, the inboard of one end of ring piezoelectric potsherd 7 and the outside are drawn lead 2 and lead 1 respectively, be used for the output of electric signal, the other end is drawn lead 10 and lead 11, is used for the fixing of ring piezoelectric potsherd 7.Ring piezoelectric potsherd 7 is taken out taut band 6 by nylon wire 5 parcels by nylon and is fixed on lead 1, lead 2, lead 10 and the lead 11.Above-mentioned these are packed in the polyamine fat oversheath 9, are sealed by steel loop 4 and capping 3, inject light wax oil 8 then.
Claims (4)
1. deep well piezoelectric detector, comprise the ring piezoelectric potsherd and draw lead, soft sheath, be fixed on the capping at sheath two ends, in capping, offer porosely, draw lead and from the hole, pass, it is characterized in that, described ring piezoelectric potsherd is wrapped up by nylon wire, and takes out taut band by nylon and be fixed to described lead.
