Abstract
The utility model discloses a multi-core water-proof detector series which is a seismic wave receiver used for petroleum and seismic exploration and is suitable for difficult areas, such as a marsh, a beach, an intertidal zone, etc. The utility model is composed of a plurality of multi-core detectors. A plurality of installing grooves for installing electromechanical transducers are arranged in each of the multi-core detectors, and a single multi-core detector is formed. The utility model has the advantages of simple structure, convenient operation, strong interference resistance, accurate data, low labor intensity, raw material saving and strong applicability.
Description
The utility model relates to a kind of oil seismic exploration instrument, and particularly a kind of seismic event receiving trap is suitable for the reception of regional seismic events such as marsh, seabeach, mesolittoral zone.
Existing string mainly adopts a plurality of single core wave detectors to form certain series and parallel and connects mode.When open-air seismic prospecting adopts the mode of weighting to receive seismic event, need several single core wave detectors to be embedded in together, more loaded down with trivial details, inefficiency during retractable cable, and joint is many, easily produce electric leakage, short circuit, open circuit, external interference, fall phenomenons such as tail cone, especially be not suitable for the field construction of the areas in hardship such as marsh, seabeach, mesolittoral zone.
The purpose of this utility model provides a kind of multicore string, solves problems such as regional electric leakage such as marsh, seabeach, mesolittoral zone and inefficiency.
Task of the present utility model is done in such a manner:
With a plurality of electromechanical transducers more than two, by the seismic prospecting designing requirement, form different series and parallels and connect mode, then each electromechanical transducer is positioned over and has in tail cone and the metal shell by tankage, draw by fairlead with lead-in wire, with sealing substance the electromechanical transducer in the shell is fixed, and sealed circuit between them.The fairlead place tightens the back sealing with rubber blanket and screw with holes, with the top cover that has O-ring seal, is fixed in the top of shell, makes its inside be in the secondary seal state.Constitute a multicore wave detector like this, interconnect between wave detector and the wave detector, constitute multicore water proofing geophone string, using method is the same with common string, has solved problems such as regional electric leakage such as marsh, seabeach, mesolittoral zone and inefficiency.
The utility model is compared with existing string, and it is strong, simple in structure to have applicability--and tail cone and shell one are not prone to the tail cone phenomenon.If easy to use, anti-interference strong--use aluminium shell, can shield external electric field.Data are accurate, save starting material, reduced labour intensity.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a cut-open view of the present utility model.
Fig. 2 is the vertical view of shell 2.
Fig. 3 is the left view of multicore water proofing geophone.
Referring to Fig. 1, Fig. 2 and Fig. 3, a top cover (1) that has O-ring seal (5) is screwed on the shell (2) that has tail cone and mounting groove (6).Screw with holes (3) makes its sealing draw the fairlead of line (7) rubber pad (4) extruding, constitutes a multicore string, gets final product work.
Claims (4)
1, a kind of multicore string is characterized in that hermetically sealed electromechanical transducer, is loaded in the shell (2) that has tail cone, with the top cover (1) that has O-ring seal (5) and screw with holes (3) and rubber blanket (4), to the electromechanical transducer secondary seal.
2, multicore string according to claim 1, the shell (2) that it is characterized in that having tail cone is provided with several mounting grooves (6) and fairlead (7).
3, multicore string according to claim 1 is characterized in that having the top cover (1) of O-ring seal (5), is screwed on the shell (2).
4, multicore string according to claim 1 is characterized in that rubber blanket (4) prevents locating in screw with holes (3), and fairlead (7) is sealed.
