Description
One, technical field:
The utility model relates to a kind of physical prospecting geologic examination technical field, particularly a kind of micro logging down-hole receiver of geophysical survey near surface investigation.
Two, background technology:
In the geologic prospecting that physical prospecting is carried out, the micro logging technology is one of important means of surface structure investigation, mainly be to utilize excitation well, pointwise observation at regular intervals from deep to shallow, obtain different first break times, be converted into vertically (t0) time according to the degree of depth, the match time-depth curve obtains the speed and the thickness of weathering zone.The conventional micro logging acquisition technique that physical prospecting is at present taked mainly is that different depth placement difference excites dose to excite in well, in 4 to 6 methods that common wave detector receives of face of land well head arranged around.The problem that this conventional micro logging acquisition method mainly exists: the one, the prescribe medicine degree of depth is inaccurate, usually adopts shooting pole to send the mode of detonator or explosive to the down-hole during construction, does not reach the degree of depth accurately; The 2nd, repeatedly excite difficulty.When subordinate's detonator or explosive charge, cause easily the upper level detonator short circuit, open circuit or ignite; The 3rd, efficient is too low.Conventional micro logging duration, operation inconvenience causes inefficiency.When particularly the work area required to dispose a greater number micro logging, efficiency was especially obvious.
Three, utility model content:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of low cost, portable band is provided, easily obtains data, micro logging down-hole receiver that the degree of reliability is high.
Its technical scheme is: mainly be made of interface section, data transmission cable, sealing sensing box, sensor, rechargeable type high-pressure gasbag and balancing weight, the two ends of described data transmission cable are connecting interface part and balancing weight respectively, the center section of described data transmission cable connects a plurality of sealing sensing boxes, assembly sensor in sealing sensing box, each sensor passes through to connect the rechargeable type high-pressure gasbag as propulsion plant by parallel connecting interface part in a side of described data transmission cable.
Above-mentioned data transmission cable adopts hyperchannel pair twist data transmission cable, adopts the DGZ-24 connector to cooperate with the interface section, finishes the connection of the transmission of multi channel signals.
Above-mentioned sealing sensing box is streamlined sealing injection moulding.
Above-mentioned rechargeable type high-pressure gasbag adopts the polyurethane air bag, as the coupling propulsion plant of the well seismometer and the borehole wall.
The beneficial effects of the utility model are: solved the inaccurate problems such as repeatedly exciting difficulty and heaviness that reach of the conventional micro logging prescribe medicine degree of depth, effectively improved operating efficiency, have positive effect to improving exploration effects, filled up domestic blank, realized the effective tool of physical prospecting near surface investigation.
Four, description of drawings:
Accompanying drawing 1 is a principle assumption diagram of the present utility model;
Accompanying drawing 2 is structural representations of sealing sensing box of the present utility model;
Among the last figure: interface section 1, data transmission cable 2, sealing sensing box 3, sensor 4, rechargeable type high-pressure gasbag 5 and balancing weight 6.
Five, embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
The utility model mainly is made of interface section 1, data transmission cable 2, sealing sensing box 3, sensor 4, rechargeable type high-pressure gasbag 5 and balancing weight 6, the two ends of described data transmission cable 2 are connecting interface part 1 and balancing weight 6 respectively, the center section of described data transmission cable 2 connects a plurality of sealing sensing boxes 3, assembly sensor 4 in sealing sensing box 3, each sensor 4 passes through to connect rechargeable type high-pressure gasbag 5 as propulsion plant by the parallel day part 1 that connects in a side of described data transmission cable 2.
The DGZ-24 connector is adopted in above-mentioned interface section 1, finishes the connection of the transmission of multi channel signals, and data transmission cable 2 adopts hyperchannel pair twist data transmission cable, and sealing sensing box 3 is streamlined sealing injection moulding.
During use, according to recording geometry, select the sensor 4 of some, single-sensor 4 is installed in the sealing sensing box 3, after waterproof, pressure-resistant treatments, be connected in the 55 core data transmission cables 2, the rechargeable type high-pressure gasbag 5 that adopts 13MPa is as well seismometer coupling propulsion plant, select balancing weight according to the well depth parameter, reach the accuracy of gathering the physical points position.Wherein, rechargeable type high-pressure gasbag 5 adopts the polyurethane air bag, by the polyurethane air bag each sensor 4 is carried out best coupling backup, by ground excitation apparatus and register instrument, the physical points signal transmission that sensor is received also records seismic instrument, and preserve and data processing, finally obtain geologic section.
