Abstract
The utility model discloses a signal transmitting device of an electromagnetic wave resistivity logging instrument, which overcomes a defect that the present lifting device needs to keep an enough distance with an electromagnetic wave resistivity instrument to avoid interfering the electromagnetic wave resistivity instrument. The signal transmitting device includes a seven-core cable (1), an elastic force type cable roller (2), a trolley (4) and a seven-core load-bearing cable (9) for logging, wherein the seven-core cable (1) is arranged along a tower arm (3) of a tower crane and connected with the seven-core load-bearing cable (9) for logging by bypassing the elastic force type cable roller (2); and the elastic force type cable roller (2) is arranged on the trolley (4) capable of reciprocating along the tower arm (3). The embodiment of the utility model can be used on the tower crane to lift the electromagnetic wave resistivity logging instrument, thereby effectively ensuring the instrument lift and the data transmission when logging.
Description
Technical field
The utility model relates to a kind of transmitting device, relates in particular to a kind of signal transmitting apparatus of electromagnetic wave resistivity logging instrument.
Background technology
When logger is tested, need erecting equipment to mention instrument and go into the well, need simultaneously cable to carry out the data synchronous transfer.Because the metal framework of erecting equipment has interference to the electromagnetic wave resistivity logging instrument, like this electromagnetic wave resistivity instrument just need with erecting equipment (except directly over to be used for the hawser of transfer of data and lifting) maintenance distance more than 10 meters, this has proposed higher requirement to execution conditions, and construction cost is high.
The utility model content
Technical problem to be solved in the utility model is to overcome present erecting equipment need to keep enough distances just can avoid interference the defective of electromagnetic wave resistivity instrument with electromagnetic wave resistivity instrument.
In order to solve the problems of the technologies described above, the utility model provides a kind of signal transmitting apparatus of electromagnetic wave resistivity logging instrument, comprise seven core cable (1), elastic type cable drum (2), dolly (4) and well logging with seven core bearing cables (9), wherein:
Seven core cable (1) arranges along the tower arm (3) of pillar crane, walks around elastic type cable drum (2) and links to each other with seven core bearing cables (9) with well logging; Elastic type cable drum (2) is arranged on can be along on the reciprocating dolly of tower arm (3) (4).
Preferably, the top of the tower arm (3) of pillar crane is arranged with cable support bar (5) in parallel, is provided with a plurality of cable links (6) on the cable support bar (5); Seven core cable (1) passes these cable links (6).
Preferably, this device comprises: be fixedly mounted on the halter (10) on the suspension hook (7) of pillar crane.
Preferably, halter (10) is fixedly mounted on the suspension hook (7) of pillar crane by suspender belt (8) and fastening devices.
Preferably, logger string (11) is connected with seven core bearing cables (9) with well logging by halter (10).
Compared with prior art, embodiment of the present utility model can be used for the electromagnetic wave resistivity logging instrument that hoists on the pillar crane, and instrument hoists and transfer of data in the time of can effectively guaranteeing to log well.
Description of drawings
Fig. 1 is organigram and the application scenarios schematic diagram of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing embodiment of the present utility model is elaborated.Need to prove that in the situation of not conflicting, the embodiment among the application and the feature among the embodiment be any combination mutually.
Consider that going the span of hanging so will be enough large if outdoor use row is lifted up into row to hoist, so just need enough large place, construction costs also can be very high simultaneously.Embodiment of the present utility model selects pillar crane to substitute row and hangs.The tradition pillar crane only has jack up unit and can not the equipment of slinging be powered and communication, so can't be used for the test of logger.
As shown in Figure 1, the transmitting device that hoists of the utility model embodiment comprises that mainly seven core cable 1, elastic type cable drum 2, dolly 4, suspender belt 8 and well logging are with seven core bearing cables 9 etc.
Cable support bar 5 is arranged on the top of the tower arm 3 of pillar crane abreast, and a plurality of cable links 6 are arranged on the cable support bar 5.Seven core cable 1 passes these cable link 6, one ends and connects ground system, and the other end is walked around elastic type cable drum 2 and linked to each other with seven core bearing cables 9 with well logging.Logger string 11 connects with seven core bearing cables 9 with well logging by halter 10.Elastic type cable drum 2 is arranged on can be along on the tower arm 3 reciprocating dollies 4.Halter 10 is fixedly mounted on the suspension hook 7 of pillar crane by suspender belt 8 and fastening devices.Move in a circle with tower arm 3 at logger string 11, perhaps follow dolly 4 and move back and forth along tower arm 3 directions, perhaps follow suspension hook 7 and hoist up and down together when moving, can avoid seven core cable 1 direct load.
Among the embodiment of the present utility model, well logging mainly is comprised of steel wire and seven cables with seven core bearing cables 9, and bend radius is larger.If it is enough large directly to be connected the diameter that just needs elastic type cable drum 2 with ground system by pillar crane, the while hoist and when tower arm direction is moved, can cause cable breakdown or with the problem such as crane rope clot.So the cable of embodiment of the present utility model on pillar crane replaces with common seven core cable 1.
Embodiment of the present utility model is when using, and the test signal that logger string 11 sends is transferred to ground receiving system by well logging with seven core bearing cables 9 and seven core cable 1 etc.
Example structure of the present utility model is simple, easy to use, in the instrument that hoists, can carry out transfer of data, can satisfy in 10 meters of the electromagnetic wave resistivity logging instrument radius of clean-up without metal (except directly over be used for the metal cord of transfer of data and lifting) operation requirements.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technician under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation in the details that reaches of implementing in form; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
