Description
Technical field
The invention belongs to the petroleum well logging technology field, particularly a kind of sidewall coring with the gear deixis is published device.
Background technology
The device of publishing of existing sidewall coring tool does not all have the gear deixis, and publish device and often occur that gear is stuck, gear entanglement phenomenon, like this, will cause the numbering (this numbering is by the gear decision of publishing device) and the numbering of design of the formation core of corer taking-up deviation to occur, thus the phenomenon that causes rock core and actual formation not to be inconsistent.Reduced core recovery.According to the data of grasping, the domestic device of publishing that does not also have to carry out at present the gear deixis, the producer that has has increased the gear deixis in ground instrument, but this indication is that ground instrument mails to the pulse voltage number that the device gearshift is published in the down-hole, can not publish the retaining number of the actual gearshift of device by authentic representative, be a kind of inaccurate indication.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and a kind of ground gear deixis that has is provided, can make operating personnel accurately know the actual gear of down-hole corer, reduce labor intensity of operating staff, reduce accounting for the well time, save the sidewall coring of the band gear deixis of material consumption and publish device.
For achieving the above object, the present invention is achieved in that
A kind of sidewall coring with the gear deixis is published device, and it comprises gearshift relay, shift switch and ignition transformer; Described gearshift relay drives shift switch and switches gear; Described shift switch is two a cuttves interlock band switch, and its A cutter connects contactless ignition, is used for the medicine cake of coring is lighted, and the B cutter connects the gear indicating section, is used for resistance value is sent to ground instrument; The secondary connection shift switch A cutter of described ignition transformer.
As a kind of preferred version, shift switch of the present invention is 36 interlocks of two cuttves band switch.
What the present invention owing to adopted had a gear deixis publishes the device structure, thereby has the function of gear indication.Improve the later device of publishing and to make operating personnel accurately know the actual gear of down-hole corer, avoided present gear unclear present situation, particularly down-hole to publish device and the situation that operating personnel blindly construct occurred disorderly after retaining, the block.The device of publishing after the improvement has reduced the probability that random retaining, block occur, even disorderly retaining, block phenomenon occur, operating personnel also can manually or automatically control gear on-off to specifying on the gear by monitoring gear numerical value, can avoid core barrel is penetrated wrong stratum, thereby improve core recovery.Quick manual or control gear on-off automatically to specifying on the gear is avoided core barrel is penetrated wrong stratum, the working time that this has shortened operating personnel to a great extent, reduced labor intensity of operating personnel, and reduced accounting for the well time, saved material consumption.
Description of drawings
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a schematic block circuit diagram of the present invention;
Fig. 2 is a physical circuit schematic diagram of the present invention.
Among the figure: 1 is top connection; 2 are top connection; 3 is the medicine cake; 4 is the contact; 5 is ignition transformer; 6 are top connection; 7 are top connection; 8 are the gearshift relay; 9 is shift switch; 10 are top connection.
The specific embodiment
Referring to shown in Figure 1, the sidewall coring of band gear deixis is published device, and it comprises gearshift relay, shift switch and ignition transformer; Described gearshift relay drives shift switch and switches gear; Described shift switch is two a cuttves interlock band switch, and its A cutter connects contactless ignition, is used for the medicine cake of coring is lighted, and the B cutter connects the gear indicating section, is used for resistance value is sent to ground instrument; The secondary connection A cutter of described ignition transformer; Described shift switch is 36 interlocks of two cuttves band switch.
The gear gauge tap that the present invention will publish device selects 1 switch to realize with two the tunnel 36, one way switch is used for ignition voltage is delivered to contactless ignition, another way switch then is the resistance that connects the indication that is used to shift gears, the moving position resistance value of switch revolution will increase 1k Ω, this resistance value is delivered in the ground instrument by cable and is indicated, finish the gear deixis, correctly publish.
The present invention publishes the composition of device:
Publish device and be made up of three parts, the relay of promptly shifting gears, shift switch, ignition transformer and skeleton line etc. are shown in accompanying drawing one.Wherein shift switch is the band switch of 36 interlocks of two cuttves, and what the A cutter connected is the contactless ignition of corer, is used for the medicine cake of coring is lighted, and what B connected is gear indication resistance, is used for resistance value is sent to ground instrument.
Operating principle (referring to Fig. 2):
(1) supplies with 1 pulse voltage of gearshift relay over the ground by top connection 2 cores, the gearshift relay will drive shift switch 1 gear of beating, if the cutter spacing indication is at the 2nd retaining, so, A cutter (some steel (for flint)) will be delivered to the output voltage of transformer secondary output on the 2nd contactless ignition, light the 2nd medicine cake, B cutter (indication cutter) is then delivered to the resistance of R1+R2 in the ground instrument by top connection 6 and 7 cable cores, the resistance of the R1+R2 that ground instrument is measured will be 2k Ω, and be shown to operating personnel, make operating personnel accurately know the gear of igniting.
(2) supply with 1 of igniting primary over the ground by top connection 1 core and exchange ignition voltage (short circuit over the ground of top connection 10 cores this moment), after transformer coupled, arrive on the secondary cutter, make the resistance wire heating of medicine cake, the ignition powder cake is correctly injected the stratum with core barrel.
(3) if shift switch block phenomenon, the gear indicated value in the ground instrument just can not change, and the situation of " think that the down-hole shifted gears, real well is still original gear down " just can not appear in operating personnel, just core barrel can not penetrated wrong stratum.
The gear deixis circuit of accompanying drawing 2, increase by one 36 and selected 1 band switch, 36 indication resistance have been increased, when the cutter of band switch refers at the 1st retaining, what be connected between top connection 6 cores and top connection 7 cores is resistance R 1, the resistance that R1 delivers in the ground instrument is 1k Ω, when the B cutter refers at the 2nd retaining, R1 connects with R2 (1k Ω), and the resistance that records on ground instrument is 2k Ω, and the like, so, by measuring the resistance value between top connection 6 cores and top connection 7 cores, can determine the position at A cutter place, thereby determine the position of igniting.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
