Abstract

The utility model provides a transmission tool for a through-drill-rod open-hole well logging instrument. The tool comprises a torpedo, a bypass, a headstall, a drill rod, a drill collar, a drill bit, a hanger drill collar, an upper hanger and a lower hanger, wherein the hanger drill collar is connected to the bottom of the drill rod or the drill collar; the drill bit can be connected to the bottom of the hanger drill collar; the drill rod descends to a predetermined logging position of an oil well; a well logging instrument string is formed by assembling the headstall, the upper hanger, the lower hanger and a well logging instrument in sequence on the ground and is arranged inside the drill rod; a well logging cable is connected with the torpedo; the torpedo penetrates through the bypass, enters the drill rod and is connected with the headstall; the bypass is connected with the uppermost end of the drill rod. According to the tool, an open-hole well can be directly logged in a well drilling trip-out process, so that the well logging time is effectively shortened, and the construction accident risk is reduced.

Description

Cross drilling rod open-hole logging instrument delivery means

Technical field

The utility model relates to petroleum exploration field, relates in particular to a kind of drilling rod open-hole logging instrument delivery means of crossing.

Background technology

In oil well logging, open-hole logging is mainly used in test and bores stratum relevant parameter after completion, oil open-hole logging in the past, drilling rod, drill collar and drill bit all need to be tripped out to well, then by cable, connect instrument string and transfer to assigned address and propose well logging, if the bad instrument of hole condition can not be transferred, need to again creep into down the well that works, after drifting is complete, drilling rod, drill collar and drill bit be tripped out to well again, again transfer instrument and log well.Because the trip time is oversize, so logging efficiency is very low, holding time is long, and the hole condition fortuitous event such as easily collapse.

Utility model content

The purpose of this utility model is the above-mentioned shortcoming existing in prior art in order to overcome, and a kind of drilling rod open-hole logging instrument delivery means of crossing is provided, and comprising: torpedo, bypass, head harness, drilling rod, drill collar, hang drill collar, on hang, under hang;

Described torpedo is that cable passes bypass and is connected with head harness;

Described bypass enters drilling rod inside for carrying cable for torpedo, and cable is connected to torpedo head;

Described head harness is that upper end connects torpedo, and hang on connecting lower end, provides and connect and the effect of cable transmission of signal;

Described drilling rod is that oil drilling is with transmitting twisting force;

Described drill collar is that oil drilling is with transmitting twisting force;

The described drill collar of hanging, comprising: hang urceolus, hang inner sleeve and form for the interior card of hanging of hanging on articulating;

On described, hang, comprise electric-motor drive unit for driving elastic claw, for the elastic claw hung on capturing, form for wireless outer shroud and the shell of wireless telecommunications;

Under described, hang, comprise with above hang elastic claw block and throw off under hang head, for wireless outer shroud, the shell of wireless telecommunications and hang piece and form;

Described drill bit, for passing through the customization drill bit of instrument string with centre bore.

Accompanying drawing explanation

Fig. 1 is that the utility model is at well head scheme of installation;

Fig. 2 is the utility model practical logging schematic diagram;

Fig. 3 is that the utility model is hung drill collar generalized section.

The specific embodiment

In order to make those skilled in the art person understand better the scheme of the embodiment of the present invention, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.

With reference to Fig. 1, be that the utility model passes through drill pipe tool well head installation drawing, comprise: cable 1, torpedo 2, bypass 3, head harness 4, drilling rod 5, on hang 6, under hang 7 and drill collar 8, hang drill collar 9 and drill bit 10.

Drilling rod 5, drill collar 8, hang drill collar 9 and drill bit 10 links together, transfer to assigned address, will.By head harness 4, drilling rod 5, on hang 6, under hang 7 and pertinent instruments at well head, connect, torpedo 2 tape cables 1 enter drilling rod inside by bypass 3, and torpedo 2 is connected with head harness 4, and whole string instrument is transferred to hanging drill collar 9 places.

With reference to Fig. 2, be that the utility model passes through drill pipe tool and logger well logging schematic diagram, comprise: cable 1, bypass 3, drilling rod 5, torpedo 2, head harness 4, drill collar 8, on hang 6, under hang 7, hang drill collar 9, drill bit 10, logger 11 and stratum 12.

Whole string instrument is transferred to hanging drill collar 9 places, under hang 7 with hang drill collar 9 and articulate by the conical surface or platform, now logger 11 stretches out outside drill bit 10, by on hang 6 with under hang 7 and carry out wireless telecommunications, after instrument is normal, on driving, hang power set, will on hang 6 elastic claws and under hang 7 disengagements, by torpedo 2, head harness 4, on hang 6 proposition drilling rods, on starting, propose drilling rod well logging.

When needs inspection apparatus state or when carrying to well head on instrument string, by head harness 4 with on hang 6 and be connected and be placed in drilling rod 5 well heads, torpedo 2 enters drilling rod 5 by bypass 3 and is connected with head harness 4, torpedo 2, head harness 4 and on hang 6 and drag together cable and hang 6 tops under arriving by gravity or mud pressuring method, by above hang 6 elastic claws with under hang 7 under hang head and carry out automatic capturing, and by hang 6 wireless interior rings with under hang 7 wireless outer shrouds and carry out wireless telecommunications inspection apparatus state or will on instrument, carry to well head.

With reference to Fig. 3, be that the utility model is hung drill collar generalized section, drill collar urceolus 13, hang inner sleeve 14 and hang interior card 15, in drill collar urceolus 13, be equipped with respectively from top to bottom and hang inner sleeve 14, hang interior card 15.
