Abstract
A kind of Coreless drilling device for wire line core drilling, comprise outer tube and interior pipe, described interior pipe lower end is connected with interior drill bit, described outer tube lower end is connected with core bit by reamer, interior pipe is arranged in outer tube, inner and outer tubes are linked by bullet and connect, and interior pipe overcoat has centering ring, and centering ring is arranged at the inside of reamer; Described core bit is hollow, and interior drill bit is placed in core bit, and extends to the outside 2-3cm of outer drill bit.The beneficial effect that the utility model produces is, by arranging interior drill bit in the core bit of outer tube, make interior drill bit, core bit jointly form a solid bit body, core-drilling and the conversion not being in the mood for creeping into can be realized fast when not extracting drilling rod, when only extracting cord coring drill; Solve and can realize coring and the difficult problem not being in the mood for alternately creeping under not needing to remove drilling rod situation.
Description
Technical field
The utility model belongs to core drill technical field, is specifically related to a kind of Coreless drilling device for wire line core drilling.
Background technology
Wire line core drilling is named again does not propose brill core-drilling, and its feature is when rock core fills interior pipe, need not carry drilling rod and in drilling rod, interior pipe be fished for rope salvaging device obtaining rock core.Because of remarkable advantages such as its structure are simple, drilling efficiency is high, rock (ore deposit) heart taking rate is high, labour intensity is low, drilling cost is low, be widely used in oil well, coal bed gas well, shale gas well, coal survey the work of coring such as hole, hydrology hole.But in some areas, because rock (ore deposit) layer is very thick, do not need all to core, a needs part is cored and just can be met research or engineering demand; Or the layer bit interval that needs are cored is little, at this interval little (several meters to tens meters), but when needing repeatedly discontinuous coring, core-drilling cost creeps into far above not being in the mood for, and for cost-saving, general drilling of selecting changes drilling tool, drill bit, coring and alternately creeping between not being in the mood for creeping into, although this construction method saves single meter of drilling cost, frequent drilling reduces drilling efficiency, and integrated cost is increased greatly.Layer position, place of coring is darker, number of times of coring is more, the human and material resources caused because of drilling, time waste are larger, integrated cost increase is more, delay the duration simultaneously, be thus badly in need of a kind of device and solve in drilling process and do not need to remove drilling rod and can realize coring and the difficult problem not being in the mood for alternately creeping into.
Utility model content
The purpose of this utility model be to provide a kind of structure simple, can make in drilling process, not need to remove drilling rod and can realize coring and the Coreless drilling device for wire line core drilling not being in the mood for alternately creeping into.
For achieving the above object, the technical solution adopted in the utility model is, a kind of Coreless drilling device for wire line core drilling, comprise outer tube and interior pipe, described interior pipe lower end is connected with interior drill bit, and described outer tube lower end is connected with core bit by reamer, interior pipe is arranged in outer tube, inner and outer tubes are linked by bullet and connect, and interior pipe overcoat has centering ring, and centering ring is arranged at the inside of reamer; Described core bit is hollow, and interior drill bit is placed in core bit, and extends to the outside 2-3cm of outer drill bit.
Described interior drill bit is three-wing bit.
During use, the utility model coordinates existing cord coring drill to use, and carry out coring with when not being in the mood for alternately creeping at needs, the stage of coring adopts existing cord coring drill to carry out; When not needing to carry out extraction rock (ore deposit) heart, namely when employing is not in the mood for creeping into, change pipe interior in existing cord coring drill, outer tube and coupling part thereof into the Coreless drilling device for wire line core drilling of the present utility model, make inner and outer pipes synchronous axial system by the effect of bullet card, the interior drill bit that the core bit that outer tube is connected is connected with interior pipe realizes not being in the mood for creeping into jointly.
The beneficial effect that the utility model produces is, by arranging interior drill bit in the core bit of outer tube, make interior drill bit, core bit jointly form a solid bit body, core-drilling and the conversion not being in the mood for creeping into can be realized fast when not extracting drilling rod, when only extracting cord coring drill; Solve and can realize coring and the difficult problem not being in the mood for alternately creeping under not needing to remove drilling rod situation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of Coreless drilling device for wire line core drilling, comprise outer tube 1 and interior pipe 2, described interior pipe 2 lower end is fixedly connected with interior drill bit 6, described outer tube 1 lower end is connected with core bit 5 by reamer 3, and interior pipe 2 is arranged in outer tube 1, and interior pipe 2 and outer tube 1 are linked together by bullet card 7, interior pipe 2 overcoat has centering ring 4, and centering ring 4 is arranged at the inside of reamer 3; Described core bit 5 is hollow, and interior drill bit 6 is placed in core bit 5, and extends to the outside 2cm of core bit 5; Described interior drill bit 6 is three-wing bit; Core bit 5 and interior drill bit 6 are provided with multiple circle brill tooth 8.
During use, the utility model coordinates existing cord coring drill to use, and carry out coring with when not being in the mood for alternately creeping at needs, the stage of coring adopts existing cord coring drill to carry out; When not needing to carry out extraction rock (ore deposit) heart, namely when employing is not in the mood for creeping into, pipe interior in existing cord coring drill, outer tube and coupling part thereof are changed into the Coreless drilling device being used for wire line core drilling in the present embodiment, make interior pipe 2, outer tube 1 synchronous axial system by bullet card 7 effect, make core bit 5 and interior drill bit 6 jointly realize not being in the mood for creeping into.
The multi-level cored interval little at interval, only need extract cord coring drill back and forth, just can realize coring and be not in the mood for alternately to creep into, multiple trips is avoided to change drilling tool, drill bit, for 1000 meters of deep-wells, single drill pipe generally normal about 10 meters, on carry a drilling rod and generally need about 3 minutes, drilling once takes time: 100 × 3 minutes × 2 times=600 minutes (10 hours), the device used instead in the present embodiment only need put rope tool, then probably need 30 minutes, save the time greatly, save integrated cost.
