Abstract
The utility model provides a seismic exploration compound drilling drill rod, and belongs to the technical field of petroleum seismic exploration and coal-field seismic exploration. An outer tube female joint, an outer tube male joint and an outer center rod are welded to constitute an outer tube assembly; an inner ring, an inner center rod, an inner spiral piece, an inner connection tube and an inner female square body are welded to constitute an inner spiral rod; glyd rings are arranged on the inner ring of the inner spiral rod; the outer tube female joint and the inner ring are respectively provided with two ball grooves, and the outer tube assembly is connected with the inner spiral rod through the ball grooves, balls and set screws; the inner ring is of an outer square structure, and the inner female square body is of an inner square structure. The seismic exploration compound drilling drill rod has the advantages that the outer tube assembly and the inner spiral rod are designed in a clockwise or counter-clockwise rotation mode, relative speed of drilling cuttings is increased, and upward movement is accelerated; the problems that the drilling cuttings fall and cannot move upwards in unconsolidated formations during spiral drilling, and in sticky formations, the gap of the spiral piece is blocked and drilling is difficult are resolved; the frequency of the situation that the drilling cuttings and dust fly during general drilling is reduced, and pollution to drilling staff and equipment is lightened.
Description
Technical field
The utility model relates to a kind of seismic prospecting combined drilling drilling rod, belongs to oil seismic exploration, coal seismic prospecting technical field.
Background technology
It is the key link that improves the seismic acquisition imaging precision that loess tableland reaches the similarly assurance of layer region seismic prospecting drilling well depth of pore forming.Such area feature is: high slope, mountain is steep, and coombe spreads all over, and motor-driven drilling equipment can't be gone up a hill.And drought and water shortage, complex formation, soft or hard are alternately, and centre is mingled with mud, adhesive dried loess, rice glue mud and clay layer, so such regional exploration drilling is comparatively difficult.
Because lack of water can't adopt mud drilling technique; Therefore, generally adopt spiral drilling well, core drill well.Coring drill rod and core bit are used in conjunction with, and meet than hard formation and get the obstruction of core mouth, can't get core; Auger stem is met gummy formation, and drilling cuttings stops up the helical blade gap, creeps into difficulty, meet the scall drilling cuttings and fall, can not on the problem returned.
At present, Huangtuyuan area seismic prospecting construction adopts artificial luoyang spades, with tactics of human sea, guarantees construction speed, but this instrument runs into constructional difficulties of slip stone or old stratum, and the wellbore construction degree of depth can't guarantee.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of seismic prospecting combined drilling drilling rod, has both had the performance of getting core, has again an effect of auger stem, makes drilling cuttings return discharge on smoothly.The loess tableland that solves drought and water shortage reaches the similarly drilling well difficult problem of layer region.
A kind of seismic prospecting combined drilling drilling rod, be welded to form outer pipe assembly between outer tube female joint, outer tube male joint and outer intermediate bar; Be welded to form the inside spin bar between inner ring, interior intermediate bar, inner screwy fin, inner connecting tube and interior maternal; Glais ring is arranged on the inner ring of inside spin bar; Outer tube female joint and inner ring all have the twice ball grooves, and outer pipe assembly is connected the twice ball grooves and connects with ball and holding screw with the inside spin bar; Inner ring is outer tetragonal, and interior maternal is interior tetragonal.
The main effect of the utility model has three aspects::
1, outer pipe assembly and interior middle screw rod forward and backward design, increase the drilling cuttings relative velocity, returns in acceleration;
2, the chance scall drilling cuttings that solves in the spiral drilling well falls, can not on return; Meet gummy formation flight gap blocked, creep into the problem of difficulty;
3, reduce the scene that the conventional drilling drilling cuttings stirs up a cloud of dust, alleviated the pollution to drilling implementer and equipment.
Description of drawings
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not form improper restriction of the present utility model, as figure wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations done based on aim of the present utility model of those skilled in the art belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of seismic prospecting combined drilling drilling rod, be welded to form outer pipe assembly between outer tube female joint 1, outer tube male joint 3, outer intermediate bar 2; Be welded to form the inside spin bar between inner ring 8, interior intermediate bar 7, inner screwy fin 6, inner connecting tube 5 and interior maternal 4; Glais ring 9 is arranged on the inner ring 8 of inside spin bar.
Outer tube female joint 1 and inner ring 8 all have the twice ball grooves, after outer pipe assembly and inside spin bar assembly welding are completed, as figure, install, and aim at the twice ball grooves, ball and holding screw 10.
The outer tube pin and box sub of seismic prospecting combined drilling drilling rod and intermediate bar welded construction, external diameter is basic identical, and it is flat that two end joints all are milled with fork, for ease of dismounting outer tube male and female joint connecting thread, adopts pyramidal structure, and integral body is heat-treated.
The each several part of inside spin bar is welded construction, and for ease of dismantling in drilling process, inner ring 8 and interior maternal 4 are respectively outer four directions and interior tetragonal, and integral body is heat-treated.
The twice ball guarantees to rotate freely between outer pipe assembly and inside spin bar, and twice Glais ring 9 plays sealing function.
Main function: outer pipe assembly and the inside spin bar of seismic prospecting combined drilling drilling rod have respectively different power drives, outer pipe assembly dextrorotation, the inside spin bar is left-handed, and drilling cuttings is along the flight 6 of inside spin bar,, by returning on the gap between outer pipe assembly and inside spin bar, discharge well head.The outer pipe assembly protection borehole wall, be equivalent to get the core outer tube; The inside spin bar is equivalent to auger stem, returns discharge on the guiding drilling cuttings.
The structure of seismic prospecting combined drilling drilling rod, two drives structure of outer pipe assembly and inside spin bar; Use the Glais ring sealing in hermetically-sealed construction.Allow space also can adopt " O " circle and other hermetically-sealed construction forms according to drilling rod.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
