When mud rifle needs to safeguard, upper slips and lower slips being taken apart, upper cone just can be analyzed to two and half
Tubular structure, mud rifle can take out.
The upper cone of mud drill gun tool and the vertical dimension of lower cone diameter maximum are 0.8 meter, are so
Exciting of mud rifle provides enough gas expansion spaces.
A kind of mud drill gun tool process, containing following steps；Install mud drill gun tool with marsh buggy be
The mud gun epicenter system of carrying platform moves to assignment point, under the driving of rig, this drilling tool to
After lower boring arrives designated depth, mud rifle starts to excite for the first time.Mud rifle is excited to discharge for the first time
Pressure-air effect under, define more firm well head space between two cones, excite for second time
Ready.Second time excites and drive instrument is carried out seismic data recording, after record, rig
Being proposed from well head by this drilling tool, mud gun epicenter system moves to next assignment point, thus complete
Become one action circulation.
It is an advantage of the invention that and can once complete the well of drilling well and mud rifle excites, life is greatly improved
Produce efficiency.Unique bicone structure is effectively prevented the well head in high sediment concentration region and caves in, and improves
Stimulation effect.The mud gun epicenter system being made up of this drilling tool has expanded its operating area so that it is permissible
Well in marsh, the region job such as sea, beach intermediate zone, efficiently solve this regional exploration construction problem.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, it is possible to more completely preferably
Understand the present invention and easily learn the advantage that many of which is adjoint, but accompanying drawing described herein is used for
A further understanding of the present invention is provided, constitutes the part of the present invention, the schematic enforcement of the present invention
Example and explanation thereof are used for explaining the present invention, are not intended that inappropriate limitation of the present invention, such as figure wherein:
Fig. 1 is the structural representation of the present invention.
Fig. 2 is that mud drill gun of the present invention has internal structure schematic diagram.
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Detailed description of the invention
Obviously, the many modifications and variations that those skilled in the art are done based on spirit of the invention belong to
Protection scope of the present invention.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of mud drill gun tool, specifically a kind of for containing sand
Measure higher marsh and intermediate zone area, sea, beach geophysical exploration device.
The distinguishingly condition in the regions such as marsh, sea, beach intermediate zone so that traditional work pattern cannot be constructed.
Traditional work pattern is analyzed by the present invention, in conjunction with construction ground condition, has invented a kind of mud drill gun tool,
This device uses bicone structure, while realizing creeping into operation, it is possible to synchronously complete mud rifle and excite
Operation, can apply well in this region, efficiently solves this regional exploration construction problem.
Fig. 1 show mud drill gun tool, this drilling tool by upper cone 1, mud rifle 2, drill rod connector 3, on
Slips 4, lower slips 5, gas outlet 6 and lower cone 7 form, and mud rifle 2 is arranged in mud drill gun tool
Face.Fig. 2 show mud drill gun tool schematic internal view.
As it is shown in figure 1, the screw thread of drill rod connector 3 is standard drill pipe screw thread, can be with the standard of rig
Drilling rod connects.Drill rod connector 3 is fixed with upper cone 1 by upper slips 4.Upper cone and lower cone
Fix also by lower slips 5, thus form the agent structure of mud drill gun tool.As in figure 2 it is shown, mud rifle
Drilling tool is hollow structure, and upper cone 1 is made up of two halfpipe, and this halfpipe is by upper card
Watts 4 and lower slips 5 fixing composition hollow structure, mud rifle 2 is arranged in this hollow structure.At epicone
The gas outlet 6 corresponding with the QI KOU of mud rifle 2 is had, it is ensured that mud rifle 2 is released when exciting on the wall of body 1
The pressure-air put overflows from this gas outlet.When mud rifle 2 needs to safeguard, by upper slips 4 and lower card
Watts 5 take apart, and upper cone just can be analyzed to two halfpipe, and mud rifle 2 just can conveniently take out.
The upper cone 1 of mud drill gun tool and the vertical dimension of lower cone 7 diameter maximum are 0.8 meter, are so
Exciting of mud rifle 2 provides enough gas expansion spaces.When carrying out creeping into operation, upper cone 1
The silt that on it, well head caves in can be stoped to enter what the mud rifle formed between upper cone and lower cone excited
Expansion space, simultaneously because the vertical dimension of diameter maximum is less, thus ensures to a great extent
This well head space does not caves in.
When implementing operation, the mud gun epicenter system with marsh buggy as carrying platform installing mud drill gun tool is moved
Moving assignment point, under the driving of rig, this drilling tool is holed downwards after arrival designated depth, mud
Rifle starts to excite for the first time.Exciting under the pressure-air effect that mud rifle discharges for the first time, two cones
Between define more firm well head space, excite ready for second time.Second time excites and will carry
Dynamic instrument carries out seismic data recording, and after record, this drilling tool is proposed from well head by rig, mud
Rifle Seismic Source System moves to next assignment point, thus completes one action circulation.
Embodiment 2: as shown in Figure 1 and Figure 2, a kind of mud drill gun tool, the screw thread of drill rod connector 3
It is connected with the standard drill pipe of rig；Drill rod connector 3 is fixed with upper cone 1 by upper slips 4；On
Cone is fixed also by lower slips 5 with lower cone；Thus form the agent structure of mud drill gun tool；Mud rifle
Drilling tool is hollow structure, and upper cone 1 is made up of two halfpipe, and this halfpipe is by upper card
Watts 4 and lower slips 5 fixing composition hollow structure, mud rifle 2 is arranged in this hollow structure；At epicone
The gas outlet 6 corresponding with the QI KOU of mud rifle 2 is had on the wall of body 1.
When mud rifle 2 needs to safeguard, upper slips 4 and lower slips 5 being taken apart, upper cone just can be analyzed to
Two halfpipe, mud rifle 2 can take out.
The upper cone 1 of mud drill gun tool and the vertical dimension of lower cone 7 diameter maximum are 0.8 meter, this
Sample is that exciting of mud rifle 2 provides enough gas expansion spaces.
As it has been described above, embodiments of the invention are explained, but as long as substantially do not have
The inventive point and the effect that have the disengaging present invention can have a lot of deformation, and this is to those skilled in the art
For be apparent from.Therefore, such variation is also integrally incorporated in protection scope of the present invention
Within.
