Description
Technical field
The present invention relates to a kind of mud drill gun tool and process, belong to geophysical exploration technology field.
Background technology
In the transitional zone petroleum prospecting of sea, beach, traditional work pattern is first to hole with drilling tool, then mud rifle is placed in boring, excites mud rifle to complete exploration operation.Because the soft silt content of this region soil property is higher, implement when bore operation, drilling tool is proposed after wellhole easily cave in, be difficult for keeping, make to be like this placed in the mud rifle exciting in wellhole cannot be placed in, can not carry out mud rifle and excite operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention puies forward a kind of mud drill gun tool and process.
A kind of mud drill gun tool, the screw thread of drill rod connector is connected with the standard drilling rod of rig; Drill rod connector is fixed by upper slips and upper cone; Upper cone and lower cone are also fixed by lower slips; Thereby form the agent structure of mud drill gun tool; Mud drill gun tool is hollow structure, and upper cone is made up of two halfpipe structures, and this halfpipe structure fixedly forms hollow structure by upper slips and lower slips, and mud rifle is arranged in this hollow structure; On the wall of upper cone, have the gas outlet corresponding with the gas port of mud rifle.
When mud rifle need to be safeguarded, upper slips and lower slips are taken apart, upper cone just can be decomposed into two halfpipe structures, and mud rifle can take out.
The vertical range of the upper cone of mud drill gun tool and lower cone diameter maximum is 0.8 meter, like this for exciting of mud rifle provides enough gas expansion spaces.
A kind of mud drill gun tool process, contains following steps; The mud gun epicenter system taking marsh buggy as carrying platform that mud drill gun tool is installed moves to assignment point, and under the driving of rig, this drilling tool is holed downwards and arrived after designated depth, and mud rifle starts to excite for the first time.Under the pressure-air effect that excites for the first time mud rifle to discharge, between two cones, form comparatively firm well head space, ready for exciting for the second time.Excite for the second time drive instrument is carried out to seismic data recording, after record, rig proposes this drilling tool from well head, and mud gun epicenter system moves to next assignment point, thereby has completed one action circulation.
Advantage of the present invention is can once complete in the well of drilling well and mud rifle to excite, and has increased substantially production efficiency.Unique bicone structure has effectively prevented that the well head in high sediment concentration region from caving in, and improved stimulation effect.The mud gun epicenter system being made up of this drilling tool has been expanded its operating area, make its can be well in marsh, the region operation such as sea, beach transitional zone, efficiently solve this regional prospecting construction problem.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the present invention and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide a further understanding of the present invention, form a part of the present invention, schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention, as schemed wherein:
Fig. 1 is structural representation of the present invention.
Fig. 2 is mud drill gun tool inner structure schematic diagram of the present invention.
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment
Obviously the many modifications and variations that, those skilled in the art do based on aim of the present 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 the higher marsh of silt content and transitional zone area, sea, beach geophysical survey device.
The distinguishingly condition in the regions such as marsh, sea, beach transitional zone, cannot construct traditional work pattern.The present invention analyzes traditional work pattern, in conjunction with construction ground condition, invent a kind of mud drill gun tool, this device adopts bicone structure, when operation is crept in realization, can synchronously complete mud rifle and excite operation, can be applied in well this region, efficiently solve this regional prospecting construction problem.
Figure 1 shows that mud drill gun tool, this drilling tool is made up of upper cone 1, mud rifle 2, drill rod connector 3, upper slips 4, lower slips 5, gas outlet 6 and lower cone 7, and mud rifle 2 is arranged on mud drill gun tool the inside.Figure 2 shows that mud drill gun tool schematic internal view.
As shown in Figure 1, the screw thread of drill rod connector 3 is standard drill rod threads, can be connected with the standard drilling rod of rig.Drill rod connector 3 is fixing with upper cone 1 by upper slips 4.Upper cone and lower cone are also fixing by lower slips 5, thereby form the agent structure of mud drill gun tool.As shown in Figure 2, mud drill gun tool is hollow structure, and upper cone 1 is made up of two halfpipe structures, and this halfpipe structure fixedly forms hollow structure by upper slips 4 and lower slips 5, and mud rifle 2 is arranged in this hollow structure.On the wall of upper cone 1, have the gas outlet corresponding with the gas port of mud rifle 26, ensure that the pressure-air discharging when mud rifle 2 excites overflows from this gas outlet.When mud rifle 2 need to be safeguarded, upper slips 4 and lower slips 5 are taken apart, upper cone just can be decomposed into two halfpipe structures, and mud rifle 2 just can conveniently take out.The vertical range of the upper cone 1 of mud drill gun tool and lower cone 7 diameter maximums is 0.8 meter, like this for exciting of mud rifle 2 provides enough gas expansion spaces.In the time creeping into operation, the expansion space that the mud rifle that upper cone 1 can stop silt that on it, well head caves in to enter to form between upper cone and lower cone excites, simultaneously because the vertical range of diameter maximum is less, thereby ensure that to a great extent this well head space does not cave in.
While implementing operation, the mud gun epicenter system taking marsh buggy as carrying platform that mud drill gun tool is installed moves to assignment point, and under the driving of rig, this drilling tool is holed downwards and arrived after designated depth, and mud rifle starts to excite for the first time.Under the pressure-air effect that excites for the first time mud rifle to discharge, between two cones, form comparatively firm well head space, ready for exciting for the second time.Excite for the second time drive instrument is carried out to seismic data recording, after record, rig proposes this drilling tool from well head, and mud gun epicenter system moves to next assignment point, thereby has completed 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 is connected with the standard drilling rod of rig; Drill rod connector 3 is fixing with upper cone 1 by upper slips 4; Upper cone and lower cone are also fixing by lower slips 5; Thereby form the agent structure of mud drill gun tool; Mud drill gun tool is hollow structure, and upper cone 1 is made up of two halfpipe structures, and this halfpipe structure fixedly forms hollow structure by upper slips 4 and lower slips 5, and mud rifle 2 is arranged in this hollow structure; On the wall of upper cone 1, have the gas outlet corresponding with the gas port of mud rifle 26.
When mud rifle 2 need to be safeguarded, upper slips 4 and lower slips 5 are taken apart, upper cone just can be decomposed into two halfpipe structures, and mud rifle 2 can take out.
The vertical range of the upper cone 1 of mud drill gun tool and lower cone 7 diameter maximums is 0.8 meter, like this for exciting of mud rifle 2 provides enough gas expansion spaces.
As mentioned above, embodiments of the invention are explained, but as long as not departing from fact inventive point of the present invention and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection scope of the present invention.
