At least one annular opening is formed in the casing, the inner mandrel penetrates through a through hole of the casing, an opening is formed in the inner mandrel, a bearing is located between the inner mandrel and the casing, the eccentric block is connected with the inner mandrel through a bolt in a welding or hinging mode, the turbine blade assembly is arranged on the outer surface layer of the inner mandrel, the bottom of the lower connector is connected with the sensor, and the sensor is connected with a ground control end through an electric cable. The underground deblocking device has the advantages that the underground deblocking device is matched with a jar in use, not only can solve the problem that a drill column or a drill head is blocked in the well drilling process, but also can solve the problem that an oil gas well production pipe column of large-diameter underground tools including a packer, a hydraulic anchor and the like is clamped, improves the deblocking success rate, and overcomes the shortcoming caused by singly using the jar.
Description
Technical field
The utility model relates to drilling and repairing well and salvages unfreezing technical field, relates in particular to a kind of down-hole release device.
Background technology
At present, in oilfield prospecting developing drilling process, because a variety of causes can cause drill string or drill bit, meeting card, is Treating Jammed Bit Accident, and in drill string, group connects fluid pressure type, mechanical type or mechanical liquid type bumper jar to realize the object of drill string or drill bit unfreezing conventionally.In addition, in Oil/gas Well manufacturing process, because a variety of causes also can cause the tubing string that comprises the major diameter downhole tools such as packer, hydraulic anchor, meet card, thereby cause stopping production.Therefore, must under comprise bumper jar fishing tool carry out fishing and will meet card tubing string and salvage to ground.Bumper jar can effectively solve lock of tool drilling to a certain extent, but success rate is lower.
Utility model content
The purpose of this utility model is exactly, in order to address the above problem, to provide a kind of down-hole release device, has the work of coordinated bumper jar, effectively solves drill string or drill bit and meet card, unfreezing success rate advantages of higher.
To achieve these goals, the utility model adopts following technical scheme:
A kind of down-hole release device, comprise shell, inner axis of heart, bearing group, eccentric block, turbo blade group, lower contact, sensor, cable, ground control terminal, shell is provided with at least one annular port, inner axis of heart is through the through hole of shell, inner axis of heart is provided with an opening, bearing group is between inner axis of heart and shell, eccentric block is by bolt, welding or be hingedly connected with inner axis of heart, turbo blade group is arranged in the extexine of inner axis of heart, lower contact bottom connecting sensor, sensor connects ground control terminal through cable.
Described bearing is ball bearing, fluid bearing or jewel bearing.
Described flow control device can selective actuation underground vibrating instrument, adopts mechanical stuff, valve control mode or radio frequency recognizing electronic label control mode.
The beneficial effects of the utility model: the utility model coordinates bumper jar to use, not only can solve drill string or drill bit chance card problem in drilling process, but also the Oil/gas Well flow string that can process major diameter downhole tools such as comprising packer, hydraulic anchor is met a card difficult problem, improved unfreezing success rate, for follow-up construction is provided convenience.
Accompanying drawing explanation
Fig. 1 is the utility model structure cross-sectional schematic;
Fig. 2 is the utility model structure schematic top plan view.
Wherein, 1. top connection, 2. shell, 3. inner axis of heart, 4. bearing group, 5. eccentric block, 6. flow control device, 7. turbo blade group, 8. lower contact, 9. annular port, 10. opening, the extexine of 11. inner axis of heart, 12. sensors, 13. cables, 14. ground control terminal.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is elaborated:
The utility model comprises top connection 1, shell 2, inner axis of heart 3, bearing group 4, eccentric block 5, flow control device 6, turbo blade group 7, lower contact 8, sensor 12, ground control terminal 14.Shell 2 is provided with at least one annular port 9, for entering pit shaft, the drilling fluid of the turbo blade group 7 of flowing through provides passage, inner axis of heart 3 is through the through hole of shell 2, that the drilling liquid flow that pumps into from ground is through passage of the present utility model, inner axis of heart 3 is provided with an opening 10, for the interior part drilling liquid flow of inner axis of heart 3 provides passage to turbo blade group 7, thereby can drive inner axis of heart 3 to rotate around axle A, bearing group 4 is between inner axis of heart 3 and shell 2, described bearing group 4 is ball bearings, fluid bearing or jewel bearing, can allow inner axis of heart 3 to be independent of shell 2 rotations, eccentric block 5 passes through bolt, welding or be hingedly connected with inner axis of heart 3, can around axis A, rotate together with inner axis of heart 3, the centrifugal force that eccentric block 5 rotations produce causes radially of the present utility model or axial vibration, thereby cause drill string, the major diameter downhole tool vibrations such as the packer in drill bit or flow string, turbo blade group 7 is arranged in the extexine 11 of inner axis of heart 3.Flow control device 6 can selective actuation down-hole release device, with mechanical stuff, valve control mode or radio frequency recognizing electronic label control mode, control the flow of the drilling fluid of flow through inner axis of heart 3 and turbo blade group 7, thereby control the rotary speed of inner axis of heart 3 and eccentric block 5, then control vibration frequency of the present utility model, lower contact 8 bottoms are sensor 12, while there is bit freezing, the signal producing feeds back to ground control terminal 14 through cable 13, staff by analysis, determines whether whether unfreezing and unfreezing complete.
During construction, the utility model is directly connected with drill bit or fishing tool, or is connected with drill bit or fishing tool by drill string.Drilling fluid is pumped to the utility model by drilling rod, enters inner axis of heart 3, and inner axis of heart 3 transmission drilling fluids pass through the utility model.While there is bit freezing, the signal of generation feeds back to ground control terminal 14 through cable 13, and staff by analysis, determines whether unfreezing.Simultaneously, flow control device 6 can selectively be started, thereby transfer part drilling fluid is by the opening 10 turbo blade group 7 of flowing through, cause inner axis of heart 3 and eccentric block 5 rotations, the centrifugal force producing causes radially of the present utility model or axial vibration, then cause the major diameter downhole tool vibrations such as packer in drill string, drill bit or flow string, thereby make to meet the major diameter downhole tool unfreezings such as packer in drill string, drill bit or the flow string blocking.Drilling liquid flow is after turbo blade group 7, and the annular port 9 by shell 2 enters pit shaft.Through sensor 12, feed back to the signal of ground control terminal 14, if unfreezing completes, get final product shutoff device.
It should be noted that, in drill string or in fishing string, can comprise a plurality of the utility model, can be arranged in as required the different degree of depth, thereby can vibrate selectively the different piece of drill string or fishing string.In addition, when one of them the utility model lost efficacy, can use other the utility model vibration drill string, therefore improve the reliability of drill string or fishing string.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
