Abstract
The utility model relates to a wellhead device for the field of a seismic prospecting drill, which comprises a wellhead baffle plate (1), a nut (2), a lifting eye (3), a pin (4), a coaming (5) and a wellhead (6). The wellhead device is characterized in that the coaming (5) is fixedly connected with the wellhead (6), the lifting eye (3) is connected with the wellhead (6), the lifting eye (3) is together connected with the wellhead baffle (1) through the nut (2), and the pin (4) is traversed through the wellhead (6), thereby the connecting and the replacing of a drilling rod are rapid and convenient, safe and reliable, the verticality of forming wells is guaranteed, and problems of the jamming of a drilling tool and the like are completely solved, and safety hidden troubles are solved, simultaneously, the well baffle plate of the wellhead device is flexible, the assembly and the disassembly are convenient, the structure is simple, and processing and manufacture are easy, and the device can be replaced at any time, easily damaged parts are replaceable, and the cost is greatly reduced.
Description
Technical field:
The utility model oil seismic exploration rig field specifically, is a kind of wellhead assembly.
Background technology:
The wellhead assembly of rig has been born in the well-digging course of work and has been connect the effect of changing drilling rod, and provides the active scope degree of drilling rod rotation, guarantees that the shaping well is perpendicular to ground.The well head of rig part all is welded as a whole both at home and abroad at present, direct and the well head friction of drilling rod in the well-digging process, be used for controlling the scope of drilling rod, its scope is generally all very big, form inclined shaft easily or the bit freezing phenomenon occurs, well head is caused the damage that can not repair, reduce the application life of rig.
Summary of the invention
The purpose of this utility model is to provide a kind of wellhead assembly, and it makes wellhead assembly easier, also more reliable, the requirement of the verticality of the well that both guaranteed to be shaped, and the convertibility of accomplishing consumable accessory again prolongs application life of rig.
The utility model is achieved in that and comprises well head baffle plate, nut, hanger, pin, coaming plate, well head, and coaming plate is fixedlyed connected with well head, and hanger is connected with well head, and hanger links together by nut and well head baffle plate, and pin passes in the well head 6.
The number of well head baffle plate 〉=2.
Coaming plate and well head weld all around are together.
The number of hanger 〉=4.
Hanger is welded in the both sides of well head respectively.
The advantage of this device is: by two, flexible, removable well head baffle plate are installed at the rig well head, to the active scope degree of drilling rod standard in addition, avoid drilling rod and well head direct friction simultaneously, make rig work effect reach optimum state.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, coaming plate 5 and well head 6 weld all arounds form a well head together, and drilling rod passes from middle circular hole.Four hangers 3 are welded in well head 6 both sides respectively, by nut 2 part well head baffle plate 1 is linked together, the well-digging duration of work at first adopts an impactor, and this impactor diameter is greater than the diameter of well head baffle plate 1, so this moment is not when using well head baffle plate 1, with its upset in the past.Next adopt well head baffle plate 1 since first drilling rod, two well head baffle plates 1 are turned be buckled on the well head 6 and ring is lived drilling rod, guarantee that drilling rod rotates in the scope of the circle that two well head baffle plates 1 surround.When unloading drilling rod when drilling well finishes, pin 4 is passed well head 6 withstand drilling rod laterally, the verticality of drilling rod is guaranteed, also avoid direct and well head 6 direct friction of drilling rod, cause the damage that to repair.
By experiment with use proof, the utility model patent is a kind of easier, reliable wellhead assembly, makes to connect that to change drilling rod efficient and convenient, safe and reliable, has guaranteed the verticality of shaping well, has fundamentally solved problems such as bit freezing, has eliminated potential safety hazard.The well head baffle plate of wellhead assembly is flexible simultaneously, and easy accessibility is simple in structure, is easy to processing and manufacturing, can change it at any time, accomplishes the replaceable of consumable accessory, greatly reduces cost.
Claims (5)
