具体实施方式 detailed description

[0018] 下面结合具体实施例和附图对本发明作进一步说明,但不应以此限制本发明的保护范围。 [0018] The following embodiments in conjunction with specific embodiments and drawings the present invention is further illustrated, but should not be used to limit the scope of the present invention.

[0019] 参考图1至图3,本实施例的复合式铁钻工和泥浆防喷盒包括:铁钻工11、泥浆防喷盒12、连接销轴13、油缸14和油缸销轴15。 [0019] Referring to FIG. 31, the composite according to the present embodiment of the iron roughneck and mud blowout preventer cartridge comprising: an iron roughneck 11, BOP slurry box 12, the connection pin 13, cylinder 14 and the cylinder pin 15. 泥浆防喷盒12包括:盒体21、密封件22、密封条23和由壬24。 BOP slurry box 12 comprising: a cartridge body 21, seal 22, seal 23 and the union 24.

[0020] 其中,盒体21包括两个相互配合的半盒体,本实施例中是两个半圆柱体,但并不限于此。 [0020] wherein, the cartridge 21 comprises two cooperating half cassette, in the present embodiment are two semi-cylindrical embodiment, but is not limited thereto. 相应地,密封件22是两个半圆板,安装在两个半圆柱体的顶部和底部。 Accordingly, the sealing member 22 are two semi-circular plates, mounted at the top and bottom halves of the cylinder. 更加具体而言,泥浆防喷盒2的两个半圆柱体内部上下安装有半圆环形密封22,两个半圆柱体两侧接缝处安装有密封条23,由壬24固定在盒体21的两个半圆柱体其中一个上。 More specifically, the two half-boxes BOP mud inside the cylinder 2 is attached to the upper and lower semi-annular seal 22, two half-cylinders are mounted on both sides of the seam seal 23, union 24 is fixed to the cartridge body 21 wherein one of the two half-cylinders.

[0021] 更进一步而言,泥浆防喷盒盒体21的两个半圆柱体对称布置于铁钻工11夹钳钳口前端两侧,盒体21的两侧还各自安装有油缸14。 [0021] Still further, the cassette cartridge BOP mud two semi-cylinders 21 are arranged symmetrically to an iron roughneck 11 on both sides of the front end of the clamp jaws, on both sides of the cartridge body 21 is also attached to the respective cylinders 14. 将盒体21的一个半圆柱体通过连接销轴13固定在铁钻工11的夹钳钳口前端一侧,盒体21的另一个半圆柱体通过连接销轴13固定在铁钻工11的夹钳钳口前端另一侧。 The cartridge body 21 is a half-cylinder 13 through the connecting pin fixed to the distal end side of the clamping jaw of the iron roughneck 11, the other cartridge body half-cylinder 21 through the connecting pin 13 is fixed to the iron roughneck 11 the other side of the leading end clamp jaws. 两个油缸14的第一端通过第一油缸销轴251固定在铁钻工11夹钳钳口一侧,两个油缸14的第二端通过第二油缸销轴252分别和盒体21的两个半圆柱体连接。 Two cylinders 251 fixed to a first end 14 of the clamping jaw 11 by a first side of the iron roughneck pin cylinder, two cylinders of the second end 14 of the cartridge body 252 and two pin cylinder 21 through a second a semi-cylindrical connector. 由此,两个油缸14可以带动两个半圆柱体分别绕各自的连接销轴13转动。 Thereby, two drive cylinders 14 can be connected to two respective semi-cylindrical pin 13 rotates about the respectively.

[0022] 当铁钻工11准备进入操作位置前,泥浆防喷盒盒体21的两个半圆柱体在油缸14收缩带动下,围绕各自的连接销轴13转动打开;然后,铁钻工11向前移动,夹钳钳口进入操作位置,在完成卸卸扣后,铁钻工11后退一定距离,将泥浆防喷盒12带到操作位置;盒体21的两个半圆柱体在油缸14的伸出带动下,围绕各自的连接销轴13转动闭合,将钻杆包裹住,开始收集流出的泥浆。 [0022] When the preparation before the iron roughneck 11 to enter the operating position, the cartridge BOP mud two semi-cylindrical cartridge 21 in the drive cylinder 14 contracts around the respective connection pin 13 is rotated open; then, the iron roughneck 11 moves forward, the clamp jaws into the operating position, after completion of unloading shackle, iron roughneck 11 retracted a certain distance, the slurry box 12 to the operation position of the blowout preventer; two semi-cylindrical cartridge 21 in the cylinder 14 projecting driven around the respective connection pin 13 is rotated closed, the drill pipe wrap, begin to collect the slurry. 密封件22和密封条23确保所收集的泥浆不外泄。 Seal 22 and seal 23 to ensure that the collected mud is not compromised. 另外,泥浆防喷盒12中的泥浆通过由壬24的后接管线流进泥浆池。 Further, the cartridge 12 in the BOP mud flows into a mud pit through a mud after the takeover by the lines of union 24.

[0023] 如图4所示,在起钻操作时,泥浆防喷盒12是打开状态;结合图1至图3,铁钻工11的夹钥'完成卸扣后,铁钻工11退回,带动泥楽■防喂'盒12进入钻杆位置,油缸14推动盒体21的两个半圆柱体分别围绕各自的连接销轴13转动闭合(闭合后的结构请参见图2);闭合后,盒体21将上部钻杆31和下部钻杆32的连接分界面包裹在闭合的盒体21中(如图1和图3所示);之后,上部钻杆31提起,泥浆从分界面流出,由于有密封件22和密封条23的密封,泥浆被收集在泥浆防喷盒12之内,里面的泥浆通过由壬24的后接管线流到泥浆池里;之后,泥浆防喷盒12再次打开,铁钻工11前移,开始下一个起钻操作循环。 [0023] As shown in FIG. 4, when the tripping operation, mud blowout preventer 12 is open cartridge; Figs. 1 to 3 in conjunction with, iron roughneck 11 is sandwiched key 'after completion of the shackle, iron roughneck 11 retracted, ■ anti mud driven feed yue 'drill rod cartridge 12 into position, the cylinder 14 pushing the cartridge body 21 surrounding the two semi-cylinders are connected to a respective pin 13 to rotate the closure (closure structure after see Figure 2); after closing, the upper case 21 and lower drill rod 31 connected to the interface 32 is wrapped in a closed box body 21 (FIGS. 1 and 3); then, lift the upper drill pipe 31, the mud flows out of the interface, Since the sealing seal 22 and the sealing strip 23, the slurry is collected in the slurry box 12 of the blowout preventer, through which the slurry flows from the slurry 24 to take over the line nonyl pool; then, the cartridge 12 is opened again mud BOP , iron roughneck 11 forward, to begin the next cycle of operation from drilling.

[0024] 综上,本实施例的复合式铁钻工和泥浆防喷盒将原来相互独立的两个设备组合成为一个设备,即将泥浆防喷盒设备优化后安装在铁钻工设备上,原先泥浆防喷盒的结构被大幅度简化,在保证各自设备使用功能的前提下,将两种设备的总重量、总占用空间减少,为井口节省出了更多的安全操作空间。 [0024] In summary, the composite iron roughneck of the present embodiment and the embodiment of the original slurry BOP box two independent devices combined into one device, soon after the slurry optimized BOP cartridge mounted on an iron roughneck apparatus, the original BOP mud cartridge structure is considerably simplified, to ensure their function premise equipment, the total weight of the two devices, reducing the total space, a wellhead saves more space for safe operation.

[0025] 需要说明的是,虽然本实施例中的两个半盒体的形状是以半圆柱体为例进行说明的,但是本领域技术人员应当理解,半盒体的形状还可以是其他任何适当类型的形状,比如长方体,闭合后的盒体相应地也是长方体。 [0025] Incidentally, while the present embodiment the shape of the two cassette half is semi-cylindrical in the embodiment described as an example, and those skilled in the art will appreciate, the shape of the cassette half may also be any other suitable types of shapes, such as rectangular, closed after the cassette is accordingly rectangular.

[0026] 本发明虽然以较佳实施例公开如上,但其并不是用来限定本发明,任何本领域技术人员在不脱离本发明的精神和范围内,都可以做出可能的变动和修改,因此本发明的保护范围应当以本发明权利要求所界定的范围为准。 [0026] Although the preferred embodiments of the present invention disclosed in the above embodiments, but not intended to limit the present invention, anyone skilled in the art without departing from the spirit and scope of the invention, can be made possible variations and modifications, Therefore, the scope of the invention as claimed in the present invention should be defined by the scope of the subject claims.
