Abstract
The utility model relates to an underground blowout preventer clamp for petroleum unbalanced drilling, which consists of a clamp body (1), a camp strip (2) and a fastening bolt (5), wherein, the clamp strip (2) is wound around a sleeve pipe (4) one time and connected with the clamp body (1), one end of the clamp strip (2) is shaped like a hook and buckled and firmly fixed with one end of the clamp body (1), a screw thread hole is machined at the other end of the clamp strip (2), the fastening bolt (5) connects the clamp strip (2) with the clamp body (1) through the screw thread hole and an open slot on the clamp body (1), the clamp body (1) adopts a stamped steel plate, a thick projection is arranged at the middle part of the clamp body, and the thick projection is hollow so as to reserve a groove for a hydraulic looped pipeline (6) to pass. With the advantages of simple structure, light weight, low processing cost, safety and reliability, and easy field operation, the utility model can effectively prevent the hydraulic looped pipeline from being damaged in the course of lowering the underground blowout preventer as well as in the follow-up workings.
Description
Technical field
The utility model relates to the instrument of oil gas field under balance pressure drilling, the auxiliary usefulness of completion practice downhole hole-closure device, and particularly a kind of downhole hole-closure device clip belongs to the downhole tool class.
Background technology
Downhole hole-closure device is a kind of auxiliary equipment that can realize overall process under-balance drilling technology.The operating principle of downhole hole-closure device is to carry out hydraulic control by ground, drives the switch of downhole hole-closure device, packing or connection valve plate pressure up and down, thereby the overall process under-balance drilling operation in the realization drilling process.The hydraulic pressure looped pipeline is the unique pressure transmission channel that drives downhole hole-closure device work, therefore, goes at downhole hole-closure device that the protection to the hydraulic pressure looped pipeline just seems particularly important in well and the follow-up work.Generally speaking, hydraulic pressure looped pipeline and downhole hole-closure device are positioned at same well depth, and the hydraulic pressure looped pipeline often is exposed in the well in the conventional construction operation, and unfixing with sleeve pipe, can't avoid the hydraulic pressure looped pipeline to be without prejudice in being lowered to the sleeve pipe process; Though some well has brought into use the downhole hole-closure device clip that the hydraulic pressure looped pipeline is fixed on the sleeve pipe at present, thereby reach the purpose of protecting the hydraulic pressure looped pipeline both at home and abroad, there are defectives such as weight is big, processing cost is high, the scene is not easy to operate in the clip of design at present.
Summary of the invention
The purpose of this utility model is to provide a kind of downhole hole-closure device clip, this clip is simply light, can easily hydraulic pressure looped pipeline and sleeve pipe be fixed together at the scene, thus effectively avoid downhole hole-closure device be lowered to and follow-up work in the hydraulic pressure looped pipeline infringement phenomenon that causes.
For achieving the above object, the technical solution adopted in the utility model is: mainly be made up of clip body, clip bar, fastening bolt, the clip bar encloses around one along sleeve outer wall, and be connected with the clip body, clip bar one end is and colludes shape and interlock with colluding of clip body one end and fixing dead, the clip bar other end is processed with screwed hole, and fastening bolt is connected the clip bar by the open slot of the clip bar of this screwed hole and correspondence with clip body 1; The clip body is the steel plate drawing, and its middle part is thick projection, thick projection hollow, and for the hydraulic pressure looped pipeline leaves the groove that passes through, the one end is for holding suitable hook arrangement with colluding of clip bar, and the other end is an open slot; Along radially perk of sleeve pipe, an end of perk is suitable in the same way with the clip body at nearly clip bar terminal position for the end that the clip bar is processed with screwed hole, and the length of its perk end should be able to satisfy the bolt installation footprint.
Advantage of the present utility model is: simple in structure, in light weight, processing cost is low, safe and reliable and on-the-spot easy operating.
Description of drawings
Fig. 1 is the utility model structural representation.
Specific embodiments
The utility model is described in more detail below in conjunction with accompanying drawing 1.The utility model mainly is made up of clip body 1, clip bar 2, fastening bolt 5, clip bar 2 encloses around one along sleeve pipe 4 outer walls, and be connected with clip body 1, clip bar 2 one ends are and collude shape and interlock with colluding of clip body 1 one ends and fixing dead, clip bar 2 other ends are processed with screwed hole, and fastening bolt 5 is connected clip bar 2 by the open slot of the clip bar 2 of this screwed hole and correspondence with clip body 1; Clip body 1 is the steel plate drawing, and its middle part is thick projection, thick projection hollow, and for hydraulic pressure looped pipeline 6 leaves the groove that passes through, the one end is for holding suitable hook arrangement with colluding of clip bar 2, and the other end is an open slot; Along radially perk of sleeve pipe 4, an end of perk is suitable in the same way with clip body 1 at nearly clip bar 2 terminal positions for the end that clip bar 2 is processed with screwed hole, and the length of its perk end should be able to satisfy bolt 5 installation footprints.
Operating principle of the present utility model: during setting of casing; hydraulic pressure looped pipeline 6 is connected with downhole hole-closure device; simultaneously; the hydraulic pressure looped pipeline is close to sleeve pipe 4 external surfaces; at every casing coupling 3 places; the hydraulic pressure looped pipeline is fixed in clip body 1 groove; simultaneously; clip bar 2 one ends and clip body 1 are colluded extremely; the other end is connected with clip body 1 by fastening bolt 5, thereby the hydraulic pressure looped pipeline is fixed on every bushing outer surface, has avoided the hydraulic pressure looped pipeline to be subjected to axial infringement in going into well and follow-up work; reach protection hydraulic pressure looped pipeline, guarantee effective transmission of downhole hole-closure device driving pressure.
Claims (2)
1, a kind of downhole hole-closure device clip, mainly form by clip body (1), clip bar (2), fastening bolt (5), it is characterized in that: clip bar (2) encloses around one along sleeve pipe (4) outer wall, and be connected with clip body (1), clip bar (2) one ends are and collude shape and interlock with colluding of clip body (1) one end and fixing dead, clip bar (2) other end is processed with screwed hole, and fastening bolt (5) is connected clip bar (2) by the open slot of the clip bar (2) of this screwed hole and correspondence with clip body (1); Clip body (1) is the steel plate drawing, and its middle part is thick projection, thick projection hollow, and for hydraulic pressure looped pipeline (6) leaves the groove that passes through, the one end is for holding suitable hook arrangement with colluding of clip bar (2), and the other end is an open slot.
