Abstract
The utility model discloses a formula oil pipe tip screw thread protector is dismantled to non - spiral, including two semicircle barrels and locking mechanism, the internal surface of two semicircle barrels is equipped with the interior screw thread with the screw thread looks adaptation of the oil pipe tip protected, two semicircle barrel locks are in the screw thread department of the oil pipe tip protected, two the semicircle barrels lockings of locking mechanism after with the lock. Owing to adopt foretell oil pipe tip screw thread protector, follow the ramp board and hoist to the rig floor, when taking out the jack rabbit and connect the stand to unload the thread protector, need not spirally bring or withdraw from oil pipe screw thread end completely into, only need one to break off with the fingers and thumb gently, just can lay down this screw thread protector, so it is very convenient to demolish this protector to improve the operating efficiency greatly, reduced operation personnel's intensity of labour and construction risk.
Description
Technical field
The utility model relates to oil gas and bores completion technique field, specifically a kind of oil pipe end thread protector.
Background technology
In HTHP completion and test jobs process; under must check the screw thread of each root oil pipe when entering flow string; with ensure under flow string between the sealing integrity of screw thread; thus meet perforation, for job requirements such as liquid, open flow, productions; therefore, before lower oil pipe operation, the thread protector protection for oil pipe thread particularly seems important.During lower oil pipe operation, the method generally adopted of oil pipe thread thread protector protection is at present: when oil pipe being winched to the semi girder of platform; and the oil pipe male and female end of thread thread protector of protection oil pipe is laid down by the mode to left-hand screw, afterwards oil pipe box and pin is cleaned and maintained.After cleaning maintenance is complete, by the mode to right-hand screw, thread protector is brought again the pin end of oil pipe.When playing oil pipe, rig floor uses single oil tube elevator to be winched on ramp plate by oil pipe, and drops into jack rabbit, afterwards oil pipe is winched to rig floor, lays down oil pipe thread protector and is taken out by jack rabbit, and puts on oil pipe thread protector and put by oil pipe in rig floor rat hole.After oil pipe being hung out rat hole by pipe elevator, lay down oil pipe thread protector, finally complete on oil pipe and buckle operation.Because thread protector got well by band on the pin end of oil pipe, effectively colliding with to screw thread in lifting operation can be prevented.The drawback of this method is: the first, and labour intensity is large, security risk is high.Different according to well depth, usually needed to repeat oil discharge pipe's thread protector action two or three hundred times, workman's continuous operation labour intensity is large, easily produces fatigue, if thread alternating even forgets that putting on thread protector is easy to cause oil pipe thread to damage on thread protector.Because spiral thread protector of laying down needs from the certain height of drilling floor surface, jack rabbit is easily caused to fall the accident of well; The second, operating efficiency is lower.Because this kind of thread protector is winching to rig floor or when putting into rat hole, especially easily making oil pipe thread protector tightlier from ramp plate, is difficult to be dismantled, when the depth of water, well depth by the time a large amount of for cost, causes the loss of expense.
Therefore; be necessary to study a kind of new oil pipe thread protective device; can in order to avoid dismounting protection oil pipe thread; need not spirally bring into completely or exit pipe wire end of thread during dismounting; only need one to break gently; just can lay down oil pipe thread protective device, while safeguard protection oil pipe thread, greatly save the time connecing oil pipe column, save production cost.
Utility model content
The purpose of this utility model be to provide a kind ofly to remove conveniently, non-helical detachable oil pipe end thread protector that operating efficiency is high, time saving and energy saving.
For achieving the above object, the technical scheme that the utility model adopts is:
Non-helical detachable oil pipe end thread protector; include two semicylindrical body and retaining mechanism; the inner surface of described two semicylindrical body be provided with suitable with the screw thread of protected oil pipe end in screw thread; described two semicylindrical body are fastened on the screw thread place of protected oil pipe end, and described retaining mechanism is by two semicylindrical body lockings after fastening.
Further, the bottom of described two semicylindrical body all radially, is stretched to outer and is had semicircular flanges, and the joint of two semicircular flanges is provided with flange retaining mechanism, and semicircular flanges is locked by described flange retaining mechanism.
Further, the internal diameter after described two semicylindrical body fastening becomes large by one end gradually to the other end.
Further, described two semicylindrical body adopt plastic cement material.
Further, described retaining mechanism and flange retaining mechanism all adopt carbon steel material.
The beneficial effects of the utility model: owing to adopting above-mentioned oil pipe end thread protector; from ramp plate lifting to rig floor; take out jack rabbit and connect column unload thread protector time; need not spirally bring into completely or exit pipe wire end of thread; only need one to break gently, just can lay down this thread protector, therefore it is very convenient to remove this protector; and substantially increase operating efficiency, reduce labour intensity and the construction risk of operating personnel.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, semicylindrical body; 2, retaining mechanism; 3, interior screw thread; 4, protected oil pipe; 5, semicircular flanges; 6, flange retaining mechanism.
Detailed description of the invention
As shown in Figure 1; non-helical detachable oil pipe end thread protector; include two semicylindrical body 1 and retaining mechanism 2; the inner surface of described two semicylindrical body 1 be provided with suitable with the screw thread of protected oil pipe end in screw thread 3; described two semicylindrical body are fastened on the screw thread place of the end of protected oil pipe 4, and two semicylindrical body 1 after fastening are locked by described retaining mechanism 2.
Further, the bottom of described two semicylindrical body 1 all radially, is stretched to outer and is had semicircular flanges 5, and the joint of two semicircular flanges 5 is provided with flange retaining mechanism 6, and semicircular flanges 5 is locked by described flange retaining mechanism 6.Described retaining mechanism and flange retaining mechanism all adopt carbon steel material.
Further, the internal diameter after described two semicylindrical body 1 fastening becomes large by one end gradually to the other end.
Described two semicylindrical body 1 adopt plastic cement material.
Operating principle: when the well completing test stage needs lower oil pipe operation, the complete oil pipe data of thread protector amount are laid down and after making a record at ramp plate, bring this non-helical detachable oil pipe end thread protector, after using rig floor winch to winch to rig floor, only need draw loose locking device, after taking out oil-pipeline path-ventilating gauge, tension retaining mechanism; After oil pipe is put into rat hole, to sling oil pipe with pipe elevator, again draw loose retaining mechanism, do not need spiral just can exit oil pipe thread completely.
The above is preferred embodiment of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
