Abstract
A blowout prevention protective barrel and fishing anchor belongs to the technical field of oil production engineering application. The blowout prevention protective barrel and fishing anchor solves the technical problem of overcoming the deficiencies in the blowout prevention technology. According to the technical scheme, a protective barrel is provided with a fishing threaded hole, the fishing threaded hole is provided with internal threads, and the circumference of the protective barrel is provided with liquid through holes; the lower end of the fishing anchor is provided with a fishing rod with external threads, the fishing rod is connected with a fishing anchor protective barrel through a pin, the fishing anchor protective barrel is laterally welded with a plurality of straighteners, and the upper end of the fishing anchor protective barrel is welded with a rotating handle. The blowout prevention protective barrel and fishing anchor has the advantages of being simple in structure and convenient to apply and obtains good anti-theft and anti-damage performance.
Description
Technical field
The utility model belongs to petroleum production engineering applied technical field, and what be specifically related to is that a kind of shut-in well is protected cylinder and drags for anchor.
Background technology
In oilfield process, have oil-water well and stop the situation of producing, at this moment need well to seal, the mode of shut-in well is to be lowered to blowout preventer in well, under oil gas water resistance every in down-hole, this mode has the operating mechanism that foreign material stop up blowout preventer, causing cannot deblocking in the time of need to driving a well in the future.
Summary of the invention
In order to overcome the deficiency of above-mentioned shut-in well technology, the utility model provides a kind of Novel sealing well protection cylinder and has dragged for anchor, after this protection cylinder input well is interior; be seated on blowout preventer; by shaft section all standing, in well, by people, dropped into after foreign material, can every living, can not enter in blowout preventer by protected cylinder.Because protection cylinder upper end is a plane, be convenient to foreign material to salvage, and protection cylinder self has the supporting anchor that drags for, and can salvage easily.
The technical scheme in the invention for solving the technical problem is: a kind of shut-in well protection cylinder with drag for anchor by casing, liquid-through hole, salvaging screwed hole, fishing rod, pin, drag for Anchor Care cylinder, centralizer body, rotary handle and form; casing is provided with salvaging screwed hole; salvaging screwed hole is internal thread; casing surrounding is provided with liquid-through hole; and drag for anchor lower end, be with externally threaded fishing rod; fishing rod with drag for pin between Anchor Care cylinder and be connected; drag for Anchor Care cylinder side direction and be welded with some centralizer bodies, drag for Anchor Care cylinder upper end and be welded with rotary handle.
The beneficial effects of the utility model are, this protection cylinder, with to drag for anchor structure simple application convenient, has good anti-theft and anti-damage performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, by 1 casing, 2 liquid-through holes, 3, salvaging screwed holes, 4 fishing rods, 5 pins, 6 drags for Anchor Care cylinder, 7 centralizer bodies, 8 rotary handles and forms.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind of shut-in well casing with drag for anchor by casing 1, liquid-through hole 2, salvage screwed hole 3, fishing rod 4, pin 5, drag for Anchor Care cylinder 6, centralizer body 7, rotary handle 8 form, casing 1 is provided with salvages screwed hole 3, salvaging screwed hole 3 is internal thread, casing 1 surrounding is provided with liquid-through hole 2, and drag for anchor lower end, be with externally threaded fishing rod 4, fishing rod 4 with drag for pin 5 between Anchor Care cylinder 6 and be connected, drag for Anchor Care cylinder 6 side direction and be welded with some centralizer bodies 7, drag for Anchor Care cylinder 6 upper ends and be welded with for rotary handle 8.
After shut-in well has operated, casing 1 is dropped in well, it drops on blowout preventer naturally; play a protective role. prevent that foreign material from falling into impact operation in the future in blowout preventer, when needs are salvaged, is lowered to and drags for anchor; by upper button direction rotation, drag for anchor, then go up bailing anchor and can trip out casing 1.
