Abstract
The invention relates to the technical field of operation under pressure of high pressure oil-water wells, in particular to a continuous pumping oil rod device. A ring-shaped blowout preventer I, a single valve plate blowout preventer I, a traveling slip, a switch controller, a hollow lifting oil cylinder, a ring-shaped blowout preventer II, a single valve plate blowout preventer II, a lower platform, a switch controller and a triple ram preventer are sequentially connected from top to bottom; each switch controller comprises a shell; two rollers are arranged in each shell; each two corresponding rollers are connected with a radial arm; each two corresponding rollers are tightly attached to an in-well pumping cylinder body by two springs on the corresponding radial arm arranged outside the corresponding shell; and magnetic switches are arranged at one ends of the outside radial arms and detection plates are arranged at the other ends of the radial arms. The invention implements the effects that the positions of a coupling and a centering device can be automatically detected and related blowout preventer equipment is automatically shut down and started according to programs, implements switching automation of the equipment, prolongs the service life of a ring-shaped rubber core and greatly improves the construction timeliness.
Description
Technical field:
The present invention relates to a kind of high pressure oil water well working with pressure technical field, particularly one plays sucker rod continuously.
Background technology:
A current sucker rod operation is that dependence two little annular preventers of tubular play sucker rod, specifically there is following shortcoming: the position one, for rod collar cannot judge, so that playing bar speed must be slow, otherwise box cupling is firmly by annular rubber core, easily causes annular rubber core to wear and tear very fast; Two, the position for oil pumping rod centering device cannot judge, must be slow so that play bar speed, otherwise centralizer is firmly by annular rubber core, easily causes annular rubber core to wear and tear very fast; Three, time pressure is high, annular rubber core switch is comparatively slow, wastes time.
Summary of the invention:
The technical problem to be solved in the present invention is to provide an a kind of sucker rod continuously, the arrangement achieves the position automatically can detecting box cupling and centralizer, and the blowout preventer apparatus of opening and being correlated with automatically is closed according to program, realize facility switching automation, improve the application life of annular rubber core, substantially increase construction timeliness.Overcome the position that existing sucker rod operation cannot judge rod collar and centralizer, play bar speed slow, easily cause the deficiency that annular rubber core weares and teares.
The technical solution used in the present invention is: an a kind of sucker rod continuously, comprises annular preventer I, single valve plate preventer I, traveling slip, hollow hoist cylinder, annular preventer II, single valve plate preventer II, lower platform, triple ram preventer, also comprise two on-off controllers, annular preventer I, single valve plate preventer I, traveling slip, on-off controller, hollow hoist cylinder, annular preventer II, single valve plate preventer II, lower platform, on-off controller, triple ram preventer connects from top to bottom in turn, on-off controller comprises housing, enclosure interior is provided with two rollers, two rollers are connected with spiral arm, two rollers are tightly fitted by two springs be arranged on the spiral arm of the hull outside cylinder body that makes to pump in two rollers and well, on sidespin arm, one end is provided with magnetic switch outside, the other end is provided with detecting plate.
The invention has the beneficial effects as follows: the present invention installs the mode of on-off controller owing to have employed, thus there is the position automatically can detecting box cupling and centralizer, and the function of opening relevant blowout preventer apparatus is automatically closed according to program, realize facility switching automation, improve the application life of annular rubber core, save construction cost, substantially increase construction timeliness.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of on-off controller.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, an a kind of sucker rod continuously, comprises annular preventer I 1, single valve plate preventer I 2, traveling slip 3, hollow hoist cylinder 5, annular preventer II 6, single valve plate preventer II 7, lower platform 8, triple ram preventer 9, also comprise two on-off controllers 4, annular preventer I 1, single valve plate preventer I 2, traveling slip 3, on-off controller 4, hollow hoist cylinder 5, annular preventer II 6, single valve plate preventer II 7, lower platform 8, on-off controller 4, triple ram preventer 9 connects from top to bottom in turn, on-off controller 4 comprises housing 10, housing 10 inside is provided with two rollers, two rollers are connected with spiral arm, two rollers are tightly fitted by two springs be arranged on the spiral arm of the housing 10 outside cylinder body that makes to pump in two rollers and well, on sidespin arm, one end is provided with magnetic switch outside, the other end is provided with detecting plate.
When in well, sucker rod body diameter is less than 25.4mm, correct before magnetic switch and be detected plate and block, magnetic switch like this is in a kind of duty, is in closed condition at the preventer being arranged on on-off controller 4 top; When in well, rod collar passes through scroll wheel positions, because box cupling diameter is larger, roller is expanded to both sides, spiral arm outside housing 10 is also corresponding to be outwarded winding to both sides, now detecting plate is by the detecting location away from magnetic switch, and magnetic flux changes, and produces an electromagnetic pulse, thus switch operation is carried out to electromagnetic switch, the preventer being arranged on top will be opened.When box cupling is by scroll wheel positions, detecting plate resets into origin-location again, magnetic switch Controlling solenoid valve, makes top preventer be in closed condition again.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
