Abstract
The utility model relates to a blowout control pipe with a movable hanging panel and a movable ladder for oil field wells and water well head, which is mainly composed of an oil pipe, a movable hanging panel, a ladder etc. The middle part of the oil pipe is provided with a double treadle type ladder, which is welded on the wall of the oil pipe by adopting the hinge form of double steel bar U-shaped structure. The upper part of the blowout control pipe is provided with a movable hanging panel, the hanging panel and a screw bolt is welded on a steel ring by a hinge, the steel ring is sheathed on the oil pipe, and a regulation hole is arranged on the hanging panel to hook a polished rod. The utility model is convenient in operation, safe and reliable, and raises the work efficiency when in use.
Description
Affiliated technical field
The utility model relates to the lubricator of adorning on oilfield, the well, particularly with the lubricator of movable ladder and link plate.
Background technology
Now the general ladder of the employed lubricator of oil field oil water well head is with three separated by a distance being welded on the lubricator tube wall of round steel.Be integral and can not draw in, the radius of gyration is big.When the operation personnel climb up lubricator, because being a round steel, the underfooting supports, and the another pin must coil lubricator also will put on the downhole probe that puts kilogram weight more than 20, and operation is very much hard, dangerous.
Summary of the invention
Big in order to overcome the existing lubricator radius of gyration, problems such as operation inconvenience.The utility model provides a kind of new-type lubricator, and ladder is movable gathering the in, adopts two round steel to be welded on the lubricator tube wall with the hinge form for " U " type.This lubricator is provided with being hooked on the polished rod that the link plate device can be convenient, flexible, plays lubricator not by the effect of stretch bending.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the B-B sectional drawing of Fig. 1.
Among the figure: 1, box cupling, 2, oil pipe, 3, hanging plate cycle, 4, pin, 6, link plate, 7, bolt, 8, ladder, 9, short tube, 10, the emptying short circuit.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, this new-type lubricator is by box cupling (1), oil pipe (2), link plate (6), ladder (8), emptying short circuit compositions such as (10), as Fig. 1, hanging plate cycle (3) side is welded with symmetry with holes two perpendicular band steels, be connected with link plate (6) with pin (4), can be welded by two band steels of symmetry and short tube (5) around the link plate (6) that pin (4) rotates, link plate is provided with adjustment hole above (6), wherein an adjustment hole is threaded, hang on the polished rod by bolt (7), as Fig. 2, play lubricator not by the effect of stretch bending.Be applicable to the test of annular space well head, double tube well head.
Ladder (8) is to be bent into " U " type with reinforcing bar, and an end is with short tube (9) and curves 90 ° of other ends and curve " U " type, and the joint butt welding has the semicircle round steel to support below, as Fig. 3, can rotate around short tube (9).
This new-type lubricator can be used for the blowout prevention of oil-field oil pumper annular space well head and double tube well head, also can be used for the blowout prevention of water injection well, oil flow production well well head.At work, easy to operate, safe and reliable, increase work efficiency.
Claims (3)
