Abstract
The utility model provides a novel special wrench for a wellhead, belonging to a tool for oil field production. The novel special wrench comprises a handle, wherein a downward connecting plate is arranged at the front part of the handle; and forward clamping boards are respectively fixed on the two sides of the lower part of the connecting plate. The novel special wrench for the wellhead has a simple and rational structure, convenience and reliability in application, and can be inserted from the side surface of a screw cap to clamp the screw cap; and therefore, the novel special wrench not only can be used for mounting and dismounting the screw cap on a wellhead sleeve four-way flange plate sealed by cement, but also can be used under normal conditions. In the operating process, the sealed cement does not need to be smashed, thereby reducing the labour intensity of workers, reducing the production cost and the working cycle.
Description
Technical field
The utility model provides a kind of field produces to use instrument, especially a kind of spanner.
Background technology
In production is recovered the oil in the oil field, owing to oil, gas, well well head are in the field, in order to guard against theft, usually with the pipe nipple sealing of cement with the well head four-way junction of casing.When the well head four-way junction of casing needs to change because of damage, the nut of connection well muzzle pipe four-way ring flange is disassembled.Existing well head special spanner must be inserted in and could use in use from well head cap nut top; When the gap between well head cap nut and the cement face during less than the thickness of well head special spanner; Just can not block nut; And big monkey wrench not only abrades operating personnel's finger easily firmly the time, also is not easy to be stuck on the nut, is difficult to the nut of mounting flange is tightened or lays down.This brings very big difficulty for regular maintenance and construction, and the cement that causes having to sealing is pounded, thereby has increased working strength of workers, has increased production cost and duty cycle.
Summary of the invention
The utility model technical problem to be solved is a kind of novel well head special spanner to be provided, to realize the installation and removal of the nut on the well head four-way junction of casing ring flange easily.
The utility model is achieved in that novel well head special spanner, and it has handle, and there is downward connecting plate the front portion of handle, and the both sides, bottom of connecting plate are fixed with clamp forward respectively.
Adopt the well head special spanner of said structure; Simple and reasonable, easy to use and reliable, can insert from the side of nut and block nut; Not only can be used for the installation and removal of the nut on the well head four-way junction of casing ring flange behind the cement sealing, also can under regular situation, use.During operation, cement that will sealing is pounded, thereby has reduced working strength of workers, has reduced production cost and duty cycle.
Description of drawings
Fig. 1 is the sketch map of the utility model structure.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the concrete structure of the utility model.
Shown in accompanying drawing, the novel well head special spanner of the utility model, it has handle 3, and there is downward connecting plate 2 front portion of handle, and the both sides, bottom of connecting plate are fixed with clamp 1 forward respectively.
The height of clamp can be less than the height of the nut on the well head four-way junction of casing ring flange.Like this, when the gap between nut and cement face is very little, also be easy to from the side clamp is stuck in the outside of nut.Downward connecting plate makes clamp and handle that certain alternate position spike arranged, and the upper and lower spacing between handle and the cement face is increased, and is convenient to operation.
After being stuck in nut between two clamps, side direction firmly can tighten or lay down nut on handle.During use, can also on handle, put afterburning thick stick,, also can use hammer hammering handle to increase the moment of rotating screw cap.
Because the specification of the nut on the well head casing flange dish is unified, therefore, spacing between two clamps and the adaptation of the specification of nut get final product.
