Abstract
The utility model discloses an offshore oil lifting wellhead work platform, which is very suitable for use in a well site with a narrow work space, such as the well site of an offshore sea oil field cluster well. The work platform comprises a main work platform and an auxiliary work platform which are arranged below a wellhead blowout preventer, and the two work platforms are connected with each other and are supported by respective supporting mechanisms, thereby upraising construction operation area and expanding work space. The work platform is arranged below the wellhead blowout preventer and is supported by the supporting mechanisms, and thereby, the work platform is stable and reliable. The utility model upraises operation area, expands work space, solves the difficulty of narrow construction space, and reduces a plurality of unsafe factors to ensure the safety of operating personnel. Since the work space is expanded, the work efficiency is improved.
Description
Technical field
The utility model relates to the borehole operation accessory equipment of oil industry, and particularly Tan Hai oil field liftable shaft mouth operation platform is fit to the narrow and small well site of working space and uses, as the well site of Tan Hai oil field cluster wells group very much.
Background technology
The Tan Hai oil field adopts the cluster wells group to carry out oilfield exploitation more at present, because the limitation of well site condition causes with spacing between the well group well head less, simultaneously, in order to prevent the attack of storm tide, the well head of Tan Hai oil field oil, gas, well is generally higher, center-line-average is between 1.5-2.8m, and the operational space is narrow in the time of certainly will causing remedial work like this, brings many difficulties to workover operation construction.In the construction,, need use pipe, bar elevator to implement the lower tubular column operation then at the good blowout preventer of well head four-way upper flange surface installation capability in order to reach the well control requirement.Calculate from theoretical side, the height of dislodging suspension ring has increased 1.1m again during construction on the well head height, wherein the self-styled 0.05m of blowout preventer 0.6m+ pipe elevator 0.25m+ tubing collar 0.20m+.The height that unloads the hydraulic tongs that tubing string uses so will increase 0.6m on this basis again, and in view of this, the whole operation height has increased 1.7m on the well head height.Want under this environment, to construct near well head, to set up the people's operation that is used to stand well head rig floor 2-3.Because each sea, beach well group well head height, spacing differ, cause the rig floor of setting up to have the orientation and arrange inconsistent, there is not firm fixed form yet, it is wet and slippery to add well head, during construction, need the workmen to climb wet and slippery rig floor so high, like this continually, thereby bring very big potential safety hazard to construction.Cause thus that the well workover difficulty of construction is big, speed is slow, potential safety hazard is many, the accident of hurting sb.'s feelings often takes place, and according to statistics, the construction of per two mouthfuls of beach Hai Jing the scraping accident that caused by the rig floor reason will take place together.Based on above problem, a kind of liftable shaft mouth operation platform need be developed in the Tan Hai oil field, is used for the production scene.
Summary of the invention
The purpose of this utility model provides Tan Hai oil field liftable shaft mouth operation platform, solves the problem that the space is little, operation is difficult that narrow and small well site exists, and improves operating speed, improves the safe operation coefficient.
Technical solution of the present utility model is achieved in that Tan Hai oil field liftable shaft mouth operation platform comprises main job platform and by-effect platform, main job platform and by-effect platform are installed in the below of well head blowout preventer, two job platforms connect, support by separately supporting mechanism respectively, raise the constructing operation face, enlarged working space.
The utlity model has following advantage: job platform of the present utility model is installed in the below of well head blowout preventer, and the support of supporting mechanism is arranged again, and is solid and reliable.Raise the scope of operation, enlarged working space, solved the narrow and small difficult problem of construction space.Cut down many safety hazard, ensured the safety of operating personal.Because the expansion of working space has improved operating efficiency, other has following characteristics:
1, the utility model is designed to lifting mode, and adjustable height is applicable to the well head of differing heights.
2, flexibly connect with the angle steel bolt between main job platform and the by-effect platform, convenient in carrying is installed.

The specific embodiment
For further disclosing the technical scheme of the utility model job platform, in conjunction with being installed, example elaborates: referring to Fig. 1, Tan Hai oil field liftable shaft mouth operation platform comprises main job platform 2 and by-effect platform 3, main job platform 2 is connected with by-effect platform 3, is supported by supporting mechanism 7 and 8 respectively.The coupling end of main job platform 2 and by-effect platform 3 is provided with recess, and main job platform 2 can or be connected steel plate by angle steel with by-effect platform 3 and connect, and involutory latter two recess just in time below well head blowout preventer 4, is set up at well head casing nipple position.Referring to Fig. 2 and Fig. 3, main job platform 2 and by-effect platform 3 are framed structure, at the surperficial fixed flat planar or the steel mesh of framed structure.Supporting mechanism 7 is connected with by-effect platform 3 with main job platform 2 with 8 one ends, and other end design base is fixed major and minor job platform 2 and 3 respectively.Supporting mechanism 7 diagonal braces form stronger support to main job platform 2 between main job platform 2 and derrick base. Supporting mechanism 7 and 8 has following two kinds of structures, the first: supporting mechanism 7 and 8 is equipped with leading screw and sleeve, one rhizoid thick stick is installed in the sleeve, one end of leading screw or sleeve and main job platform 2 and by-effect platform 3 flexibly connect, the other end is supported on the ground, well site, rotate and main job platform 2 and by-effect platform 3 bonded assembly leading screw or sleeves, the i.e. height of scalable master job platform 2 and by-effect platform 3.It two is: supporting mechanism 7 and 8 is equipped with leading screw and sleeve, and two rhizoid thick sticks are installed in the sleeve, and two rhizoid thick sticks are packed into from the two ends of sleeve, and an end is connected with by-effect platform 3 with main job platform 2, and the other end is supported on the ground, well site.Be provided with handle hole on its sleeve, the operation thick stick is inserted or is screwed in the handle hole of sleeve, rotational sleeve can make leading screw lifting in the sleeve, regulates the height of main job platform 2 and by-effect platform 3.The supporting mechanism 7 and 8 that is located at main job platform 2 and by-effect platform 3 belows is provided with two covers at least.The side of main job platform 2 and by-effect platform 3 also is equipped with ladder 5 and 6, about the handled easily personnel, and as ladder 5 and 6 are not installed, also can be by take ladder or about derrick climbing temporarily.Main job platform 2 is connected with hanger bracket 1, and hanger bracket 1 is provided with and connects the arc groove, cooperates with two sides of main job platform 2 outer rim.Hanger bracket 1 is fixed on the derrick with main job platform 2 overlap joints, articulates or be connected, make the utility model more firm.
