Simple structure, with low costs, operation and convenient to use and practicality are strong.
Description
Technical field
The utility model belongs to field of oil field oil extraction, relates to a kind of water injection well auxiliary equipment, especially water injection well blowout control equipment, specifically water injection well preventing spraying operation platform.
Background technology
Oil field does not have the technological means of comparative maturity in water injection well operation blowout prevention, anti-overflow both at home and abroad at present, the conventional well control device of general employing, namely ram preventer or Operating Pressure mode carry out job execution, can construct after needing well head step-down during the former operation, and cannot effectively control well head overflow in work progress, need post-processed; The latter can realize overall process blowout prevention, anti-overflow, but construction period is longer, maintainability reaches 20 days duty cycle, meanwhile operating expenses costly, Daqing oil field spilled petroleum applies first generation reducing blowout preventer in research in 2007, improve the blowout prevention of preventer, anti-overflow effect to a certain extent, but reducing blowout preventer exist in glue bucket life-span relatively short, the problem such as reducing is limited in scope, the technical requirements of existing equipment can not be met.
Summary of the invention
In order to solve the problem, the utility model proposes a kind of effect with blowout prevention, anti-overflow, effectively can reduce the job platform that wellbore fluid is arranged outward, its concrete technical scheme is as follows:
Water injection well preventing spraying operation platform, comprise rotary flange, described rotary flange is connected with single ram type perventer, single ram type perventer is connected with four-way, on four-way, relative both sides are connected with manual flat valve, and four-way is connected with waste collection groove, and waste collection groove is connected with butterfly valve, four-way upper end is connected with ball-type annular preventer, ball-type annular preventer is connected with load-bearing anti-jack slips group; Described rotary flange outside is provided with lower platform, and corner place, lower platform upper end is connected with four column lower ends, and four column upper ends are connected with upper mounting plate, and upper mounting plate is connected with guardrail.
Described lower platform is connected with level(l)ing device.
Described waste collection groove is connected with hydraulic energy storage device.
Described load-bearing anti-jack slips group adopts bi-directional slip group.
The beneficial effects of the utility model: on the basis of job platform, adopt ball-type annular preventer, single ram type perventer and load-bearing anti-jack slips group, realize preventing spraying operation; After being removed by former well head, install water injection well preventing spraying operation platform on four-way junction of casing top; In operation process, rely on ball-type annular preventer sealing oil sets annular space, adapt to different-diameter tubing string and remove; When ball-type annular preventer has fault to need repairing or changes, available single ram type perventer shut-in well; Adopt bi-directional slip group to substitute anti-jack slips and pipe elevator, tubing string upper top suddenly in operation process can be prevented, ensure safety work, can cancel again in lower tubular column process and switch pipe elevator operation, improve operating efficiency; Have also been devised waste collection groove in the bottom of operating platform, the sump oil sewage that operation process king-rod pipe racks goes out can be received, and squeeze into production main line by output pump, avoid landing pollution; Structure is simple, cost is low, operation and easy to use and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left side view of Fig. 1.
In figure: the upper guardrail of 1-, 2-load-bearing anti-jack slips group, 3-upper mounting plate, 4-hydraulic energy storage device, 5-ball-type annular preventer, 6-waste collection groove, 7-butterfly valve, 8-manual flat valve, 10-four-way, 11-single ram type perventer, 12-lower platform, 13-rotary flange, 14-tetra-column, 15-level(l)ing device.
Detailed description of the invention
For the ease of understanding, below in conjunction with Fig. 1 and Fig. 2, the utility model is further illustrated:
Embodiment 1: water injection well preventing spraying operation platform, comprises rotary flange 13, described rotary flange 13 is connected with single ram type perventer 11, realizes shut-in well; Single ram type perventer 11 is connected with four-way 10, on four-way 10, relative both sides are connected with manual flat valve 8, facilitate operated by personnel; Four-way 10 is connected with waste collection groove 6, for collecting the waste liquid of drippage or spilling in operation, preventing waste liquid to land and polluting; Waste collection groove 6 is connected with butterfly valve 7, so that the liquid in discharge waste collection groove 6; Four-way 10 upper end is connected with ball-type annular preventer 5, ball-type annular preventer 5 is connected with load-bearing anti-jack slips group 2; Described rotary flange 13 outside is provided with lower platform 12, and corner place, lower platform 12 upper end is connected with four column 14 lower ends, and four column 14 upper ends are connected with upper mounting plate 3, upper mounting plate 3 are connected with guardrail 1.
Embodiment 2: further, in order to the operation of staff better can be facilitated, described lower platform 12 is connected with level(l)ing device 15.
Embodiment 3: further, described waste collection groove 6 is connected with hydraulic energy storage device 4.
Embodiment 4: further, described load-bearing anti-jack slips group 2 adopts bi-directional slip group.
Beneficial effect: structure is simple, cost is low, operation and easy to use and practical; There is the effect of blowout prevention, anti-overflow, can effectively reduce wellbore fluid and arrange outward.
