Abstract
An oil well blowout simulator is composed of a nozzle shell, a O-shaped seal ring, a nozzle, a choke tube, a diffusion tube, bolts and nuts, which is characterized in that the nozzle shell is in a round pipe form, wherein two ends are provided with flanges, the middle is provided with a tangential port on circumference, one end is embedded with a nozzle along the central line, the outlet of the nozzle is extended to the inner port of the tangential port, whose two central lines are crossed, the another end is connected with the flange on the diffusion tube via bolts and nuts, the choke tube is arranged between the two flanges, the end of the nozzle shell embedded with the nozzle is connected with the outlet of a high pressure water pump, and the another end of the diffusion tube is connected with an oil production tree large four-way valve. The oil well blowout simulator can simulate oil well blowout, to provide conditions for designing blowout prevention devices and the test pressure quality inspection of blowout prevention devices.
Description
One, technical field
The utility model relates to a kind of analogue means, specifically a kind of simulation oil-well blowing device.
Two, background technology
Boring new well and workover treatment in oilfield development process is the key measure of safeguarding oil field ordinary production and volume increase stable yields, in its process gas blowout accident be the destruction measure implement and destroy oil reservoir be difficult to subdue " enemy ".Drilling well is got into high-pressure oil-gas layer blowout is easily taken place, it is that blowout takes place that the well workover kill-job does not press, connect the easy generation blowout of having broken of the well polished rod take out the band spray, for subduing blowout, the scientific research personnel has developed diversified blowout hookup, because gas stream ejection state blowout prevention effect unclear, that develop blowout hookup is not good enough during to blowout, moreover can't pressure testing and quality inspection to the blowout hookup of development yet.
Three, summary of the invention
The new purpose of this practicality provides a kind of simulation oil-well blowing device, for the development blowout hookup provides theoretical foundation, for the blowout hookup of developing provides pressure testing and quality inspection measure.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of nozzle housing, O-ring seals, nozzle, trunnion, anemostat and bolt and nut, it is characterized in that nozzle housing is made as tubular, two ends are provided with flange, the all sides in middle part are provided with one tangential mouthful, one end is inlayed a nozzle along center line, and jet expansion reaches tangential mouthful internal orifice place, and two center lines intersect, the other end links to each other with the anemostat flange by bolt and nut, is pressed with trunnion between two flanges; The end that nozzle housing is inlaid with nozzle links to each other with the high-pressure hydraulic pump outlet, and the other end of anemostat links to each other with Christmas tree big four joint.
Nozzle is made as taper shape, and import is dwindled gradually to outlet diameter, has 2 boss on the periphery of import department, and the diameter of top is big, and following diameter is little, studs with O-ring seals on little boss, and 2 set inner convex platforms of two boss and nozzle body cooperate.
Trunnion is made as cylindrical, two ends are provided with the undergauge boss and the set concave station corresponding matching of the flange on nozzle housing and the anemostat of symmetry, be made as the bell of tapered diameter in the import department of central through hole, below the outlet of bell, be made as one section not smooth holes of reducing, below the smooth holes outlet, be made as the bell in flaring footpath.
Anemostat is made as the conical pipe in flaring footpath, and two ends are provided with flange, with trunnion mutually the periphery of the import of platen press orchid be provided with concave station.
The utility model has solved the problem of modelling of blowout state, provides condition for designing lubricator and lubricator pressure testing quality inspection.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
1-nozzle housing 2-O shape sealing ring 3-nozzle 4-nut 5-packing ring 6-bolt 7-trunnion 8-anemostat A-high pressure chest B-low pressure chamber C-siphon port among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, do to describe in detail bright by embodiment below in conjunction with Figure of description:
The utility model is made up of nozzle housing 1, O-ring seals 2, nozzle 3, trunnion 7, anemostat 8 and bolt 6 nuts 4, it is characterized in that nozzle housing 1 is made as tubular, two ends are provided with flange, the all sides in middle part are provided with one tangential mouthful, one end is inlayed a nozzle 3 along center line, and jet expansion reaches tangential mouthful internal orifice place, and two center lines intersect, the other end links to each other with the anemostat flange by bolt 6 nuts 4, is pressed with trunnion 7 between two flanges; The end that nozzle housing is inlaid with nozzle links to each other with the high-pressure hydraulic pump outlet, and the other end of anemostat links to each other with Christmas tree big four joint.
The high pressure profit of high-pressure hydraulic pump supercharging enters nozzle 3 booster and speed-increasings and sprays from high pressure chest A, in nozzle housing, form low pressure chamber B, produce siphonage, air sucks for promptly tangential mouthful from siphon port C, oil gas water is mixed into trunnion 7 further to be mixed again through anemostat 8, Christmas tree big four joint, from big four ejection suitable for reading, form the blowout state, can change the pressure of high-pressure hydraulic pump, the blowout of imitation low pressure, several gas stream states of middle kill-job spray and high pressure blowout are found out the power point of spray power and the key position of blowout prevention, develop and be fit to height, in, the low-pressure preventer, and then with blowout device check blowout hookup quality.When the oil-well blowing analogue means is installed, necessarily connection is connected firmly, when especially trunnion being installed, must be connected firmly trunnion by nut 4, packing ring 5 and bolt 6, no seepage and no leakage guarantees the safety of construction, guarantees the analog-quality of oil-well blowing.
