In the embodiment be more preferably, described in the oil gas wastewater efficient separation equipment be installed on oil well well head oil pipe seat also comprise rectification shell 2, described inward eddy coil pipe 10 is between described shell 1 and described rectification shell 2.
In the embodiment be more preferably, described in the oil gas wastewater efficient separation equipment be installed on oil well well head oil pipe seat also comprise medicament inlet pipe 17, described medicament inlet pipe 17 is also communicated to the inlet of described feed liquor energy-absorbing motor 8.
In the embodiment be more preferably, described in the oil gas wastewater efficient separation equipment be installed on oil well well head oil pipe seat also comprise friction-bar 16, the outer wall of described oil gas vent Taper Pipe 7 arranges described friction-bar 16.
In the embodiment be more preferably, described in the oil gas wastewater efficient separation equipment be installed on oil well well head oil pipe seat also comprise tubing hanger upper flange 15, the bottom of described shell 1 is connected on described tubing hanger upper flange 15.
In the embodiment be more preferably, described in the oil gas wastewater efficient separation equipment be installed on oil well well head oil pipe seat also comprise hanger 14, the top of described shell 1 is provided with described hanger 14.
During use, equipment is fixed on the tubing hanger upper flange of oil well well head; It is higher that liquid (oil gas sewage mixture) pressure is carried out in shaft bottom, two changes are produced: one is that higher pressure energy is changed into torque by motor after flowing into feed liquor energy-absorbing motor assembly 8, oil gas vent Taper Pipe 7 and loose liquid rotating cylinder 6 is driven to rotate (Northern Hemisphere for being rotated counterclockwise, for turning clockwise during the Southern Hemisphere); This change absorbs pressure reduction can be formed, and displaced the emulsifying power of oil gas sewage aggravation emulsification; Another one change is that the solution gas in the middle of oil gas water is separated out because pressure reduces, and causes oil gas sewage mixed volume to increase.
Foam-like oil gas sewage mixture volume expansion after change enters inward eddy coil pipe 10 fast, under the effect of internal spiral 21, create two motion states: one is the High Rotation Speed in coil pipe cross section, produce the elementary rotational flow separation effect of oil gas sewage; Another is along coil pipe axis direction, water body flow at high speed, and gas middling speed flows, oil body low speeds flow, cause oil or gas to prolong in journey migration process to be polymerized probability to increase, form the oil of obvious discrete, gas, sewage, it is oil and gas and water from the succession of primary separation process and in-depth.
The oil gas sewage emulsifiability of discrete is low, it rises to sparge pipe 12 along inward eddy coil pipe 10 rotation and sprays, be attached in loose liquid rotating cylinder 6 inner wall surface to be close to the mode of smearing, be centrifuged by the aperture on loose liquid rotating cylinder 6 and throw away, oil, gas, sewage present three kinds of states respectively, gas cannot be thrown out of because density is low, but upwards enters air cavity 3; Sewage be first thrown to shell 1 inner surface because density is maximum and under flow to water cavity 5 and store; And density crude oil placed in the middle can flow down slowly, is trapped in the oil phase section in the middle part of equipment; Material is thus formed the Distribution Pattern of gas, middle oil, lower sewage; And now loose liquid rotating cylinder 6 and oil gas vent Taper Pipe 7 are in integral-rotation state, the oil under the drive of friction-bar 16 in equipment, gas, sewage are in rotation status, make it abundant separation, the obvious interface of alternate formation.
The imbibition slot pipe 13 that oil gas vent Taper Pipe 7 upper position is set up is outlets of oil gas medium, and Open Side Down enters the import of discharge opeing gear pump assembly 9 along this for oil gas medium, and the equipment of being pumped out enters next stage flow process; Sewage then enters next stage handling process by outlet.
This technique avoids the intense impact emulsion occurred at production tree outlet decompression position, maintain the good existing discrete released state of oil gas sewage in down-hole string, and carried out meticulous separation further, therefore, this technique simplifies offshore oil platform oil gas sewage separating technology, make traditional oil gas sewage be separated huge device systems and greatly simplified, the size of platform can reduce, construction and maintenance cost are cut down greatly, and this technology has high promotional value.
