Abstract
A spiral flow type oil and gas separation stable pressure tank for an oil and gas mixed conveying pump comprises a tank body, an oil inlet pipe and an oil outlet pipe; an oil inlet is arranged along the tangential direction of the outside peripheral surface of the tank body; an exhaust valve communicated with the interior of the tank body is arranged at the top end of the tank body; an oil outlet at the outer end of the oil outlet pipe is formed in the bottom of the tank body; the oil inlet in the inner end of the oil outlet pipe extends towards the interior of the tank body; the height of the extending pipe, in the tank, of the oil outlet pipe is higher than the oil inlet pipe. The spiral flow type oil and gas separation stable pressure tank for the oil and gas mixed conveying pump is reasonable in structure and stable in flow discharging, and the vibration of an oil pipeline is reduced.
Description
Technical field
The present invention relates to a kind of oil-gas mixed delivery pump surge tank, particularly rotary flow type Oil-gas Separation surge tank for oil-gas mixed delivery pump.
Background technique
In petroleum production process, because crude oil is to be collected by multiphase mediums such as oil, rock gases, when transporting to gathering station by mixing pump, the operating conditions of mixing pump has certain requirement to the air content in crude oil.When gas-liquid is excessive, when in oil, gas content is higher, mixing pump just can not normally be carried, and need to discharge too much rock gas in oil by voltage stabilizing knock out drum, reduces air content, to adapt to the transportation work requirement of mixing pump.The patent No. is that 200620068749.0 Chinese patent discloses a kind of oil gas stable pressure cylinder, this surge tank in the tangential setting of the outside circumference of tank body into and out of hydraulic fluid port, in practical work process, crude oil is under high speed rotary motion state, at outer pipe place change moving direction suddenly, tank body is certainly led to impact, and this has just caused vibration to oil transport pipeline, and also less stable of the flow of the surge tank of this structure.
Summary of the invention
For overcoming deficiency of the prior art, the invention provides a kind of rational in infrastructure, reduce oil transport pipeline vibration, go out to flow rotary flow type Oil-gas Separation surge tank for stable oil-gas mixed delivery pump.
For addressing the above problem, the technical solution used in the present invention comprises tank body, oil inlet pipe and oil outlet tube, filler opening is along the tangent direction setting of tank body outside circumference, on tank body top, be provided with and the outlet valve communicating in tank, oil outlet tube outer end oil outlet is located at tank base, the inner filler opening of oil outlet tube extends in tank, and in the tank of oil outlet tube, the height of extension tube is higher than oil inlet pipe.
In the tank of described oil outlet tube, between extension tube and tank body, be provided with stiffening rib.
Described is provided with adpting flange into and out of oil pipe outer end.
The outer end oil outlet of described oil outlet tube is for being horizontally disposed with.
On tank body top, establish outlet valve, in its tank body outside circumference, be tangentially provided with import, outlet is set at the bottom of tank, tank body inner outlet pipe extension is higher than import, and fixes by stiffening rib.During use, its inlet/outlet is interlinked with outlet, the oil field header import of mixing pump respectively.
The multiphase medium crude oil being transferred like this enters rotary flow type Oil-gas Separation surge tank for oil-gas mixed delivery pump along the tangent direction of tank body, form rotational flow, in logical through flowline tank, the filler opening of extension tube, to the oil outlet output that is arranged on tank base, enters oil field header again.This design, rotated flowing liquid produces Oil-gas Separation, outlet valve by top is discharged unnecessary gas, the exhaust pressure threshold values of outlet valve can be according to the operating conditions setting of mixing pump, the liquid air pressure of surge tank output is relatively stable, rate of discharge is more stable, thereby has reduced the vibration to pipeline, safer.Avoid the pulsation of multiphase medium caused flow, pressure because gas liquid ratio changes to cause the vibration of pipeline, also improved the situation of the internal flow of mixing pump.
In the tank of oil outlet tube, extend the mouth of pipe higher than crude oil oil inlet pipe, make to enter more reposefully in the header of oil field through the multiphase medium of eddy flow voltage stabilizing, improved the mobility status in pipeline.
For the ease of assembling, at inlet/outlet place, be respectively equipped with adpting flange, oil outlet tube is horizontally disposed with.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention one.
Fig. 2 is the structural representation of the embodiment of the present invention one.
In figure, be labeled as: 1 oil inlet pipe, 2 tank bodies, 3 oil outlet tubes, the bend pipe of 4 substantially horizontals, 5 adpting flanges, 6 supporting legs, 7 stiffening ribs, 8 outlet valves, extension tube in the tank of 9 oil outlet tubes.
Embodiment
Embodiment one
Rotary flow type Oil-gas Separation surge tank for oil-gas mixed delivery pump, comprise tank body 2, oil inlet pipe 1 and oil outlet tube 3, filler opening is along the tangent direction setting of tank body outside circumference, on tank body top, be provided with and the outlet valve 8 communicating in tank, oil outlet tube outer end oil outlet is located at tank base, the inner filler opening of oil outlet tube is to extending to form out extension tube 9 in the tank of pipe in tank, and in the tank of oil outlet tube, the filler opening height of extension tube, higher than oil inlet pipe, is provided with stiffening rib 7 between extension tube and tank body in the tank of oil outlet tube.Into and out of oil pipe outer end, be provided with adpting flange 5.The outer end oil outlet of oil outlet tube is crooked by substantially horizontal, facilitates transport pipe to be connected by flange with the bend pipe 4 of substantially horizontal.
During use, the outlet of its oil inlet pipe and mixing pump is interlinked.Like this, multiphase medium enters in surge tank with tangent direction from mixing pump outlet, under the centrifugal action producing at gravity, buoyancy and swirling motion, gas is constantly assembled rising, be flooded with tank body, when the super through flowline import of liquid level height, the interior extension tube of tank that crude oil overflow enters oil outlet tube enters oil outlet tube, by gas in outlet valve drain tank, control tank body internal pressure simultaneously, reach voltage regulation result.Liquid phase medium remains at going out on open height of mixing pump, guaranteed between mixing pump rotor and rotor, there is fluid-tight in the gap between rotor and pump chamber, the discharge side of mixing pump and the generation of the vapour lock in suction chamber have effectively been prevented, to guarantee that multiphase medium is under the effect of mixing pump, the pressure increasing process of realization from low pressure to high pressure, thus meet the requirement that multiphase medium all can be carried under the working condition of various gas liquid ratios.In addition, mixing pump at work, gaseous medium compression will produce a large amount of heat, and tank body enough large volume can effectively reduce the medium temperature entering in tank body, avoided the heat accumulation in compression process, and affect the sealing of mixing pump and normally operation, guarantee that the course of conveying of multiphase medium is steady, efficient, safety.
