Description
Technical field
The utility model relates to a kind of oil field oil and gas multiphase flow equipment, particularly the mixed defeated device of a kind of gas-liquid-solid rotary flow type voltage stabilizing for oil and gas multiphase flow pump discharge.
Background technique
In petroleum production process, because crude oil is to be collected by the multiphase medium such as oil, rock gas, in the time transporting to gathering station by mixing pump, the operating conditions of mixing pump has certain requirement to the air content in crude oil.In the time that 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, because filler opening is tangential installation, percent opening on cylindrical shell is increased, make the aggravation of cylindrical shell geometric discontinuity, cause that perforate near zone stress is concentrated, make this position stress phase complexity, on cylindrical shell, cause local heavily stressed.Stress gradient is larger, thereby has had a strong impact on the bearing capacity of cylindrical shell, and this position very easily becomes the destruction source of equipment.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of structural stability, reduces oil transport pipeline vibration, goes out to flow the mixed defeated device of stable gas-liquid-solid rotary flow type voltage stabilizing.
For addressing the above problem, the technical solution adopted in the utility model is:
The voltage stabilizing of gas-liquid-solid rotary flow type mixes defeated device, comprise tank body, oil inlet pipe and oil outlet tube, oil inlet pipe is connected with tank body is orthogonal, oil inlet pipe end is along the bending of tank body circumferencial direction, oil outlet is located at tank base, oil outlet tube the inner extends to form filler opening to top in tank, and in the tank of oil outlet tube, the height of extension tube is higher than oil inlet pipe.
Be provided with and the pressure gauge communicating in tank on tank body top.
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.
When use, its inlet/outlet is interlinked with outlet, the oil field header import of mixing pump respectively.The multiphase medium being transferred forms rotational flow by import bend pipe, enter in three-phase cyclonic voltage stabilizer, again by exporting mouth of pipe output in tank body, enter oil field header, avoid the pulsation of multiphase medium caused flow, pressure because gas liquid ratio changes to cause the vibration of whole petroleum pipeline, also improved the situation of the internal flow of front end mixing pump.
Import, lower than the structure of outlet, makes to enter more reposefully in the header of oil field through the multiphase medium of eddy flow voltage stabilizing, has further improved the mobility status in pipeline, and can prevent that in the time that medium gas liquid ratio is higher in tank, gas is communicated with formation vapour lock with pump.
For the ease of assembling, be connected with respectively flange into and out of mouth of pipe place, and the output mouth of pipe connects lap joint flange.
Oil inlet pipe is fixedly connected with tank body is orthogonal, makes easy processing, structure more reliable, has reduced stress and has concentrated, and the overall structure stressing conditions of tank body is improved greatly, has improved the structure stability of tank body.
Be provided with pressure gauge at tank body top, for detection of tank internal pressure.
This voltage stabilizing mixing pump is to utilize the gas self producing to carry out voltage stabilizing, the volume of dynamic adjustments tank body upper gas effectively, make voltage regulation result always in preferable states, effectively improve the operating mode of oil field header, the efficiency and the Safety performance that have improved oil and gas multiphase flow, reduced environmental pollution.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is embodiment one structural representation.
Fig. 2 is embodiment one plan structure schematic diagram.
In figure, be labeled as: 1 supporting leg, 2 outlet lap joint flanges, extension in the tank of 3 oil outlet tubes, 4 stiffening ribs, 5 gauge manifolds, 6 tank bodies, 7 oil inlet pipes, 77 oil inlet pipe end elbows, 8 suction flanges, 9 oil outlet tubes, the upper end filler opening of 10 oil outlet tubes.
Embodiment
Embodiment one
The voltage stabilizing of gas-liquid-solid rotary flow type mixes defeated device, comprise tank body 6, oil inlet pipe 7 and oil outlet tube 9, oil inlet pipe is connected with tank body is orthogonal, oil inlet pipe end 77 is along the bending of tank body circumferencial direction, oil outlet is located at tank base, oil outlet tube the inner extends to form filler opening 10 to top in tank, and in the tank of oil outlet tube, the height of extension tube 3, higher than oil inlet pipe 7, is provided with stiffening rib 4 between extension tube and tank body in the tank of oil outlet tube.
Be provided with and the pressure gauge communicating in tank on tank body top, pressure gauge is connected with in tank by the adapter 5 at tank body top.
Described is provided with adpting flange into and out of oil pipe outer end.
When use, by suction flange, input bend pipe is connected with the outlet of mixing pump, by outlet lap joint flange, output pipeline is connected with oil field header.Like this, multiphase medium is by mixing pump supercharging, enter the interior eddy flow that produces of tank body of rotary flow type three-phase mixed transferring voltage stabilizer through input bend pipe, under the centrifugal action producing at gravity, buoyancy and swirling motion, gas is constantly assembled the top liquid level top that rises to tank body 6, and in the time that liquid level height exceedes output tube 3, medium is discharged by output tube 3, the medium of assembling because of tank body top has compressibility, can cushion mixing pump pressure, the impact of flow pulsation on oil field header.
Liquid phase medium in tank remains at going out on open height of the front end mixing pump that is connected with filler opening, ensured between mixing pump rotor and rotor, gap fluid-tight between rotor and pump chamber, effectively prevent the generation of the vapour lock in discharge side and the suction chamber of mixing pump, to ensure that multiphase medium is under the effect of mixing pump, realize the pressure increasing process from low pressure to high pressure, thereby 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 can produce a large amount of heats, and tank body 6 enough large volume can effectively reduce the medium temperature entering in tank body 6, avoid 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.
