Abstract
The invention is an oil-gas multiphase mixed input pump set inlet flow equalizer, characterized in that: a liquid collection flow dividing pipe is connected with the upper and lower ends of a gas-liquid separating pipe with inlet through exhaust pipe and liquid discharge pipe, respectively, the position in the liquid collection flow dividing pipe corresponding to the liquid discharge pipe is fixed with a sieve plate, the left side of the inner outlet of the liquid collection flow dividing pie is fixed with a weir plate, and there is a gap between the weir plate and the bottom of the liquid collection flow dividing pipe. And it can make all pumps in the parallel mixed input pump set operate on the optimum working condition that input gas flows and input liquid flows are equal respectively, effectively avoiding pump overheat damage caused by flow deviation.
Description
Technical field:
The present invention relates to a kind of oil gas field oil-gas gathering and transportation device, belong to a kind of oil-gas multi-phase mixed delivering pump inlet flow-harmonization device.
Background technique:
It is an international new technology that the oil gas supercharging mixes transferring technology, in recent years, has just begun to use in the exploitation of and offshore oil and gas field land in China.At present,, generally continue to use the header assignment of traffic mode that is suitable for infusion pump and gas transmission compressor, still do not go into implication, flow quantity uniform distribution device at parallel running oil-gas multi-phase mixed delivering pump specially mixing under the defeated parallel connection of pumps operating conditions.Header assignment of traffic mode has good applicability to carrying the supercharging equipment in parallel of single liquid or pure gas, can make the supercharging equipment of specification parallel running of the same race can both obtain identical inlet flow rate.And under the situation of transferring oil gas mixture, header assignment of traffic mode just can not be suitable at all.Because this method of salary distribution, the pump that can cause being arranged in the header upstream more aspirates the liquid of header, and the pump that is positioned at the header downstream can only aspirate a spot of liquid or whole intake-gas, thereby, make the pump in downstream can not get effective liquid lubrication and cooling, cause thermal damage occurred.In the actual production, the generation that mixes defeated pump damage accident in parallel causes mostly thus.
Summary of the invention:
In order to solve the problem that traditional gas, the single-phase supercharging equipment arrival manifold of liquid assignment of traffic technology can't adapt to the multiphase mixing transmission pump parallel running, the invention provides a kind of oil-gas multi-phase mixed delivering pump inlet flow-harmonization device, this oil-gas multi-phase mixed delivering pump inlet flow-harmonization device can make and in parallel mix each pump in the defeated pump group and move under the optimum condition that gas transmission flow and infusion flow are equal to respectively, avoids effectively crossing cause thermal damage by the pump that bias current causes.
Technological scheme of the present invention is: a kind of oil-gas multi-phase mixed delivering pump inlet flow-harmonization device comprises the liquid collecting ram's horns, have at least 2 outlets that communicate with mixed defeated pump on the liquid collecting ram's horns, outlet is the gas-liquid mixture outlet, the liquid collecting ram's horns communicates with the upper end and the lower end of the gas-liquid separation pipe that has import respectively by outlet pipe and liquid-discharging tube, corresponding liquid-discharging tube place is fixed with sieve tray in the liquid collecting ram's horns, liquid collecting ram's horns inner outlet left side is fixed with highly 1/2 weir plate for liquid collecting ram's horns diameter, the space is arranged bottom weir plate and the liquid collecting ram's horns.
The present invention has following beneficial effect: owing to take such scheme, the gas-liquid mixture that is transferred is introduced into the gas-liquid separation pipe, and the liquid of telling enters the liquid collecting ram's horns with horizontal radial from the middle part, and the gas of telling is vertically radially to enter the liquid collecting ram's horns from top.Each inlet that mixes defeated pump all is communicated with the bottom of liquid collecting ram's horns, liquid in the liquid collecting ram's horns enters and mixes before the defeated pump intake, must be introduced into liquid collecting zone, form the liquid level of certain altitude in liquid collecting zone, the bottom port of each weir plate is just to be tending towards impartial small flow to the pumping intake piping drainage; After liquid is full of liquid collecting zone, liquid overflows from each weir plate top again, directly drop down in the pumping intake piping, simultaneously, gas in the liquid collecting ram's horns also enters from the weir plate upper space and mixes defeated pumping intake piping, thereby gas, flow quantity that gas-liquid mixture is advanced before the pump are redistributed, and make in parallelly to mix each pump in the defeated pump group and move under the optimum condition that gas transmission flow and infusion flow are equal to respectively, avoid effectively crossing cause thermal damage by the pump that bias current causes.

Embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of oil-gas multi-phase mixed delivering pump inlet flow-harmonization device comprises liquid collecting ram's horns 6, have at least 2 outlets 9 that communicate with mixed defeated pump on the liquid collecting ram's horns 6, liquid collecting ram's horns 6 communicates with the upper end and the lower end of the gas-liquid separation pipe 2 that has import 1 respectively by outlet pipe 3 and liquid-discharging tube 4, corresponding liquid-discharging tube 4 places are fixed with sieve tray 5 in the liquid collecting ram's horns 6, liquid collecting ram's horns 6 inner outlets 9 left sides are fixed with weir plate 8, the quantity of weir plate 8 is identical with mixed defeated pump mounting platform number, weir plate 8 has the space with liquid collecting ram's horns 6 bottoms, the height of weir plate 8 be liquid collecting ram's horns 6 diameter 1/2.
During actual the use, gas-liquid mixture enters gas-liquid separation pipe 2 by import 1, in gas-liquid separation pipe 2, tentatively be divided into gas, liquid two-phase, gas of telling and liquid enter liquid collecting ram's horns 6 through outlet pipe 3 and liquid-discharging tube 4 respectively, liquid at first passes through the sieve tray 5 of eye with holes when entering liquid collecting ram's horns 6, the impact that feed liquor sieve tray 5 dissipates liquid to produce, liquid is steadily entered in the liquid collecting zone 7 of liquid collecting ram's horns 6, eliminate the liquid fluctuating that liquid stream is gushed and caused, and then the overflow of each weir plate 8 and vent flow are reached unanimity.Behind the liquid dissipation liquid flow impact, enter liquid collecting zone 7, after in liquid collecting zone 7, forming the certain altitude liquid level, the base apertures of each weir plate 8 begins to gas liquid outlet 9 small flow drainages, when liquid level height surpasses weir plate 8 tops, liquid is to gas liquid outlet 9 overflows, and the gas that flows through liquid collecting ram's horns 6 upper spaces flows directly into gas liquid outlet 9, enters with liquid and mixes defeated pump.The effect of described weir plate 8 has 2: the one, and no matter whether liquid level fluctuates, and all can keep the vent flow of each weir plate 8 bottom port identical; The 2nd, when slug flow appears in device portal, when causing liquid to interrupt, the liquid in the liquid collecting zone 7 can be leaked into each and mix defeated pump, keep the lubricated and cooling that mixes defeated pump.Because the height unanimity of each weir plate 8, the overflow liquid level is basicly stable, make and release the fluid flow that overflows with the top from each weir plate 8 bottoms and the gas flow that passes through from weir plate 8 upper spaces is equal to respectively, thereby, 9 the flow quantity and the steady uniform distribution of throughput have been realized respectively exporting, can make and in parallel mix each pump in the defeated pump group and under the optimum condition that gas transmission flow and infusion flow are equal to respectively, move, avoid effectively crossing cause thermal damage by the pump that bias current causes.
