Abstract
The invention discloses a jet type crude oil and associated gas pressurization mixed transportation process and a device, which are designed for effectively solving the problems of oil-gas mixed transportation and recovery and utilization of available natural gas, namely, the coming oil is filtered by a filter and then is input into a buffer tank to separate the associated gas in the coming oil; inputting the separated associated gas into a separation tank, and inputting the separated crude oil into a mixing transmission pump for pressurization; and finally pumping the separated associated gas into a jet pump, mixing the associated gas with the pressurized crude oil, and outputting the mixed gas. The invention can stabilize the components of the crude oil pressurized by the mixing transportation pump and has low oil-gas content ratio. The jet pump pumps the associated gas to realize oil-gas mixed transportation, can eliminate the bad influences of vibration, heating and the like caused by the fact that the oil gas is directly mixed transported by the pump, prolongs the service cycle of the pump and reduces the maintenance cost. The jet pump has simple mixed conveying structure, no moving parts and good mixed conveying effect. The process improves the operation efficiency of the system, recycles all associated gas in the crude oil, and improves the resource utilization rate.
Description
Technical field
The present invention relates to a kind of jet-type crude oil and associated gas supercharging mixed transportation process and device, belong to oil gas field oil, gas conveying technology field.
Background technique
Contain associated gas in the crude oil, according to existing technology, supercharging point and multi-purpose station only to crude oil heat, supercharging and outer defeated, oil gas is not handled.Existing website oil and gas multiphase flow technology mainly contains following two kinds: first kind of oil gas small part separating technology, namely oil through separation buffer jar cutting out partial associated gas, uses back and all the other to come oil directly through mix defeated pump outward defeated for oven according to on-the-spot technology.Under this technology, come oily medium composition extremely unstable, as it is low when higher than the time to contain big strand of slug flow or hydrocarbon content, can be greater than mixing the requirement of defeated pump to medium hydrocarbon content ratio in the time of high, and then cause pump under extremely unstable and abominable operating mode, to work, cause pipeline to meet with impact shock.And, pump heating easy break-down, the working efficiency that shortened the working life of pump, the maintenance cost raising reaches mixed communication system reduces.Second kind of most of separating technology of oil gas namely to all coming oil to carry out Oil-gas Separation through the separation buffer jar, like this, comes the most of associated gas in the oil to separate, and wherein a part is used for oven.Mixing the outer defeated crude oil of defeated pump is the stable after separating in the knock out drum, does not contain big strand of slug flow, and the hydrocarbon content ratio is stable and lower, can make the operating mode of pump good like this, and system is stable, and efficient is higher.But problem is isolated associated gas oven can only use a small part, and all the other associated gases then can't be handled, and it is uneconomical to lay gas pipeline in addition, so adopt the processing mode of on-the-spot emptying or torch burning, causes environmental pollution and the wasting of resources.
Summary of the invention
The object of the present invention is to provide a kind of jet-type crude oil and associated gas supercharging mixed transportation process and device, its can solve effectively available rock gas recovery, carry and utilize problem.
Jet-type crude oil of the present invention and associated gas supercharging mixed transportation process step are as follows:
(1). in the future oil filter through filter and oven heating back input buffering jar (perhaps according to operating mode, in the future oil without heating direct input buffering jar), separate to come the associated gas in the oil;
(2). with isolated associated gas input associated gas knockout drum, isolated crude oil input is mixed defeated pump supercharging;
(3). isolated associated gas suction Jet injector is mixed with crude oil after the supercharging, after heating outside defeated (perhaps according to operating mode, that the mixed oil gas after the supercharging is directly outer defeated without heating).
The technology contents of the mixed conveying device of jet-type crude oil of the present invention and associated gas supercharging is as follows:
Filter connects knock out drum through pipeline, and the pipeline through being communicated with oven connects knock out drum simultaneously.Knock out drum connects the associated gas knockout drum through pipeline, connects through pipeline simultaneously and mixes defeated pump, mixes defeated pump and connects Jet injector.The associated gas knockout drum connects Jet injector through pipeline, connects oven through pipeline simultaneously.Jet injector connects the oil gas external transport pipeline through pipeline, and the pipeline through being communicated with oven connects the oil gas external transport pipeline simultaneously.
The present invention adopts the most of method of separating of accompanying gas with crude oil, makes through mixing the conveying crude oil stable components of defeated pump supercharging, and hydrocarbon content is than low.Jet injector suction associated gas is realized oil and gas multiphase flow, can eliminate because of oil gas and directly mix baneful influences such as the defeated vibrations that cause and heating, the life cycle of prolongation pump, reduction maintenance cost through pump.Jet injector mixes defeated simple in structure, movement-less part, and basic fault-free except wearing and tearing is mixed defeated effective.The present invention can improve running efficiency of system, and the associated gas in the crude oil is all recycled, and improves resource utilization.
Description of drawings
Accompanying drawing is that jet-type crude oil and associated gas supercharging mix the conveying device structural representation.
Embodiment
Embodiment:
With reference to accompanying drawing embodiments of the invention are further specified:
Jet-type crude oil and associated gas supercharging mixed transportation process step are as follows:
(1). in the future oil filter through filter 1 and oven 5 heating back input buffering jars 6 (or according to operating mode, in the future oil without heating direct input buffering jar 6), separate to come the associated gas in the oil;
(2). with isolated associated gas input associated gas knockout drum 7, isolated crude oil input is mixed defeated pump 2 and 3 superchargings;
(3). isolated most of associated gas suction Jet injector 4 is mixed with crude oil after the supercharging, defeated outside after heating (or according to operating mode, the mixed oil and gas after the supercharging is directly outer defeated without heating).
The technology contents of the mixed conveying device of jet-type crude oil and associated gas supercharging is as follows:
Filter 1 connects knock out drum 6 through pipeline, and the line b through being communicated with oven 5 connects knock out drum 6 simultaneously.Knock out drum 6 connects through pipeline f simultaneously and mixes defeated pump 2 and mix defeated pump 3 through pipeline connection associated gas knockout drum 7, mixes defeated pump 2 and is connected Jet injector 4 simultaneously with mixed defeated pump 3.Associated gas knockout drum 7 connects Jet injector 4 through pipeline g, connects oven 5 through pipeline e simultaneously.Jet injector 4 connects oil gas external transport pipeline d through line c, and the pipeline through being communicated with oven 5 connects oil gas external transport pipeline d simultaneously.
