Domain.
Background technology
The Unconventional gas such as coal bed gas, shale gas, utilization can generate huge economic benefit, also help
Safety and environmental protection, but also there is certain bottleneck problem.Currently, China's major part coal bed gas gas output per well is smaller, and
Shale gas gas well tolerance is larger but decaying is very fast.According to statistics, hundreds of mouths, thousands of mouthfuls of well scales block, daily average production per well
Less than 800 cubic metres, even lower than 500 cubic metres.Some block gas well initial productions are higher, but in 1-3, individual well is average
The daily output drops to only several hectosteres.Since rapid decay block and low yield block are in the unconventional day of development phase
Can accounting be big in right gas block, rationally utilize the pressure energy of different gas wells itself to realize that the efficiently collection of Unconventional gas is defeated,
It is the critical issue for restricting the industry.
Traditional injector belongs to velocity profile injection, and sub-thread high-pressure spray is realized by the low feature of swiftly flowing Fluid pressure
Body aspirates the purpose of sub-thread low-pressure fluid, and applicable working condition range is smaller, needs the actual condition design for different well heads corresponding
Injector, undoubtedly increase cost of winning for this Unconventional gas small to well yield, cannot be satisfied low cost and open
The demand of hair.The Unconventional gas of multiple low pressure well heads is carried out collecting defeated using separate unit injector, due to different low-pressure gas wells
Between pressure there are larger difference, can only be directed to the design that the minimum well head of pressure rating carries out collector and delivery pipe road, remaining gas well by
It is higher than collector and delivery pipe road pressure rating in pressure, it is larger in energy loss caused by entrance, it cannot achieve and efficiently collect defeated.Therefore, it passes
System injector is restricted in the defeated field scale use of the Unconventional gas collection such as coal bed gas and shale gas.
The strong vortex lead jetting device patent of dynamic of Patent No. 2015102865890 proposes that the low pressure formed by eddy flow is real
Now aspirate the function of sub-thread low-pressure gas.The circumferential weld injector patent of Patent No. 201710278955.7, by circular high
The vacuum environment that fast air-flow is formed realizes the function of suction sub-thread low-pressure gas.The core of these induction apparatus is all to utilize sub-thread
High-pressure fluid injection sub-thread low-pressure fluid can not consider that different pressures grade collects the reasonable utilization of gas transmission body pressure itself energy, make
At certain energy loss.Although can solve the problems, such as this by multiple induction apparatus of connecting, in equipment and pipeline complexity, cost
It rises, the low cost that cannot meet Unconventional gas collects defeated needs, therefore, researches and develops sub-thread high-pressure fluid injection multiply lowpressure stream
The multi-functional induction apparatus of body has preferable application value.
Invention content
A kind of multifunctional static induction apparatus of the present invention is retaining ejection function of the traditional static injector to single flow
Under the premise of, the method that the low-pressure fluid different to pressure rating uses pressure classification makes the low-pressure fluid of different pressures pass through
The collector and delivery pipe road of its corresponding pressure rating enters equipment, since pressure itself is higher than when avoidable low-pressure fluid flows through collector and delivery pipe road
The pressure loss of energy caused by loine pressure grade improves the defeated efficiency of collection of Unconventional gas, reduce the exploitation of induction apparatus at
This.The different low-pressure fluid of multiply pressure rating is by one high-pressure fluid or the axial high speed of itself and the fluid-mixing of low-pressure fluid
The low-pressure area inhalation device of flowing and high-speed rotational formation simultaneously carries out energy exchange, realizes sub-thread high-pressure fluid injection multiply low pressure
The function of fluid.The multifunctional static induction apparatus single device can realize the function of more traditional injector parallel connections, avoid
Pipeline complex process, cost of equipment during a variety of pressure rating gas injections is high, the problems such as taking up a large area, has preferable
Application value.
In addition, when the device only opens one of low pressure inlet, it is just equivalent to traditional injector single flow injection
The scheme of single flow, has the function of a tractor serves several purposes.
The technical solution adopted by the present invention is：A kind of multifunctional static induction apparatus, it includes tail portion contraction section, throat's pipe
