Description

A kind of compact GLCC separates supercharging device
Technical field
The utility model relates to a kind of compact GLCC and separates supercharging device.
Background technology
" 2000 meters of depth of waters compact eliminator key technology and model machine under water " is one of problem of National 863 major project " deep water hydrocarbon resources exploration technology and equipment ".The problem task that Ningbo Veritas-msi Multiphase Flow Equipment Co., Ltd bears is: a set of 2000 meters of deep-seas compact separation-pressurization system engineering prototype under water that is applicable to is manufactured in exploitation.
Deep-sea oil production technique scheme mainly at present: the gas-liquid mixture that offshore mining goes out is transported to offshore platform or oil gas treating stations by lift pump device together, and then carry out gas-liquid separation processing, the shortcoming of such technical scheme is: when (1) raising mixed gas and liquid is carried, in pipeline, there will be one section of gas, one section of liquid, it is slug flow, when segment occurred plug flow, gas and liquid alternated mobile in pipeline, the liquid plug that is full of whole pipeline area can be cut apart by air mass, and along Flows below air mass is interface film.In the time presenting slug flow in pipeline, the pressure of pipeline, the instantaneous delivery of gas-liquid have very large fluctuation, can cause pressure-drop in pipeline sharply to increase, very large to the anxious pipeline impact of equipment, easily cause equipment and Pipeline damage.(2) lift pump device volume is large, and be difficult to lifting in seabed and install, installation and maintenance somewhat expensive, and also consumed power is large, carries electric equipment and cable to have higher requirements to seabed, and Meteorological is large.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and completes gas-liquid separation in seabed, gas after separation, liquid output to respectively offshore platform or oil gas treating stations, can not produce slug flow, simple and compact structure, a kind of compact GLCC that cost is low separates supercharging device.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of compact GLCC separates supercharging device, comprise GLCC cyclone separator, described GLCC cyclone separator comprises cut sth. askew pipe and vertical tube, the described pipe of cutting sth. askew is tangentially fixed on described vertical tube, the upper end of described vertical tube is provided with gas vent and its lower end is provided with liquid outlet, also comprise a vertical pressurized surge vessel, described gas vent is communicated with the top of described pressurized surge vessel, described liquid outlet is communicated with the bottom of described pressurized surge vessel, the upper end open of described pressurized surge vessel is provided with wellhead assembly, the lower end sealing of described pressurized surge vessel arranges, the inside of described pressurized surge vessel is provided with the electric submersible pump for supercharging.
Between described gas vent and described pressurized surge vessel, be connected by pipeline welding or flange connection, between described liquid outlet and described pressurized surge vessel, be connected by pipeline welding or flange connection.
The horizontal projection distance that described vertical tube and described pressurized surge vessel horizontal line between the two and the described pipe of cutting sth. askew are horizontal range between the two of 60 ° and described vertical tube and described pressurized surge vessel and the described pipe of cutting sth. askew on horizontal plane is identical.Vertical tube, cut sth. askew pipe and pressurized surge vessel three on horizontal plane, be equilateral triangle distribute, there is good stability.
The center line of the described pipe of cutting sth. askew and described vertical tube are 63 °.Described gas-liquid mixture enters vertical tube by tangential inlet, has better centrifugal force under this angle, and gas-liquid separation effect is better.
The entrance of the described pipe of cutting sth. askew is provided with feed pipe, and the bottom of described feed pipe, described vertical tube and described pressurized surge vessel is provided with bearing.
Compared with prior art, the utility model has the advantage of: the utility model discloses first a kind of compact GLCC and separated supercharging device and manufacture method thereof, two of this device employing GLCC cyclone separator and pressurized surge vessels, pressurized surge vessel main body is a vertical vessel that can bear interior external pressure, wellhead assembly is equipped with in its upper end, lower end closed, electric submersible pump is equipped with in inside, realizes function of increasing pressure.Gas-liquid separation completes separation in GLCC cyclone separator, the liquid phase separating enters into pressurized surge vessel bottom from the liquid outlet of vertical tube, the gas phase separating enters into pressurized surge vessel top from the gas vent of vertical tube, gas after separation, liquid output to respectively offshore platform or oil gas treating stations, and its advantage is as follows:
1, simple in structure, formed by GLCC eliminator and pressurized surge vessel, easily manufacture, need not keep in repair throughout the year;
2, compact conformation, floor space is little, has realized two functions of separation and supercharging simultaneously;
3, this structure vertical tube, cut sth. askew pipe and pressurized surge vessel three on horizontal plane, be equilateral triangle distribute, there is good stability;
4, complete gas-liquid separation in seabed, the gas after separation, liquid output to respectively offshore platform or oil gas treating stations, because gas separates with liquid, and can not carry as gas-liquid mixture time, one section of gas in pipeline, one section of liquid, avoids the generation of slug flow phenomenon;
5, capital cost is less than traditional lift pump device, because gas-liquid is separated, reliable self the pressure of gas can upwards flow, as long as adopt lift pump device to promote to liquid, due to reducing of conveying capacity, lifting appliance unit type also reduces, manufacturing expenses, seabed lifting and mounting cost also reduce, and total investment cost is more many than prior device small investment.
