Technical field
The utility model relates to a kind of oil and gas multiphase flow sledge, is a kind of skid-mounted oil-gas mixing conveying system, belongs to crude oil transmission field.
Background technique
The rock gas be extracted together with the also adjoint oil of oil symbiosis between oil reservoir, is called as associated gas.For a long time, be subject to the restriction of the factor such as technological means, financial cost, the associated gas in most of oil field is all drained or has burnt.This is waste the one of resource, also can cause the destruction to environment simultaneously.In order to improve transfer efficiency, conventional method is first separated by liquid phase, then respectively with carrying the pump of liquid and carrying the compressor of gas to liquid and gas pressurized delivered, this just needs a whole set of separation equipment and two to overlap independently gas, liquid transfer line, and required equipment, place are invested larger.And oil-gas mixing conveying system replaces common liq transfer pump and compressor with a multiphase mixing transmission pump; eliminate numerous and diverse separation equipment and conveyance conduit; both capital investment was decreased; protect environment again, because of but be applicable to the development scheme of a kind of high-efficiency and economic of marine oil field, marginal oil field, Desert Oilfields and nearby field.Traditional oil-gas mixing conveying system utilizes double-screw mixing transmission pump to carry out pressurized delivered to destination to oil gas.But this pump displacement is little, responsive to silt, and screw rod outer rim and the cylinder body pressure afterwards that weares and teares reduces rapidly, cause that pump work reliability is low, amount of maintenance is large, the life-span is low, operating cost is high, especially when high gas-liquid ratio is carried, mixing pump efficiency can be had a greatly reduced quality.Therefore, in actual application, be badly in need of improving existing oil-gas mixing conveying system.
Summary of the invention
The purpose of this utility model is the deficiency existed to solve prior art, provides a kind of oil and gas multiphase flow sledge, can realize carrying the oil gas of high gas-liquid ratio; Treating capacity is large, and efficiency is high, and sledge assembling structure is compact, floor space is little, movement is easy for installation.
The technological scheme that the utility model adopts is:
A kind of oil and gas multiphase flow sledge of the utility model, primarily of cyclone separator, compressor, centrifugal pump, control cabinet, gas buffer tank, fluid cushion tank, pressure transducer, flow transducer, temperature transducer, throttle valve, safety check, gate valve, sledge composition, described cyclone separator is positioned at the left side of sledge, compressor is arranged in the top of sledge, centrifugal pump is arranged in the below of sledge, and control cabinet is arranged in the top of sledge; The pipeline that oil gas header is connected with cyclone separator is provided with throttle valve; The liquid input tube line that the gas inlet pipe line that cyclone separator is connected with compressor is connected with centrifugal pump with cyclone separator is connected to gas buffer tank, fluid cushion tank, pressure transducer, flow transducer, temperature transducer; The gas output tube line of compressor and the liquid export line of centrifugal pump are separately installed with safety check and gate valve, and gas output tube line and liquid export line finally synthesize an oil and gas multiphase flow pipeline; Described compressor, centrifugal pump, pressure transducer, flow transducer, temperature transducer link together with control cabinet respectively.
When mixed oil and gas enters cyclone separator from outside through oil gas header, regulate throttle valve can control the flow entering cyclone separator, mixed oil and gas is after cyclone separator is separated, flow out through safety check and gate valve after rock gas enters compressor pressurizes speedup, crude oil flows out through check valve and gate valve after entering centrifugal pump pressurization speedup, jointly enter oil and gas multiphase flow pipeline after the rock gas flowed out and crude oil finally fully mix with higher pressure and speed, be passed to central treating station by mixed.Pressure signal, flux signal, temperature signal are communicated to control cabinet by the pressure transducer on input output pipeline, flow transducer, temperature transducer respectively, control cabinet judges signal according to these signals, and signal is conveyed to respectively the frequency variator of compressor and centrifugal pump, thus change the rotating speed of motor, make the change of the flow of compressor and centrifugal pump adaptation fluid, pressure and temperature, improve the working efficiency of compressor and centrifugal pump.
Compared with prior art, the utility model has the advantage of:
1, use oil and gas multiphase flow sledge to eliminate numerous and diverse separation equipment and conveyance conduit, both decreased capital investment, and protected environment again, because of but be applicable to the development scheme of a kind of high-efficiency and economic of marine oil field, marginal oil field, Desert Oilfields and nearby field; 2, be separated by oil gas with cyclone separator, the silt in oil gas can be removed, treating capacity is large, good separating effect; 3, mixed defeated after carrying out the process of pressurization speedup to rock gas and crude oil respectively with compressor and centrifugal pump, can carry the oil gas of high gas-liquid ratio, not only treating capacity is large, and oil and gas multiphase flow efficiency is high, compressor and the centrifugal pump life-span long; 4, control cabinet controls the motor speed of compressor and centrifugal pump by the pressure signal on Gather and input export pipeline, flux signal, temperature signal, makes compressor and centrifugal pump adapt to the changes in flow rate of fluid, improves the working efficiency of compressor and centrifugal pump; 5, sledge assembling structure is compact, floor space is little, movement is easy for installation.Have structure simply novel, reliable performance, the life-span is long, strong adaptability.
