Description
Technical field:
The present invention relates to a kind of multiphase booster pump, especially a kind of blade type oil gas water multiphase booster pump belongs to machine-building and multiphase flow technical field.
Background technique:
The end of the eighties, along with petroleum industry from land to the abominable relatively ocean of physical environment and the transformation in desert, turn to the exploitation of small-sized marginal field and nearby field from the larger hydrocarbon field of concentrating relatively, with the multiphase booster pump is the oil-gas multi-phase mixed transferring technology of the undressed heterogeneous well stream of remote conveying of core, obtains the extensive concern of each major oil companies with its significant technical advantage and considerable economic.But owing to the complexity of multiphase flow and the narrow limitation that we are familiar with multiphase flow, in the remote course of conveying of the heterogeneous well stream of oil gas water, traditional gas, liquid separates, by pump and compressor respectively the supercharging mode of carrying still occupy main status, in some short-range mixed transporting tube lines, gas-liquid is mixed the mode of carrying respectively after the supercharging again and is also occupied sizable ratio, the heterogeneous supercharging technology of oil gas water that is to be suitable for The field of searching to the bottom is that the development of multiphase pump itself has sizable difficulty, and the key of this technical research is to seek a kind of design method of taking into account pump and compressor performance multiphase pump.
Obtaining some preliminary achievements in research aspect the development of multiphase booster pump abroad, nearly 10 kinds of dissimilar multiphase pumps have been manufactured experimently, wherein the double-screw type multiphase mixing transmission pump produced such as the achievement in research screw axis streaming multiphase pump planned of the most representative sea God of being and German Bornemann pump industry company.The present existing part industrialization product of these two kinds of pumps, and be applied in land, offshore oilfield all over the world and the deep water oil field development.But up to the present, the performance of multiphase booster pump also can not satisfy the actual demand at scene, oil field far away, and on the one hand, because heterogeneous mobile complexity, and pump is to the dependence of fluidised form and gas content, and the using scope of multiphase pump also is subjected to certain limitation at present; Performance and the efficient of multiphase pump under high inlet gas liquor ratio operating mode all has much room for improvement on the other hand, when the spiral axial-flow pump reaches 50% when the inlet gas volume content, optimum efficiency only has an appointment 45%, and the double-screw type multiphase pump is relatively more responsive to solid particle on the one hand, volume is bigger simultaneously, surpass after 70% at the inlet gas volume content, its efficient also reduces rapidly, simultaneously multiphase pump also face anti-do change, sealing, a series of technical problem such as lubricated.With regard to the actual conditions of China, on the one hand, owing to abroad existing key technology product is holded in close confidence, on the other hand because China's oil product has high sticking, Gao Ning, contains sand, oil-gas ratio changes characteristics such as feature greatly, the external multiphase pump of introducing also occurs in using and has run into series of technical in that the oil field is on-the-spot, as the adaptability of multiphase pump convection, dried commentaries on classics, vibration, seal leakage, impurity axis etc., so the multiphase pump of the suitable China of exploitation oil field characteristic is imperative.
In China, as far back as the sixties Daqing oil field, Shengli Oil Field just once three screw rods, single screw type multiphase pump were carried out development, but big or such-and-such reasons because of technical difficulty all fails to continue further investigation.Entered since the nineties, each major oil companies of China are in line with introducing and developing the principle that combines, oil field or offshore platform carry out application study by land to introduce on the one hand external ripe equipment, unite the research work of carrying out multiphase pump with scientific research institutions on the one hand, the industrial pump factory, Tianjin, shipping industry parent company 711 waits the two screw pump of development, the Lanzhou single screw type how Ci Bengchang develops mixes defeated pump and has entered field experiment and application study stage, from present circumstances, all there is such or such problem in the multi-phase mixed delivering device of introducing and designing voluntarily in running, we can say that the technical problem of multiphase pump self existence has to a certain extent restricted the promotion and application of this technology.
The multiphase pump of domestic development is the positive displacement multiphase pump basically, with two spiral shell formula multiphase pumps is example, its typical feature is middle small flow, middle high pressure-charging, and the two screw pump multiphase pump experimental prototype that China develops at present mostly is middle low pressure charging, to the solid particle sensitivity, under equal design condition, compare its size and weight with blade mechanism all bigger; For traditional vane pump, because action of centrifugal force during high speed rotating, make that having liquids and gases of different nature is easy to take place the phase separation, thereby cause the efficient of pump under the gas-liquid two-phase flow condition sharply to reduce even can not work, conventional centrifugal pump is when the inlet gas volume content reaches 4%, its efficient just reduces rapidly, can't turn round basically when the inlet gas volume content surpasses 10%; Axial-flow pump surpasses after 20% at inlet gas content substantially, and efficient sharply reduces up to losing boosting capability.

As shown in Figure 1, the end of supercharging device 3 is provided with final stage diffuser 33 and delivery chamber, is used to realize that heterogeneous fluid kinetic energy is to the pressure conversion of energy.The radial design of final stage diffuser 33 for optimizing, delivery chamber can adopt annular delivery chamber, guarantees the further conversion of kinetic energy on the one hand, also can make on the other hand to have the further exchange energy of energy between the relative speed difference gas-liquid two-phase, reduces speed sliding difference.
As can be known from Fig. 1, blade type oil gas water multiphase booster pump also comprises bearing, sealing, auxiliary device such as lubricated except above-mentioned main device.The pump housing of suction booster adopts segment design, is convenient to installation and removal, and the hole of regularly removing sand is arranged in the chopped-off head pump housing; Final stage at pump is equipped with cooling jacket, is used to ensure that pump is in the service behaviour of doing under the running operating mode.
Compressibility according to gas, the front and back grade blade adopts different design parameters, before what design focus on avoid the phase between the gas-liquid to separate, so choosing with choosing of supercharging value of head coefficient is all more conservative, what design focal point of back is placed on and mixes in the supercharging, and design supercharging value is bigger.
In addition, vertical structure is adopted in the design of multiphase pump unit, motor on top, the pump housing is in the bottom, the rotating speed of pump adopts variable-frequency governor, the import and export of pump have pressure, temperature, flow testing device, carry out rotational speed regulation foundation is provided for frequency variator changes according to the incoming flow situation.
