Abstract
The utility model relates to a multiphase mixed transport pump for oil, gas and water, comprising an inflow cone, a conical spiral rotary wheel, a rectifier and an eduction casing, wherein the inflow cone, the conical spiral rotary wheel, the rectifier and the eduction casing are coaxially arranged inside a pump casing. The conical spiral rotary wheel is a conical cylinder shape, the outer wall of the cone is provided with a spiral blade. The rectifier and the pump casing are relatively fixed, wherein the rectifier is a column sleeve shape, a blade with axial flow is arranged between an inner sleeve and an outer sleeve. The mixed transport pump designed by the utility model gives consideration to two phase flows of gas and liquid, and is applicable to the operation under high speed. As the variable-speed operation can adapt the variation of the underground stratum flow pattern of gas and liquid, the utility model can carry trace solid oil sand in the oil, gas and water, prevent blocking in the channel, and reduce abrasion, can reduce the cost of pipe laying and operation; meanwhile, the wellhead pressure of the oil well can be reduced for improving the fluid withdrawal rate.
Description
Technical field
The utility model relates to a kind of oil gas water multiphase mixing transmission pump, and the supercharging that is used under oil gas water and a small amount of heterogeneous admixture of sand is mixed defeated, belongs to the Fluid Machinery and Engineering equipment technical field.
Background technique
The multiphase pump that oil fields such as triumph at present, ocean are used is the twin-screw type, belongs to positive displacement, its structure as shown in Figure 1,1 is screw rod among the figure, the working principle of this multiphase pump is to lean on the engagement extrusion fluid between the screw rod to reach supercharging.Its deficiency mainly is that the pump core weares and teares easily when containing the solid sand grains in the oil gas, and simultaneously the physical dimension of the pump housing is bigger than normal, and is huger during especially big flow.
Summary of the invention
The purpose of this utility model is a kind of oil gas water multiphase mixing transmission pump of design, changes the structure of prior art, and with big flow in being suitable for, the heterogeneous supercharging of the oil, gas, water and sand of mesolow power mixes defeated.
The oil gas water multiphase mixing transmission pump of the utility model design includes flow cone, coniform spiral runner, rectifier and derivation shell.Go into flow cone, coniform spiral runner, rectifier and the derivation shell is coaxial is installed in the pump case.The coniform spiral runner is a taper barrel, and the cone outer wall is provided with spiral vane; Described rectifier and pump case relative fixed, rectifier is a cylindrical sleeve, is provided with the blade of axial flow between the inner and outer sleeves.
The heterogeneous supercharging of oil gas water of the utility model design mixes defeated pump, has following characteristics and purposes:
(1) the heterogeneous supercharging flow design of mixing defeated pump had not only designed not according to pure liquid but also not according to pure gas, was to take into account the gas-liquid two-phase flow specialized designs.Foreign steamer external diameter and progression require according to the flow of oil gas water and supercharging and decide.
(2) running speed can be particluarly suitable for operation down at a high speed in constant speed and speed change from 3000 rev/mins to 6000 rev/mins.Because variable-speed operation can adapt to the variation of oil gas down-hole formation fluidised form.
(3) be open architecture in the design's member, between the supercharging element, be not in contact with one another, can in oil gas water, carry micro-solid oil-sand, in runner, be unlikely obstruction, reduce wear.
(4) uniform pitch or variable pitch, distortion is chosen by different oil-gas ratio optimizations with the blade profile of non-distortion.
(5) complete machine can be divided into plurality of sections among the design, and it is same size that the impeller of each section is led rectifier, and the size of subsequent segment is little than leading portion, can choose according to the supercharging height.
(6) the design is defeated owing to mixing, and can reduce tubing and operating cost.Can reduce simultaneously the well head pressure of oil well, help improving and adopt liquid measure.
Description of drawings
Fig. 1 is the structural representation of the twin-screw multiphase pump of prior art.
Fig. 2 is the oil-gas multi-phase mixed delivering pump structure schematic representation of the utility model design.
Among Fig. 1 and Fig. 2, the 1st, screw rod, the 2nd, go into flow cone, the 3rd, the coniform spiral runner, the 4th, rectifier, the 5th, derive shell, the 6th, the axle envelope, the 7th, bearing, the 8th, pump case, the 9th, the spiral vane of coniform spiral runner outer wall, the 10th, the inner sleeve of rectifier, the 11st, the outer sleeve of rectifier, the 12nd, the blade of the axial flow between the inner and outer sleeves.
Embodiment
As shown in Figure 1, the oil gas water multiphase mixing transmission pump of the utility model design includes flow cone 2, coniform spiral runner 3, rectifier 4 and derives shell 5.Go into flow cone 2, coniform spiral runner 3, rectifier 4 and derive shell 5 coaxial being installed in the pump case 8.Coniform spiral runner 3 is a taper barrel, and the cone outer wall is provided with spiral vane 9.Rectifier 4 and pump case 8 relative fixed, rectifier 4 is a cylindrical sleeve, is provided with the blade 12 of axial flow between the inner and outer sleeves 10 and 11.Its working principle is that fluid forces motion vertically in the coniform spiral impeller, prevents that effectively gas-liquid two-phase from separating in runner, and fluid is converted into pressure energy with the kinetic energy of fluid again in rectifier.Thereby make fluid in each cell level, all increase energy.
In the above-mentioned oil gas water multiphase mixing transmission pump, each impeller and rectifier are formed a unit, and complete machine can be multistage the composition by a plurality of unit.
Importing awl can revolve needs and be carved with spiral chute according to giving.The blade profile of rotary blade has the feature of spiral and axial flow concurrently, its semi-cone angle, laying angle, wheel hub when the number of blade be particular design with the heterogeneous mobile kinetic energy of supercharging, its pitch branch has two kinds of uniform pitch and variable pitchs.The blade profile of rectifier is regardless of under prerequisite in the heterogeneous fluidised form of assurance kinetic energy is converted to the pressure energy, and its blade divides two kinds of distortion and non-distortions.Design parameter is chosen according to the oil-gas ratio difference.
