Abstract
The invention provides a rotational flow booster for a turbine flow meter in order to solve the problems that the traditional turbine flow meter is unlikely to start when the flow is low and the resolution cannot meet measuring demands. The rotational flow booster is characterized in that a lower center hole (3) is arranged in the centre axis direction of a main body (1); and the external surface of the main body (1) is provided with a spiral blade (2) with the spiral angle of 135 DEG. With the adoption of the rotational flow booster for the turbine flow meter, the starting output volume of the turbine flow meter can be greatly reduced and the resolution can be improved, so that the demand for low-permeability oil field development is met.
Description
Technical field
The present invention relates to the oil reservoir logging field, the eddy flow booster that especially a kind of turbine flowmeter is used.
Background technology
Liquid producing profile log is the important supporting technology of oil field development, and the liquid producing profile log data is the important evidence that oilfield development program is formulated and adjusted.At present, turbine flowmeter remains the main method of flow measurement in the oil well liquid-producing profile logging, and along with the exploitation of low permeability oil field, full well production is lower than 5m
3/ d, individual layer output is lower than 1 m
3The oil well quantity of/d increases year by year.Existing turbine flowmeter arrival end is straight length and axial diversion sheet, flow fluid before flow meter only has axial velocity, fluid is that fluid is to the moment of torsion of the radial component generation of turbine active force to the driving force of turbine, therefore, existing turbine flowmeter is lower than 1 m connecting in the umbrella formula current collector situation at flow
3During/d, the situation that turbine can not start often occurs, resolution ratio can not satisfy the measurement requirement, causes the decline of success log ratio.Solve turbine flowmeter flow measurement Lower Boundary, further reduction startup discharge capacity is significant and value to the dynamic monitoring of oil field development.
Summary of the invention
Existing turbine flowmeter turbine when flow is low can not start in order to overcome, resolution ratio can not satisfy the deficiency of measuring requirement, the invention provides the eddy flow booster that a kind of turbine flowmeter is used, the eddy flow booster that adopts this turbine flowmeter to use, can greatly reduce the startup discharge capacity of turbine flowmeter, improve resolution ratio, thereby satisfy the needs of LOW PERMEABILITY OILFIELD DEVELOPMENT.
Technical scheme of the present invention is: the eddy flow booster that a kind of turbine flowmeter is used, comprise main body, and described main center axis direction is provided with lower center hole, and the main body external surface is provided with spiral blade, and the helical angle of blade is 135o.
The present invention has following beneficial effect: owing to take such scheme, the blade screw angle of this eddy flow booster is 135o, by the spiral-flow type booster being installed in the arrival end of turbine flowmeter, flow fluid when booster produces and rotatablely moves, so that fluid has increased rotatablely moving radially on the constant basis of axial flow velocity, increase the driving force of fluid to turbine, realized reducing the purpose that starts discharge capacity and improve resolution ratio.And this apparatus structure is simple and reliable, need not change former logger structure, is easy to realize sizable application.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, the eddy flow booster that a kind of turbine flowmeter is used comprises main body 1, described main body 1 central axial direction is provided with lower center hole 3, main body 1 external surface is provided with spiral blade 2, and the helical angle of blade 2 is 135o, the angle quadrature of this angle and turbo blade.Fig. 2 is the structural representation that installs the turbine flowmeter of eddy flow booster additional, the two ends of inner core assembly 10 are fixed with respectively top 11 and lower top 8, the left end cylinder of turbo blade 7 is inlaid with magnet steel 7 outward, the left side upper top 11 on be fixed with Hall element frame 5, be pasted with Hall element 6 on the Hall element frame 5, and fixing by turbine and tight cap 4.The eddy flow booster is connected to lower top 8 outsides of right-hand member, and its outside welds together assurance and turbo blade 7 axialities with inner core assembly 10.
Spiral-flow type booster of the present invention is installed in the arrival end of turbine flowmeter, flow fluid when booster produces and rotatablely moves, so that fluid has increased rotatablely moving radially on the constant basis of axial flow velocity, the direction of rotation of fluid is consistent with the rotation direction of turbine, under the same traffic condition, increase the driving force of fluid to turbine, realized reducing the purpose that starts discharge capacity and improve resolution ratio.This device has simple and reliable for structure, need not change the characteristics of former logger structure, is easy to realize sizable application.Be mainly used in the low permeability oil field flow measurement, reduce the startup discharge capacity of turbine flowmeter and the resolution ratio of raising turbine flowmeter, thereby satisfy the needs of LOW PERMEABILITY OILFIELD DEVELOPMENT.
