Description
The utility model relates to a kind of loose-leaf system flowmeter, and it belongs to the device of measuring injection and production profile in the petroleum industry production logging field.
In the intermediary and later stages of waterflooding oil field, the accurate measurement of injection and production profile is fallen end cost of winning by oilfield development program to rationally determining, improves field output and is significant.Now waterflooding oil field all over the world enters the intermediary and later stages mostly, inject and production profile logging become one significant, expend huge fund and essential activity in production.At present, the method that is used for injection profile logging mainly contains radioactivity microballoon method and two kinds of methods of turbo flow meter, and in production profile logging, mainly depends on a kind of method of turbo flow meter.These two kinds of logging methods all have very big scarce limit, though wherein turbo flow meter all can use in injection and production profile logging, influence factor is many, and dynamic range is little, and when particularly using in containing gas well, measurement result is especially unreliable; Though radioactivity microballoon method does not have above-mentioned shortcoming, but can only be used for input profile measures, and construction is complicated, need formulate concrete arrangement and method for construction at each mouthful well, more trouble is, because the selected radioactive source half life period is short,, so not only increased cost widely so need to prepare microballoon frequently, termly, and, be difficult to carry out large-scale logging technology service for extremely unfavorable away from the base operation.Yet for these two kinds of logging methods, maximum, also be that common difficulty is exactly annotating high viscosity fluid, in polymer injection well, be difficult to accurately measurement.
The purpose of this utility model is to provide a kind of variation that the variation of in-hole fluid flow can be converted to the loose-leaf subtended angle, and then convert the well logging apparatus one loose-leaf system flowmeter of the resistance change that can measure by cable to, it can be measured accurately, quickly and easily and inject and production profile, and can use in complicated well.
The purpose of this utility model is realized by following technical scheme: it is by mozzle (1), loose-leaf (2), postive stop baffle (3), guide roller (4), tension spring (5), precision resistor (6) is formed, loose-leaf (2) is installed in the interior middle position of mozzle (1), rotating shaft (8) is fixed on loose-leaf (2) the one end limits, guide roller (4) is packed in the rotating shaft (8), postive stop baffle (3) is packed on mozzle (1) inwall, be positioned at loose-leaf (2) upper end, packing washer (7) is packed in below the postive stop baffle (3), a bearing (9) respectively is equipped with at rotating shaft (8) two ends, and bearing (9) is packed on mozzle (1) inwall; Backguy (10) one ends are fixed on the guide roller (4), its other end is fixed on the mobile terminal of tension spring (5), the stiff end of tension spring (5) is packed in to be adjusted on the screw (13), adjusting screw (13) is installed in the line of rabbet joint of mozzle (1) wall, can move up and down, the slide head of precision resistor (6) is fixed in the backguy (10), mozzle (1) both ends open, inlet (11) is driveed in the upper surface, and leakage fluid dram (12) is driveed in the lower surface.Guide roller (4) is an elliptic wheel, and there is a groove centre, and backguy (10) is stuck in the groove; Bearing (9) adopts the blade-like carrying plane, and rotating shaft (8) corresponding site adopts triangular shaped recess surface; Precision resistor (6) two termination cables, and link by cable and voltage table, constant current source.
The utility model has the advantages that and adopted loose-leaf structure, the various factors that influence accuracy in traditional flow measurement are reduced to minimum, be applicable to measure and inject and production profile, in the polymer injection well of simple water injection well and complexity, can both use, applied widely.Novel structure of the present invention, simple, easy to use, cost is low, is convenient to promote the use of.
