Abstract
A horizontal well liquid production profile tester is applied to monitoring the liquid output condition of a horizontal section in the production process of an oil field horizontal well. The lower end of the magnetic positioning short circuit is connected with a test pipe column, the upper end of the test pipe column is fixed with an upper centralizer, the lower end of the test pipe column is fixed with a lower centralizer, and a circuit board, a moisture content meter, a flow meter and a current collector are sequentially fixed in the test pipe column from top to bottom. Liquid outlet holes are uniformly distributed on the pipe wall at the upper part of the moisture content meter. The effect is as follows: the coaxial transmission line is used as a sensor, so that the sensor has the characteristics of interference resistance, small signal attenuation, reliable work and good application effect. The method is suitable for testing the liquid production section of the horizontal well with medium and low yield.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and the downhole instrument of monitoring horizontal segment fluid situation is a horizontal well producing profile testing instrument in particularly a kind of horizontal well manufacturing process.
Background technology
In the oilfield horizontal well oil recovery process, provide basic data for optimizing injection-production program and meticulous pool description, instruct pressure break, water-blocking operation and estimate pressure break, water-blocking operation effect, need test, provide horizontal well whether to have Shuitu to advance key messages such as the position of advancing by leaps and bounds with water production profile.Along with horizontal well is used the rapid expansion of scale and the prolongation of time, the liquid producing profile log data manifests day by day to the effect of the efficient exploitation of horizontal well, realizes that for the oil field sustainable development has great importance.
Compare with peupendicular hole, the difficult problem of horizontal well liquid producing profile log is to need solution that logger is transported to horizontal well and treat the well logging section, and measure flow and every component under the complicated multinomial stream flow regime.Existing tractor can only be applied to the horizontal well liquid producing profile log of high yield blowing.For in the majority, the low yield oil well, existing tester incompatibility can't be measured oil well liquid-producing flow and moisture content exactly.
The utility model content
The purpose of this utility model is: provide a kind of horizontal well producing profile testing instrument, in being applicable to, low yield horizontal well producing profile testing.
The technical solution adopted in the utility model is: horizontal well producing profile testing instrument, mainly form by magnetic orientation short circuit, last centralizer, circuit board, moisture content meter, flow meter, current collector and following centralizer, lower end at the magnetic orientation short circuit is connected with test string, be fixed with centralizer in the test string upper end, fixing centralizer down is characterized in that: be fixed with circuit board, moisture content meter, flow meter and current collector from top to bottom successively in test string in the test string lower end.On the tube wall on moisture content meter top, be evenly distributed with fluid hole.
What described moisture content meter adopted is coaxial line phase method moisture content meter.Its operating principle of coaxial line phase method moisture content meter is: utilize coaxial line to make sensor, production fluid during oil well production is through flowing through between the inner wire of coaxial line sensor and outer conductor behind the current collector afflux, and become the propagation of electromagnetic waves carrier of energy, under the parameter of setting, electromagnetic wave is propagated with the TEM ripple in coaxial line, by measure the phase characteristic that electromagnetic wave is propagated in coaxial line, can obtain the moisture content of oil well payzone again through model calculation.Because the phase characteristic that coaxial line phase method moisture content meter adopts frequency electromagnetic waves to propagate is measured moisture content,, be fit to measure the low moisture high-water-cut oil-producing well that is fit to again measure so its measurement of water ratio scope 0～100%, and has higher resolution ratio.
Flow meter adopts two turbine mass flowmeter, and two turbine mass flowmeter can be measured by bypass flow.
Current collector adopts the cotton umbrella current collector; Double-layer umbrella muscle cotton umbrella current collector.
The beneficial effects of the utility model: the utility model horizontal well producing profile testing instrument, in being applicable to, low yield horizontal well producing profile testing.Owing to adopt coaxial transmission line as sensor, have anti-interference, the little characteristics of signal attenuation, reliable operation, its effect is good.
