Abstract
The utility model relates to a high containing water low producing oil well annular electromagnetic flow logging tool, which is used to measure the flow of the water in the high containing water low producing oil well to get the output of the oil layer. The utility model consists of an instrument head (1), a circuit tube (2), an electromagnetic flow sensor (3), a flow combining umbrella (4), and an umbrella telescoping ram (5) which are connected from up to down successively. The logging tool uses a diverter structure to separate the water and the oil gas in the mixed fluid underground, which effectively overcomes the influence to the measurement of the electromagnetic flow logging tool by non-conductive medium oil gas. The electromagnetic flow logging tool can accurately measure the flow of the water under the working condition of two-phase or three-phase flow in the oil well, combined with the whole well liquid output measured on the ground, we can get the accurate data about the oil gas output, providing a reliable basis for the dynamic analysis of the oil well output and the measures for stable production.
Description
The utility model relates to a kind of device for subsurface measuring that is used to measure high moisture stripper well reservoir withdrawal.
At present, turbo flow meter is adopted usually to the measurement of oil well reservoir withdrawal in the scene, this kind flow measurement accuracy of measurement is lower, particularly is difficult to accurate measurement especially for the moisture stripper well of height, thereby is difficult to provide reliable foundation to oil well production performance analysis and stable yields measure.By comparison, though electromagnetic flowmeter measuring accuracy height, but mainly being to be used for water injection well to measure intake profile in oil well logging instrument, is single-phase conductive fluid as the injection water of measuring object, and the oil well that contains oil gas water fluid-mixing for pit shaft does not then still have the application precedent.
Thereby the purpose of this utility model is to provide a kind of flow that can accurately measure water in the high moisture stripper well to obtain the high moisture stripper well annular space Electromagnetic Flow well logger of reservoir withdrawal.
The utility model is to realize like this.This kind traffic logger is made up of instrument head, circuit tube, electromagnetic flow transducer, current collecting umbrella and umbrella telescoping ram, its structure, assembled relation are as follows: instrument head lower end is with connection circuit tube under the screw thread, the circuit tube lower end connects electromagnetic flow transducer by sealing adaptor, connecting cylinder and connector with under the screw thread, the electromagnetic flow transducer lower end connects current collecting umbrella with under the screw thread, and the tipping of current collecting umbrella lower end has the umbrella telescoping ram.Wherein, electromagnetic flow transducer is made up of sensor urceolus, sensor skeleton, iron core, coil, measuring sonde.During use, with predetermined depth under this instrument lower going-into-well, OIH, gas, aqueous mixtures are behind the current collecting umbrella afflux, most of oil-gas accumulation is above umbrella, flow out from by-pass port, another part (mainly being water) flows into from inlet, flows out from liquid outlet after electromagnetic flow transducer is measured the flow of water in the fluid-mixing.So, can measure the flow of water in the fluid-mixing exactly for the lower oil well electromagnetic flow transducer of hydrocarbon content.In the course of the work, the square-wave signal of constant current is provided to cell winding by exciting circuit, measuring-signal on the measuring sonde through signal processing circuit amplify, detection, and the signal after will handling is delivered to driving circuit, driving circuit is delivered to the ground survey system with signal, finally obtains the downhole flow data.
The utility model adopts flow dividing structure that water in the fluid-mixing of down-hole and oil gas are separated, overcome the influence of non-conductive medium (oil, gas) effectively to electromagnetic flowmeter survey, under the operating mode of oil well two-phase or three-phase stream, accurately measure the flow of water, thereby the full well production fluid amount that can combined ground records obtains the accurate data of oil and gas production, for oil well production performance analysis and stable yields measure provide reliable basis.
