Description

Technical Field

[0001] This utility model belongs to the field of petroleum equipment technology, specifically relating to a high-precision dual-body tracer metering device. Background Technology

[0002] A dual-unit metering device is a system specifically designed for the processing and precise measurement of two different fluids, such as oil, natural gas, or chemicals. These devices typically consist of two independent operating units, each capable of handling one fluid separately and precisely controlling the mixing ratio or metering them individually.

[0003] When sampling fluids from the wellhead of a sampling well, traditional methods, whether manual sampling without metering equipment or single-tank metering systems, struggle to accurately separate and measure the proportions of oil / gas or water. This results in inaccurate metering data, affecting the scientific and rational nature of subsequent production decisions and hindering timely sampling and metering of tracers in the produced fluid. Furthermore, the lack of precision in sampling and metering data for oilfield tracers fails to meet the demands of modern oil and gas development for refined management of fluid composition.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figure 1-5 The present invention provides the following technical solution:

[0037] A high-precision dual-body tracer metering device includes:

[0038] First oil tank 1;

[0039] The second oil tank 2 is located on one side of the first oil tank 1. The oil inlet pipes of both the first oil tank 1 and the second oil tank 2 are fixedly connected to the first electric three-way valve 3.

[0040] The third oil tank 14 is located on one side of the first oil tank 1. The oil outlet pipes of the first oil tank 1 and the second oil tank 2 and the oil inlet pipe of the third oil tank 14 are all fixedly connected to the second electric three-way valve 4.

[0041] Two first tracer sampling and metering devices 5 are each disposed on the circumferential surface of the second electric three-way valve 4. An exhaust pipe 6 and a drain pipe 8 are disposed on the outer surface of the third oil tank 14. A second tracer sampling and metering device 10 is disposed on the circumferential surface of the drain pipe 8.

[0042] A stirring mechanism is installed on the lower side of the third oil tank 14 to stir and mix the petroleum inside the third oil tank 14.

[0043] In a specific embodiment of this utility model, the first oil tank 1 and the second oil tank 2 are used to store two different types of petroleum or different batches of the same type of petroleum, respectively. Both oil tanks are equipped with inlet pipes. A first electric three-way valve 3 is used to control the flow direction of oil entering the first oil tank 1 and the second oil tank 2. The valve is operated according to the external control system to change the fluid path and ensure precise control of flow rate and direction. When the first oil tank 1 is filled with liquid, the second oil tank 2 is discharged. The liquid volume is measured by real-time liquid level changes. When the first oil tank 1 is full, the first electric three-way valve 3 is controlled by the external control system to automatically switch to the second oil tank 2 for filling and the first oil tank 1 for discharging. This process is repeated, and the continuous flow from the oil well is divided by the alternation of filling and unloading of the first oil tank 1 and the second oil tank 2. During the filling process of the first oil tank 1 and the second oil tank 2, the weight of each tank is measured. Finally, the external control system automatically... The accumulated liquid storage values ​​of the first oil tank 1 and the second oil tank 2 each time are used to measure the continuous flow of liquid from the oil well. The second electric three-way valve 4 is used to control the oil flow from the first oil tank 1, the second oil tank 2 to the oil outlet pipe of the third oil tank 14. This valve can regulate and distribute the oil flow from the two oil tanks so that it can be mixed in the required proportion and flow into the third oil tank 14. The two first tracer sampling and metering devices 5 are used to sample and meter the oil from the two oil tanks before tracer addition so that it can be analyzed before the oil flows into the third oil tank 14. The exhaust pipe 6 is used to discharge excess air or other gases in the third oil tank 14. The gas flow meter 7 is used to monitor the volume of the discharged gas. During the injection process, as the liquid enters the oil tank, the internal air is compressed and discharged through the exhaust pipe 6. The gas flow meter 7 records this process. The drain pipe 8 and the liquid flow meter 9 are used to discharge the treated liquid.Liquid flow meter 9 measures the amount of liquid flowing out. When the mixed liquid needs to be discharged, it flows out through drain pipe 8, and liquid flow meter 9 ensures the correct discharge volume. Second tracer sampling and metering device 10 is used for final sampling and tracer content measurement of the mixed petroleum, ensuring that final testing is completed before the petroleum leaves the system, thereby achieving secondary sampling and tracer content measurement of the petroleum. Through two independent dual tanks, the proportions of oil, gas, and water can be efficiently separated and measured separately, ensuring highly accurate data for each fluid, thus providing a reliable basis for production decisions. Based on the first tracer sampling and metering device 5 and the second tracer sampling and metering device 10, it is possible to... Timely and accurate sampling and metering of oil before and after entering the system are essential to ensure the accuracy of tracer content and meet the demands of refined fluid composition management in modern oilfield development. It should be noted that the specific models of the first electric three-way valve 3, the second electric three-way valve 4, the first tracer sampling and metering device 5, the gas flow meter 7, the liquid flow meter 9, and the second tracer sampling and metering device 10 used are to be selected by those skilled in the art. Furthermore, the aforementioned components—including the first electric three-way valve 3, the second electric three-way valve 4, the first tracer sampling and metering device 5, the gas flow meter 7, the liquid flow meter 9, and the second tracer sampling and metering device 10—are all existing technologies and will not be elaborated upon in this solution.

When the mixed liquid needs to be discharged, it will flow out through the drain pipe 8, and the liquid flow meter 9 ensures the correct discharge amount. The gas flow meter 7 is used to monitor the volume of the discharged gas. During the filling process, as the liquid enters the oil tank, the internal air is compressed and discharged through the exhaust pipe 6. The gas flow meter 7 records this process.

The three driven gears 20 mesh with the internal gear ring 18, and under the action of force, it drives the internal gear ring 18 to rotate, thereby strengthening the rotation intensity of the three driven gears 20.
