A vehicle-mounted single water tank type oil field water meter field calibration device and calibration method

Abstract

The invention discloses a vehicle-mounted single water tank type oil field water gauge field calibration device and calibration method. The device includes: a liquid level tube, a water tank, a pressure jack placement tank, a hydraulic jack, an electronic scale, a steady flow tube, a standard gauge car, etc. The liquid level tube is installed on the top of the water tank, the water tank is installed on the electronic scale, the four corners of the bottom of the water tank are provided with a hydraulic jack placement groove, and a hydraulic jack is installed under the hydraulic jack placement groove, and the external hose , Steady flow pipe, standard meter, rear straight pipe section, regulating valve, main valve, three-way valve, hose and front straight pipe section are all resistant to high pressure, and the steady flow pipe is honeycomb small hole type. The calibration method adopts the combination of the standard meter method and the weighing method. The standard meter method is used to compare and measure the tested meter, and the weighing method is used to periodically calibrate the standard meter under the condition of high-pressure turbid water on site. The invention solves the problems that the standard meter cannot be regularly calibrated on the spot and the inspected oil field water meter cannot be accurately detected in the field environment.

Description

technical field [0001] The invention relates to the field of oilfield water meter detection, in particular to a vehicle-mounted single water tank type oilfield water meter field calibration device and a calibration method. Background technique [0002] Water meter is an important measuring instrument in the oil production process, and it is widely used and widely distributed in oil field water injection wells and pump rooms. At present, the calibration of oilfield water meters is not perfect, and many water meters are in a long-term unchecked state due to the trouble of disassembly and assembly when sending them to the laboratory for inspection, and the need to replace them with spare meters, otherwise the normal production of the oilfield will be affected. [0003] Although the current water flow calibration device in the laboratory is mature in technology, it is bulky, and due to the poor traffic conditions at the oil field site, it is still impossible to calibrate the tes...
