Vehicle-mounted double-water-tank type oilfield water meter field calibration device and method

Abstract

The invention discloses a vehicle-mounted double-water-tank type oilfield water meter field calibration device and method. The calibration device comprises a standard water tank, handles, a water storage tank, a testing pipeline, an electronic scale, a pickup truck, a shell, a barretter, a standard meter and the like, wherein reinforcing ribs are mounted on the left side and the right side of thestandard water tank; the handles are mounted on the reinforcing ribs; the electronic scale is mounted on the water storage tank; an external hose, the barretter, the standard meter, a rear straight tube section, an adjusting valve, a main valve, a three-way valve, a hose and a front straight tube section resist pressure of 25 MPa; and the barretter is in the type of honeycomb small holes. According to the calibration method, a mode of combining a standard meter method and a weighing method is adopted, a detected meter is comparatively measured by the standard meter method, and the standard meter is calibrated at regular intervals under the condition of field high-pressure muddy water by the weighing method. The problems that the standard meter cannot be calibrated at regular intervals in field, and the water meter of a detected oilfield cannot be accurately detected in a field environment are solved.

Description

technical field [0001] The invention relates to the field of oil field water meter detection, in particular to a vehicle-mounted double water tank type oil field 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 t...
