Problems solved by technology

[0002] At present, with the development of measurement and control technology, especially the fine management of the petroleum industry, the requirements for the oil well production measurement system are getting higher and higher; the traditional crude oil single well measurement and measurement system has a single design function, and its measurement accuracy is low due to the complex composition of the oil well production medium , Impurities in the medium or low-temperature condensate lead to a large amount of on-site maintenance of the equipment, and the single signal processing leads to low automatic processing capabilities, which require continuous calibration and are increasingly unable to meet the requirements of modern metrology.

Abstract

The invention discloses a crude oil single well metering and measuring system which comprises a shell, a main controller, a receiving terminal, a flow measuring assembly, a density measuring assembly and a temperature measuring assembly. The shell comprises an inner layer shell body and an outer layer shell body, and heat insulation cotton is arranged between the inner layer shell body and the outer layer shell body. A heat guide oil storage chamber is arranged in the inner layer shell body, and an explosion-proof box support is arranged on the outer layer shell body. An explosion-proof box is connected to the explosion-proof box support, and a transverter, an air switch and a tracing ribbon are arranged in the explosion-proof box. The tracing ribbon is located in the transverter. The air switch controls the tracing ribbon to be started and stopped. The flow measuring assembly is arranged in the inner layer shell body, and the density measuring assembly and the temperature measuring assembly are both arranged on the outer layer shell body. The flow measuring assembly, the density measuring assembly and the temperature measuring assembly are all in signal connection with the main controller, and the main controller is in signal connection with the receiving terminal. The metering precision of an oil well is improved, the using cost of an oil well metering instrument is reduced, and the metering efficiency of the oil well is improved.
