Oil field gas metering data remote transmission device

Abstract

The invention discloses a remote transmission device for oil field natural gas metering data, which includes a safe area and an explosion-proof area. A concentrator is arranged in the safe area, and a plurality of interconnected wireless collection front ends and flow meters are arranged in the explosion-proof area; the concentrator uses The measurement data of the wireless acquisition front-end is collected from a safe distance, and the measurement data is uploaded to the remote transmission platform through the data upload module, or the measurement data is transmitted to the metering system and the station control system through the local port for processing; the wireless acquisition front-end is used It is used to collect the measurement data of the flowmeter and transmit it to the concentrator wirelessly; the flowmeter is used to detect the gas flow in the natural gas pipeline. When the measurement data is transmitted locally, the measurement data can be transmitted stably and accurately to the metering system and station control system through interfaces such as RS485 or RJ45.

Description

technical field [0001] The invention relates to the field of remote collection of natural gas, in particular to a remote transmission device for metering data of natural gas in an oil field. Background technique [0002] At present, my country's natural gas resources are not very rich, and the regional distribution of reserves is very uneven. In recent years, with the rapid development of the global economy and the enhancement of the awareness of global environmental protection, the demand for natural gas as the cleanest energy is increasing. It is becoming more and more urgent. In some low-permeability areas of our country, the exploitation of natural gas is also in full swing. If natural gas is exploited in these areas, high-density natural gas wells are required to obtain high natural gas production. Therefore, tens of thousands of natural gas wells are distributed in a county-level administrative region. Due to the large number of wellheads, they may be distributed in des...

If natural gas is exploited in these areas, high-density natural gas wells are required to obtain high natural gas production. Therefore, tens of thousands of natural gas wells are distributed in a county-level administrative region. Due to the large number of wellheads, they may be distributed in deserts. In the Gobi, the inspection is very inconvenient, and the gas field must be managed digitally and networked. Therefore, it is necessary to have a supporting natural gas wellhead data collection and remote transmission system

In the natural gas wellhead data acquisition system in the prior art, the remote terminal control unit RTU (Remote Terminal Unit) collects wellhead oil pressure, casing pressure and natural gas flow data in the natural gas export pipeline through the analog input channel. Due to the limitation of channels, it is impossible to complete data collection for equipment above four cluster well groups. Moreover, the natural gas wellhead data collection system in the prior art still has defects and deficiencies such as high power consumption, poor safety performance, and high maintenance costs after failure.
