Gas well flow rate data acquiring device

Abstract

The invention discloses a gas well flow data collector, comprising the following: a communication module, which is connected with an intelligent flow meter and used for transmitting flow data to an MCU; the MCU is used for regulating all modules and receiving data information transmitted by the communication module, And integrate the data information; LORA wireless module, used for large-scale transmission of integrated flow data; power supply, used to provide stable working voltage; DC / DC converter, used to convert the output voltage of the power supply to match the intelligent flow The power supply voltage of the meter; unified expansion interface, used to expand the connection path between MCU and external modules. The distance between the installation position of the present invention and the smart meter is very short, and the induction pulse introduced by the length of the connecting cable in this length interval is very small, which is not enough to pose a threat to the smart flow meter; the battery is used for power supply, no external power grid is required, the safety performance is high, and the direct The introduction of pulses by lightning strikes through the grid is avoided.

Description

technical field [0001] The invention relates to the field of remote collection of natural gas, in particular to a gas well flow data collector. 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 deserts. In the Gobi, the inspection is very inco...

Problems solved by technology

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.
