Gas well remote information acquisition system

Abstract

The invention discloses a gas well remote information acquisition system comprising the following units: a communication module jointed with an intelligent flowmeter and used for transmitting flow data to a MCU; the MCU used for modulating all modules, receiving data information transmitted by the communication module, and integrating the data information; an LORA wireless module with a model number of F8L10 and used for transmitting integrated flow data in a large scope; a power supply being a plumbic acid battery and used for providing stable work voltage; a DC / DC converter used for converting the power supply output voltage so as to match with the power supply voltage of the intelligent flowmeter; an uniform expansion interface used for expanding the connecting paths between the MCU andexternal modules. The gas well remote information acquisition system is installed in a position very close to the intelligent flowmeter; the induction pulse introduced by the connecting cable withinsaid length range is very small, and cannot affect the intelligent flowmeter; the power supply uses the battery, so no external power grid is needed, thus improving safety performance, and directly preventing lightning stroke from introducing pulses through the power grid.

Description

technical field [0001] The invention relates to the field of gas well exploitation, in particular to a remote information collection system for gas wells. Background technique [0002] In the natural gas wellhead data acquisition system in the prior art, the remote terminal control unit RTU (RemoteTerminal Unit) collects wellhead oil pressure, casing pressure and natural gas flow data in the natural gas export pipeline through the analog input channel. However, the data acquisition cannot be completed for equipment above four cluster well groups. Moreover, the natural gas wellhead data acquisition system in the prior art still has defects and deficiencies such as high power consumption, poor safety performance, and high maintenance cost after failure. Contents of the invention [0003] The object of the present invention is to provide a remote information acquisition system for gas wells to solve the above-mentioned defects. [0004] The object of the present invention is...
