Abstract

The invention discloses a system for removing surface impurities of gas field flow measurement device, including a main system. The system comprises a pipeline module and a control module, wherein thepipeline module comprises a first air inlet pipe, a measuring circuit, a dust outlet pipe and a first air outlet pipe. The first air inlet pipe is connected with the measuring circuit at the first interface, and the dust outlet pipe is connected with the measuring circuit. The first air outlet pipe is connected with the second interface at the middle part of the dust pipe; the measuring circuit includes a four-way change-over ball valve and a detection pipe, and the four-way change-over ball valve is arranged at the connection of the dust outlet pipe and the measuring circuit. By switching between the main system and the standby system, the standby system can be started in case of failure of the main system, so as to achieve the purpose of uninterrupted measurement. The flow can be measured while the impurities are cleaned, and the cleaning effect of the two-way impurity removal method is more excellent.

Description

technical field [0001] The invention relates to the technical field of gas field metering, in particular to a system and method for removing surface impurities of a gas field flow measuring device. Background technique [0002] With the enhancement of global environmental protection awareness, people's demand for energy is getting higher and higher. The excessive use of traditional coal, oil and other energy sources has brought great pollution to the environment. Therefore, my country's demand for clean energy continues to increase, and oil and gas fields, The exploration and development of natural gas fields are also paid more attention to. In the process of gas field exploitation, accurate measurement of the extracted oil and gas and natural gas ensures the safe and reliable transportation of gas, which is conducive to providing scientific and accurate data for subsequent exploitation and resource allocation, which must involve the use of flow measurement devices. [0003]...
