Abstract

The invention discloses a measuring device of a blocking position of a gas pipeline. The measuring device comprises a gas tank, and a first Pt thermometer and an exhaust pressure-resistance valve are connected to the gas tank. The gas tank is connected with the gas pipeline through a pressure-resistance flexible pipe, a second Pt thermometer is arranged on the gas pipeline, and a first pressure-resistance valve and a second pressure-resistance valve are respectively arranged on the pressure-resistance flexible pipe. A pressure sensor is connected to the pressure-resistance flexible pipe between the two pressure-resistance valves. The invention further discloses a measuring method of the measuring device. The measuring method comprises the steps that firstly, the initial pressure and temperature of gas in the gas tank are measured; secondly, the initial pressure and temperature of gas in the gas pipeline are measured; thirdly, the two pressure-resistance valves are opened, the gas in the gas pipeline flows towards the gas tank, and the pressure and temperature of the gas in a balanced state are measured; fourthly, the two pressure-resistance valves are closed, and the exhaust pressure-resistance valve of the gas tank is opened to discharge the gas; fifthly, an algorithm module in a computer is utilized to obtain the blocking position of the gas pipeline. The measuring device of the blocking position of the gas pipeline and the measuring method of the measuring device can accurately determine the blocking position of the gas pipeline.

Description

technical field

[0001] The invention belongs to the technical field of gas pipeline clogging measurement, and relates to a gas pipeline clogging position measuring device, and also relates to a measuring method of the measuring device. Background technique

[0002] Gas pipeline transportation involves all aspects of our production and life, such as: pipeline transportation of natural gas. As the main source of civil fuel, natural gas is transported from gas wells and gas generation stations to thousands of households through pipelines. In the northern region, due to the low temperature in winter, the freezing period in some areas is long, and natural gas contains some free water, generally the water content is about 0.5 m3 / 10,000 m3 of natural gas. In winter, because the gas wells produce water in the surface pipelines, when the formation outside the gas pipelines is below zero, more condensed water and natural gas hydrates are likely to be generated in the gas well surface ...
