The invention discloses a high-pressure gas conveying pipe leakage monitoring system and method. The high-pressure gas conveying pipe leakage monitoring system comprises a first data acquiring and processing device, a first flow sensor, a first vibration signal sensor, a first pressure sensor and a first temperature sensor arranged on a first section of a high-pressure gas conveying pipe, and a second data acquiring and processing device, a second vibration signal sensor, a second pressure sensor and a second temperature sensor arranged on a second section of the high-pressure gas conveying pipe; the first section is positioned at the upstream of the second section; the first flow sensor, the first vibration signal sensor, the first pressure sensor and the first temperature sensor are connected with the first data acquiring and processing device; and the first data acquiring and processing device is used for processing data acquired by the first flow sensor, the first vibration signalsensor, the first pressure sensor and the first temperature sensor to obtain first data to be analyzed.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas delivery, in particular to a system and method for monitoring leakage of a high-pressure gas delivery pipeline. Background technique [0002] In the process of oil extraction, in order to increase production, technical means will be used to carry out oil displacement operations in underground oil layers, in which high-pressure pipelines are used to continuously inject CO into the oil layers. 2 It is a technology that is gradually becoming mature. [0003] Normally, CO 2 It is driven into the delivery pipeline by a high-pressure (10-20Mpa) pump and transported to the injection point. The delivery pipeline will be continuously under high-pressure operation (for example, 19Mpa operation), and the CO in the pipeline will 2 Generally, it is in a liquid state. Once such a high-pressure operation pipeline leaks and cannot be found in time, it will seriously affect the recovery rate of crude o...
