Abstract

A transient flow problem method-based oil pipeline dropping detection device belongs to the field of operation and maintenance of a long-distance oil pipeline. The invention aims to solve the problems that the existing quantitative and positioning device for detecting the dropping of the oil pipeline is high in use cost and time-consuming and is easily influenced by environment. The transient flow problem method-based oil pipeline dropping detection device comprises a processor, a storage, a data collecting card and M pressure sensors; the M pressure sensors are uniformly arranged on the oil pipeline; the pressure signal output end of each pressure sensor is connected with the pressure signal input end of the data collecting card of which the pressure signal output end is connected with the pressure signal input end of the processor; the data transmission end of the processor is connected with the data transmission end of the storage; the processor processes the collected pressure signal in real time, and a transient flow problem method is adopted for judging whether the oil pipeline dropping exists or not.

Description

technical field [0001] The invention relates to a device for detecting leakage of an oil pipeline based on a transient flow inverse problem method, and belongs to the field of long-distance oil pipeline operation and maintenance. Background technique [0002] Oil pipelines play an important role in national economy and military tasks. With the rapid increase of pipeline transportation mileage in our country, the transportation capacity has been greatly improved. However, the construction quality of pipelines, long-term operation, aging, corrosion, and oil theft incidents seriously affect the normal operation of oil and gas fields, which not only seriously affects the national economy and military tasks, but also pollutes the surrounding environment. At present, the oil pipeline leakage detection technology used in the oilfield field can only detect large leakage accidents, but cannot accurately detect and locate small leakages. [0003] Commonly used leak detection techniq...
