Abstract

The invention discloses a crude oil condensation identification method and equipment based on artificial intelligence, belongs to the technical field of petroleum industry, and solves the problem that the condensation situation of waxy crude oil in an oil pipeline cannot be obtained in real time. The method includes: drawing the variation curves of propagation sound velocity and attenuation coefficient variation curves at each node of the oil pipeline; performing feature extraction on each variation curve respectively to obtain the first curve feature vector of each variation curve; , update to the corresponding change curve, and perform feature extraction on the updated change curve to obtain the second curve feature vector; based on the first curve feature vector and the second curve feature vector, get the feature change value; based on the feature change value, Determine whether there is a sudden change in the change curve; if there is no sudden change, then determine the condensation degree of the crude oil at the node where the ultrasonic emitting device is located based on the final determined propagation speed and attenuation coefficient.

Description

technical field

[0001] The present application relates to the technical field of petroleum industry, in particular to an artificial intelligence-based crude oil condensation recognition method and equipment. Background technique

[0002] Pipeline transportation of high pour point and high viscosity crude oil is a complex process. However, the waxy crude oil in the high pour point and high viscosity crude oil is a complex mixture of multi-component hydrocarbons and non-hydrocarbons. During the production and transportation process, as the temperature decreases, the wax crystals in the crude oil will continue to precipitate. And crosslink each other to form a network structure with a certain strength, and then present the so-called gelation phenomenon. Therefore, at present, waxy crude oil is mainly transported by heating pipelines to ensure the fluidity of waxy crude oil in the pipeline.

[0003] However, the composition and flow state of the crude oil produced in the actua...
