Abstract

The invention relates to an oil leak detection method and a system based on a visual image, wherein, the detection method comprises the following steps: S1, obtaining a monitoring image; 2, selectinga region of interest from that monitor image; 3, extracting a foreground image from that region of interest by a frame difference method, and judging whether a specific connected region exists in theforeground image; S4, performing HSV format conversion on the specific connected regions corresponding to the original graph; S5, comparing the specific connected area after HSV format conversion withthe set HSV threshold value, and if the threshold value of the specific communication area is larger than the set threshold value, performing oil leakage alarm, otherwise, performing the next frame difference detection. The detection method and the detection system of the invention can be well applied to carry out more efficient oil leakage detection in an oilfield operation area, and the detection accuracy and stability are high, and the detection cost is low.

Description

technical field [0001] The invention relates to the technical field of oil leakage detection, in particular to an oil leakage detection method and a detection system that can be used in oil field operation areas. Background technique [0002] Petroleum is a fluid mineral buried deep in the ground and is an important energy source. Oil and gas extraction is the process of extracting oil and natural gas buried in underground oil layers from the ground. The way oil and gas are extracted from the ground to the surface can be divided into self-injection and artificial lift according to whether artificial energy needs to be added to the wellbore fluid. Artificial lift oil recovery includes: gas lift oil recovery, pumping unit rod pump oil recovery, submersible electric centrifugal pump oil recovery, hydraulic piston pump oil recovery and jet pump oil recovery, etc. In the process of exploiting oil on land, the oil is pumped to the surface by the pumping unit, and then drained in...
