Abstract

The invention relates to the field of artificial intelligence, in particular to an oil and gas well liquid level intelligent monitoring method and device. Characteristic data in the oil and gas well in the current time period are collected; calculating the abnormal degree of the feature data at each moment; calculating the transmission urgent degree of the feature data; grading the feature data in the current time period, and calculating an adjustment coefficient of the feature data of each grade; constructing an adjustment coefficient sequence of each level of feature data; performing Huffman coding according to the adjustment coefficient sequence of the feature data of each level in the current time period, correcting the duration of the next acquisition time period to obtain a coding result of each time period, and transmitting the coding result; and decoding the coding result to obtain oil and gas well characteristic data, and regulating and controlling oil and gas well parameters according to the abnormal degree of the characteristic data. According to the method, the problem that the abnormal data is not the shortest code value in the traditional Huffman coding is solved by calculating the adjustment coefficient, and the rapid and accurate transmission of the abnormal data can be realized.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method and device for intelligent monitoring of liquid level in oil and gas wells. Background technique [0002] Oil and gas wells are affected by flow pressure drop during the production process, and the output and flow rate at different positions are quite different; due to the large amount of fluid output in the high-permeability section, the output inrush effect is particularly obvious, and the resulting uneven profile, Once it encounters water or gas, it is easy to cause coning, which leads to the obstruction of fluid outflow in some liquid-producing sections, and the production of oil and gas wells will be greatly reduced. It has also been continuously updated. At this stage, there has been a flow regulating water control screen that can automatically adjust the inflow resistance according to the formation liquid production situation. With the development of flow r...
