Description

Method and system for collecting oil well parameters

technical field

The invention relates to the field of oil well data collection, in particular to a method and system for collecting oil well parameters.

Background technique

In thermal recovery of heavy oil, parameters such as wellhead temperature play an important role in production management. When the wellhead temperature of the heavy oil well is 60-90°C, it indicates that the production is in good condition and crude oil has been produced. When the wellhead temperature is higher than 100°C, it indicates that steam channeling occurs, the wellhead steam is mostly, and the production is very low or no production. When the wellhead temperature is lower than the ambient temperature, it means that there is no production. The range of oil production wells is wide. In the existing technology, most old factories use the original operators to manually copy the wellhead parameters. One shift station manages about 50-100 heavy oil wells. The time for personnel to transcribe is 2-4 hours. Feedback the wellhead parameters of oil wells by means of feedback, which is inefficient. In some oil production plants that adopt automation management, parameter collection is carried out by installing temperature sensors, which not only requires a large investment, but also requires opening holes in crude oil pipelines, using electric welding for operations, and laying wires at the same time, which results in high operating costs.

For the above problems, no effective solution has been proposed yet.
