Description

Technical Field

[0001] The present invention relates to the technical field of oil extraction, in particular to an intelligent water distributor. Background Art

[0002] After an oil field is put into development, it is necessary to inject water into the oil field in order to make up for the underground deficit caused by crude oil extraction, maintain or increase the oil layer pressure, and achieve high and stable production of the oil field. Therefore, an intelligent water distributor is needed.

[0003] In fields like oil extraction, traditional water distributors are typically mechanical, requiring manual operation or simple mechanical control to distribute water to different reservoirs. This approach has limited accuracy and struggles to accurately meet the precise water requirements of different reservoirs.

[0004] Traditional water distributors are unable to obtain real-time data on downhole flow, pressure, and other data, making it difficult for operators to adjust water distribution plans in a timely manner according to the actual conditions of the reservoir, which has a certain impact on the reservoir development effect.

[0005] With the continuous advancement of sensor technology, high-precision flow sensors, pressure sensors, etc. can accurately measure various parameters underground, making it possible for intelligent water distributors to obtain data in real time.

[0006] The development of intelligent control technologies, such as microprocessors and advanced algorithms, enables water distributors to automatically adjust water distribution flow according to preset rules and real-time monitoring data, realizing intelligent water distribution control.

[0007] The development of communication technologies, such as wireless communication and fiber optic communication, has solved the problem of data transmission between underground and the ground, allowing operators to remotely monitor and manage smart water distributors on the ground.

[0008] To improve oil reservoir recovery, it's necessary to meticulously develop the reservoir and precisely control the water injection rate for each oil layer to achieve balanced exploitation and long-term stable production. Intelligent water distributors can adjust water distribution plans in real time based on reservoir dynamics to meet the requirements of meticulous development.

[0009] By precisely controlling the water injection volume through the intelligent water distributor, unnecessary waste of water resources and energy consumption can be avoided, the efficiency of the water injection system can be improved, production costs can be reduced, and it is in line with the development trend of energy conservation and environmental protection.

[0010] Although the existing technology has effectively improved the sealing reliability of the water distributor, it still has certain shortcomings during use: the existing technology does not have a supporting mechanism and cannot firmly support the intelligent water distributor, which can easily cause it to shake during use, thereby reducing the use effect of the intelligent water distributor.
