Abstract

The invention discloses a dynamic liquid level automatic monitoring device and an operating method thereof. The dynamic liquid level automatic monitoring device comprises an air storage tank, a boosting pump and testers. An air inlet of the air storage tank is connected with a nitrogen generating unit; an air outlet of the air storage tank is connected with the boosting pump; an outlet of the boosting pump is provided with a plurality of pipes, which are connected with a plurality of testers by means of parallel networking. The dynamic liquid surface automatic monitoring device of the invention adopts an inert gas nitrogen as a sounding source and is measured in an outside-to-inside inflation manner, which meets safety and environmental protection requirements, is suitable for a wellhead with a pressure of 0-5 MPa; a wide monitoring range is achieved, and various well conditions of an oil field are met.

Description

technical field [0001] The invention belongs to the technical field of ground automatic control of oil production engineering, and in particular relates to a dynamic liquid level automatic monitoring device and an operation method thereof. Background technique [0002] At present, the monitoring methods of the dynamic liquid level mainly include the pressure sensor test, emptying the shell, and the pneumatic sound source test. Due to the problems of inconvenient operation, lack of safety and reliability in the pressure sensor test and the emptying gun test, they are not suitable for use as On-line monitoring of fluid level. Considering various factors, we decided to adopt the liquid level online monitoring technology of pneumatic sound source. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dynamic liquid level automatic monitoring device and its operation method for the deficiencies in the above-mentioned pri...
