Intelligent early warning and automatic intervention system for oil well mouth parameters

Abstract

The invention relates to an intelligent early warning and automatic intervention system for oil well mouth parameters. The system comprises a current acquisition module, a well temperature acquisition module, an oil pressure acquisition module, a casing pressure acquisition module, a control module and a flow automatic control instrument installed on a thin oil mixing pipeline; wherein the current acquisition module is used for acquiring current data of a motor of the oil pumping unit; the well temperature acquisition module is used for acquiring oil return temperature data during oil well blending adjustment; the oil pressure acquisition module is used for acquiring oil pressure data of an oil pipe, and the casing pressure acquisition module is used for acquiring casing pressure data; the control module can receive motor current data, oil return temperature data, oil pressure data and casing pressure data of the oil pumping unit so as to generate a target blending amount and send the target blending amount to the flow automatic control instrument; and the flow automatic control instrument is used for automatically controlling the thin oil blending flow according to the target thin oil blending amount. According to the system, the blending accompanying conveying amount can be automatically adjusted in real time according to well condition parameters of an oil well mouth, the blending amount is optimized in time, manual intervention is not needed, and intelligent blending is achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic regulation and control of oilfield mixed-dilution pipe network, and in particular relates to an intelligent early warning and automatic intervention system for oil wellhead parameters. Background technique [0002] Oilfield diluting is one of the important means to supplement energy to formation, improve fluidity and enhance oil recovery in the process of oilfield development. Due to the high viscosity of heavy oil, there is a lot of resistance in the process of flow, and it is not easy to pump out from the oil well. The thin oil is injected downhole through high pressure, which can achieve the purpose of diluting the heavy oil and ensure the pumping effect. The dilution amount of traditional oil wells is regulated by manually adjusting the opening of the wellhead dilution valve on a single dilution pipeline. With the deepening of oilfield development, more and more infill wells and peripheral w...

Problems solved by technology

However, the value set by the high-pressure flow automatic control instrument still depends on manual adjustment, but when adjusting the parameters at the wellhead of remote wells, well patrol personnel need to adjust the given value on site, so the timeliness is poor, and a slight delay may easily cause oil well abnormalities
