Unattended transformation system and method for oil field three-phase dehydration closed oil transportation station yard

Abstract

The invention discloses an unattended transformation system and method for an oil field three-phase dehydration closed oil transportation station yard. The output end of a ball collecting device is connected with a first heating furnace through a pipeline, and a chemical adding device is further connected to the pipeline between the ball collecting device and the first heating furnace. The output end of the first heating furnace is connected with a buffer tank through a pipeline, and the output end of the buffer tank is connected with an associated gas liquid separator and a three-phase separator through pipelines. The output end of the three-phase separator is connected with the associated gas liquid separator, an accident tank and an external transportation buffer tank through pipelines, and the output end of the accident tank and the output end of the external transportation buffer tank are connected with an external transportation pump through pipelines. The output end of the external transportation pump is connected with the first heating furnace and a second heating furnace through pipelines, and the output end of the second heating furnace is connected with a metering device through a pipeline. The output end of the metering device is connected with an external transportation pipeline through a pipeline, and all the assemblies are electrically connected with a control assembly.

Description

technical field [0001] The invention belongs to the technical field of oilfield station construction, and in particular relates to an unattended transformation system and method for an oilfield three-phase dehydration sealed oil transportation station. Background technique [0002] Existing oilfields generally span multiple provinces. Faced with the outstanding contradiction between the rigid growth of ground facilities brought about by the continuous stable production of oilfields and the company's labor shortage, unattended construction has opened up a new path to alleviate the company's labor tension. Oilfield companies Transformation and upgrading, modernization, has a strong reference. [0003] Unattended stations are the main means to reduce personnel and increase efficiency. It is necessary to improve the accuracy and stability of data collection, and adhere to the principles of safety, efficiency, and economy for construction, operation, and management. New stations...

AI Technical Summary

Problems solved by technology

[0007] 1. There is no monitoring of the ball collection device, which cannot protect the safety and equipment of the station;

[0008] 2. The existing heating furnace cannot realize automatic flameout protection and automatic load adjustment, and there is no low water level alarm function;

[0009] 3. The buffer tank cannot automatically monitor the pressure, and manual inspections are required on time, and the pressure monitoring is not timely; the outlet of the buffer tank is equipped with a manual three-way valve, and in the event of an accident, manual on-site operation is required to switch the process to the accident tank for temporary storage of oil;

[0010] 4. The external pump cannot automatically monitor the pressure, and manual inspections are required on time. The pressure monitoring is not timely, and repeated gas-liquid separation of unqualified oil is impossible;

[0011] 5. The accident tank cannot monitor the liquid level change in real time, and manual inspection is required on time. If the liquid level monitoring is not timely, it is easy to cause the tank to leak;

[0012] 6. The outlet of the three-phase separator is not equipped with a device to monitor the water content of the purified oil, so it is impossible to accurately judge whether the purified oil is qualified;

[0013] 7. The sewage pipeline of the associated gas separator is easy to be blocked and needs to be manually cleaned frequently
