[0002]There are a large amount of oilfield crude oil in our country that needs to be heated and exported. It is necessary to separate the gas and liquid. The liquid is heated and exported, and the gas is exported separately. Not airtight, the site process is more complicated
At the same time, due to the low temperature of crude oil and the extension of oil field development, the water content of the oil field is getting higher and higher. In order to meet the requirements of external transportation and dehydration, a large amount of crude oil or natural gas is required to heat the water-containing crude oil, and the conventional energy consumption is large.

The invention discloses an oil field ground collecting and conveying system and collecting and conveying method. The oil field ground collecting and conveying system comprises a total mechanism device, a ball collecting barrel device, a new energy heating device, a temporary storage device, an oil and gas mixing and conveying pump, an external conveying system and a control system. The main mechanism device is connected with the ball collecting barrel device through a pipeline, an outlet of the ball collecting barrel device is connected with the new energy heating device through a pipeline, and the temporary storage device is arranged behind the new energy heating device for storage of the fluid; and the new energy heating device inputs fluid to the external conveying system through the oil and gas mixing and conveying pump after the fluid is heated, and the control system controls the ball collecting barrel device, the new energy heating device, the temporary storage device and the oil and gas mixing and conveying pump through a cable. By the adoption of the system, the station process flow is simplified, the oil field crude oil collection, conveying and heating requirements are met, the conventional fossil energy consumption is reduced, the oil and gas are mixed and conveyed in a fully closed manner, the safety and environmental protection are achieved, and the construction investment and the later production operation cost are reduced.
Description
technical field [0001] The invention belongs to the technical field of oilfield surface gathering and transportation, and in particular relates to an oilfield surface gathering and transportation system and a gathering and transportation method. Background technique [0002] There are a large amount of oilfield crude oil in my country that needs to be heated and exported, and the gas and liquid need to be separated. The liquid is heated and exported, and the gas is exported separately. The crude oil separation buffer tank is added, not airtight, and the site process is more complicated. At the same time, due to the low temperature of crude oil and the increasing water content of the oilfield with the extension of oilfield development, in order to meet the requirements of export and dehydration, a large amount of crude oil or natural gas is required to heat the water-containing crude oil, and the conventional energy consumption is large. Contents of the invention [0003] I...
