Unattended oil-gas mixed transportation process device

Abstract

The invention discloses an unattended oil-gas mixed transportation process device which comprises a mixed transportation assembly and an intelligent sensing control system. The mixed transportation assembly is used for realizing oil-gas mixed transportation, the mixed transportation assembly comprises a plurality of oil-gas mixed transportation pumps and dirty oil recovery assemblies, the plurality of oil-gas mixed transportation pumps are communicated in series through pipelines, and the multiple oil-gas mixed transportation pumps are all provided with control valves; and the intelligent sensing control system is used for controlling the control valves to enable the oil-gas mixed transportation pumps to operate, the pipelines are further provided with the dirty oil recovery assemblies and buffer tanks, and the buffer tanks are used for oil-gas separation. The unattended oil-gas mixed transportation process device is scientific and reasonable in structure and safe and convenient to use, large-displacement and high-oil-gas-ratio oil-gas mixed transportation can be achieved through the oil-gas mixed transportation pumps 1, the oil and gas directly enter the oil-gas mixed transportation pumps to be transported outwards, technological processes and capital investment are reduced, automatic control is achieved, stations are unattended, labor cost is reduced, oil-gas mixed transportation is achieved, and emission pollution of associated gas can be effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of oil field oil transportation, in particular to an unattended oil and gas mixed transportation process device. Background technique

[0002] During the extraction of oil, a lot of natural gas will be produced. For every ton of oil produced, dozens to hundreds of cubic meters of natural gas will be produced. For example, the gas-oil ratio in Changqing Oilfield ranges from 60 to 120 m 3 / t, in the actual production of oil fields, many oil transfer sites will produce a lot of associated gas, associated gas is wet gas, which is a kind of natural gas, when the temperature is low, condensate oil and water will be precipitated during the transportation process, which needs to be carried out Gas-liquid separation and transportation requires a lot of equipment investment, high difficulty in management, high quality requirements for personnel, and high work intensity. Oilfield associated recovery has always been the...
