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...

[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 focus and difficulty of oilfield development. Due to the lack of professional equipment, gas and liquid cannot be mixed. Single-phase Recycling input and output are low, especially in winter, when the process increases, equipment and pipelines are easy to freeze and block, which seriously affects normal production, and a large amount of associated gas is emptied, resulting in waste of resources, and there are problems such as environmental pollution. The treatment efficiency of the oily sludge produced is low, resulting in the waste of a large amount of oil with a certain purity. Based on this, people urgently need an unattended oil and gas mixing device to solve the above problems
