Problems solved by technology

[0002] Oil well products usually contain oil and natural gas. Separately transporting oil and natural gas requires the erection of a large number of pipelines to distinguish between gas and liquid, which will greatly increase the transportation cost, and the resistance during oil transportation is relatively large, and the fluidity is relatively low. It is beneficial to quickly transport oil to the production site, so it is necessary to develop a mixed oil and gas pipeline to solve the problem that oil well products usually contain oil and natural gas, and the separate transportation of oil and natural gas requires the erection of a large number of pipelines to distinguish between gas and liquid , will greatly increase the transportation cost, and the resistance in the oil transportation process is relatively large, and the fluidity is relatively low, which is not conducive to the problem of quickly transporting oil to the production site

Abstract

The invention discloses an oil-gas mixed conveying pipeline. The oil-gas mixed conveying pipeline structurally comprises an oil well oil pipe, a flow dividing and gas collecting device, an oil conveying pipe, an exhaust pipe, a motor, a gas collecting and pressure releasing device, a support and a lifting rod. The pipeline has the effects that the oil well oil pipe is connected with an oil well, gas contained in an oil layer is output along with the oil well oil pipe; under action of the flow dividing and gas collecting device, oil is separated from part of the gas; under the cooperation of the flow dividing and gas collecting device and the gas collecting and pressure releasing device, the gas is collected in the gas collecting and pressure releasing device in a centralized mode; when thegas is collected to a certain capacity, the lifting rod works, a movable inner rod is connected with a transmission vertical shaft, and the transmission vertical shaft rotates under the driving torque generated by the motor; a piston is driven to compress the gas, and the gas is pressurized and then discharged into the oil conveying pipe from the exhaust pipe to be mixed with the oil; and fluidity of the oil in the oil conveying pipe is improved through fluidity of the pressurized gas, resistance of the oil and the pipe wall of the oil conveying pipe is reduced, and the oil can be rapidly conveyed to a processing place.
