Combined low-temperature consumption-reducing and exploitation-increasing oil transportation device

Abstract

A combined low-temperature consumption-reducing and exploitation-increasing oil transportation device comprises a mixed medium splitter. The mixed medium splitter is provided with a mixed medium input port, a mixed medium liquid transportation pipeline, a separated waterpower supply pipeline and an emergency bypass pipeline; the mixed medium liquid transportation pipeline is sequentially provided with an entrance valve, an entrance temperature and pressure display device, a medium steady-state separation vortex processor, a mixed power vortex acceleration processor, a three-level waterpower vortex speed regulation processor, an exit temperature and pressure display device and an exit valve. The combined low-temperature consumption-reducing and exploitation-increasing oil transportation device can realize back pressure of a wellhead of an oilfield and the reduction value of greater than 0.1 MPa, can reduce the temperature of a medium in a mining liquid conveying pipeline on the ground, can prolong the service life of more than 2 years, and achieves the functions of being skid-mounted, maintained, repaired, assembled and disassembled rapidly. The combined low-temperature consumption-reducing and exploitation-increasing oil transportation device is suitable for an oil production well adopting a low-temperature collection and transportation production technology with the water content of a produced liquid at the wellhead greater than 60%.

Description

Technical field: [0001] The invention relates to a combined low-temperature consumption-reducing oil production-increasing device, which belongs to an integrated mechanical device for reducing oil well back pressure, preventing pipeline scaling and waxing, and increasing efficiency and reducing consumption in oil field oil pipelines. Background technique: [0002] At present, in the petroleum industry, with the continuous deepening of oilfield development, the difficulty of stable production and development of oilfields has increased year by year. Efforts to control production energy consumption and continuously reduce investment costs have become the focus of efficient oilfield development. However, at present, after some single-well oil-gathering pipelines are in production, after the single-pipe oil-gathering operation is implemented, the wax deposition speed of the pipeline is faster than that in the normal water-mixing period, and the oil return pressure increases accord...
