The pressure-type single well oil tank is a ground-mounted pressure-bearing vessel specially designed for scattered low-yield oil wells with stable wellhead pressure and no gathering pipeline conditions. It relies on internal natural oil and gas pressure to realize automatic tanker loading without elevated structure, greatly simplifying well site civil construction. The equipment can operate in linkage with complete oilfield thermal devices, using Crude Oil Heater and high-efficiency Crude Oil Heat Exchanger to maintain constant temperature for internal medium, ensuring stable crude oil fluidity and preventing solidification, wax deposition and blockage in low-temperature field environments. It supports full new energy system expansion and stably connects Solid-state Energy Storage Heating Equipment, Multi-energy Coupled Crude Oil Heating Equipment and New Energy Zero-carbon Heating Equipment. Together with Single Well Oil Storage Tank, it forms a composite wellhead storage and heating…
