The skid‑mounted single‑well oil‑gas separator is tailor‑made for remote scattered wells and marginal low‑yield wells. Fully integrated on skid and pre‑commissioned in factory, it can be put into service right after on‑site positioning, greatly cutting civil‑work and installation time, making it the preferred pre‑processing device for pipeline‑free single wells. Cooperating with Crude Oil Heater and Crude Oil Heat Exchanger, it heats and conditions high‑viscosity, high‑water‑cut wellhead inflow to enlarge oil‑water density difference and boost separation performance. Processed crude oil flows straight into Single Well Oil Storage Tank for temporary storage before tanker haul‑off, while sewage and associated gas are diverted for respective disposal. Reserved with standard thermal interfaces, the skid unit directly connects Solid‑state Energy Storage Heating Equipment, Multi‑energy Coupled Crude Oil Heating Equipment and New Energy Zero‑carbon Heating Equipment, enabling rapid zero‑carbo…
