The invention provides a method for multilayered series overlapped development of small-type station field gathering and transferring treatment, which is applied to oil extraction ground gathering and transferring treatment in an oil-gas field. The method is characterized in that: a layered series primary oil well is connected with a layered series primary station inlet manifold; a layered seriesprimary oil inlet manifold is connected with a raw oil inlet of a layered series primary oil inlet heating furnace; a raw oil outlet of the layered series primary oil inlet heating furnace is connected with an oil-gas-water three-phase separator; an oil outlet of the oil-gas-water three-phase separator is connected with an oil transmission pump, a sewage oil-removing device and two heating furnaces; the sewage oil-removing device is connected with a water injection pump; and a layered series secondary oil well is sequentially connected with two oil inlet manifolds, a layered series secondary oil inlet heating furnace, an oil transmission pump and a mixed oil outer transmission heating furnace. The method has the effects of lower construction investment and convenience in production and operation, saves fuels of the heating furnaces, and is good for small block development of multilayered series overlapped development.
Description
technical field [0001] The present invention relates to the technical field of crude oil exploitation in oil and gas fields, and in particular to a ground gathering and transportation treatment process for multi-layer superimposed development of small-scale stations. Note, gathering and transportation processing method for pressurized crude oil export. Background technique [0002] At present, in view of the incompatibility of produced water, serious scaling and serious safety hazards in the ground gathering and transportation system in the superimposed development of multi-layer systems, single-layer system construction Production≤5×10 4 t / a, the proportion of incompatible strata is ≥20%, and a small dehydration, water treatment, and sewage reinjection system is newly built adjacent to the established station. In-place re-injection. Compared with the method of receiving oil from the well site at the pressurization point of single-layer system development, the water-conta...
