The invention discloses a discrete
layout movable
steam injection device and a
steam injection process thereof. The discrete
layout movable
steam injection device are used for steam injection of a plurality of
oil production wellheads distributed in each area of an
oil field, and the multiple
oil production wellheads communicate to an underground oil layer through a Christmas tree and an underground oil
pipe. The discrete
layout movable steam
injection device comprises a movable boiler, a movable pipeline, a plurality of steam thin pipelines, a plurality of water,
electricity and gas stations and water,
electricity and gas thin pipelines, wherein one end of the movable pipeline can be quickly and detachably connected with the movable boiler; one end of each steam thin pipeline is connected with one
oil production wellhead, and the other end of each steam thin pipeline can be quickly and detachably connected with the other end of the movable pipeline; the multiple water,
electricity and gas stations are distributed in all areas of the
oil field, and each water, electricity and gas
station comprises a water interface, an electricity interface and a gas interface at fixed positions; the water, electricity and gas thin pipelines are arranged at all the water, electricity and gas stations, and the movable boiler is connected with water, electricity and gas interfaces at the fixed positions of the water, electricity and gas stations through the water, electricity and gas thin pipelines. Nearby steam injection can be achieved, the length of a steam injection pipeline is shortened, and heat loss is reduced.
