Abstract

The invention discloses a multi-layer water mixing and injection descaling device. The device is characterized in that a first deoiling tank, a second deoiling tank, a third deoiling tank and a fourth deoiling tank are connected with independent metering pumps respectively; each metering pump is connected with a mixer; the mixer, a scale-borer, a reactor, a flocculating settling tank, a primary filter, a secondary filter and a water injection pump are sequentially connected; a water inlet end connection pipe of the reactor is connected with a dosing device; the reactor and the flocculating settling tank are connected with a sludge tank respectively; and the primary filter and the secondary filter are connected with a water inlet end connection pipe of the mixer respectively. The device disclosed by the invention has the beneficial effects that the treatment process of the oily sewage recovered on the same layer is easy to operate, the treatment capacity is large and the requirements on the scaling quantity and reservoir protection in water reinjection after treatment are met.

Description

Technical field [0001] The invention belongs to the technical field of equipment manufacturing equipment, and relates to a multi-layer water mixed injection descaling device. Background technique [0002] Oilfield produced water treatment is an important part of water injection development. Various oil production plants in the North Shaanxi Oilfield have problems in the development of multi-layered systems of varying degrees. For example, the development layers include the Jurassic Yan’an Formation Yan 6, Yan 7, Yan 8, Yan 9, Yan 10, Fuxian Formation, Triassic Yanchang Formation Chang1, Chang2, Chang3, Chang4+5, Chang6, Chang7, Chang8, Chang9, Chang10, the water injection horizons are mainly Jurassic Yan'an Formation Yan9, Yan10, Fuxian Formation, 3 The superimposed extension group has length 2, length 4+5, length 6, length 7, length 8, and length 9. Due to the large differences in the properties of the produced water from different layers, the sewage with poor compatibility wi...
