Background technique
Oily sludge is mainly derived from oil exploration, oil development, petroleum refining and crude storage and transportational process
In, comprising the big tank deposition bed mud of crude oil, the oily sludge of sewage treatment generation and due to originals such as sudden pollusion atmospheric events
Oily sludge etc. is landed because caused by, general oil content is high in sludge, has simultaneously containing a large amount of benzene homologues, phenols, pyrene, anthracene etc.
The noxious material of stench, large viscosity, Solid-Liquid Separation is difficult, and a large amount of not of the same race because using in oilfield treatments technical process
The water process such as a large amount of flocculating agents, corrosion inhibiter, fungicide and the antisludging agent added in the chemical treatment medicament and production process of class
Medicament, so that the bridge crosslinking structure in oil sludge and sand between each pollutant and inoganic solids is firm, constituent structure is more complicated,
The difficulty for objectively increasing treatment process, also increases processing cost.
Summary of the invention
The object of the present invention is to provide a kind of Downhole jetting devices of petroleum production system, can realize in oily sludge
The problem of three oil, water, mud separation, and safety and stability, high treating effect, operating cost are low.
To achieve the goals above, present invention employs technical solutions below: a kind of underground spray of petroleum production system
Injection device, including three separators, blender, liquidometer, temperature sensor, heating layers；It is equipped at the top of three separators
Dosing mouth and blender connect paddle, the dosing mouth external connection chemicals dosing plant on the agitating shaft of the blender；It is described
Three separator tops are equipped with oily sludge inlet port, oil outlet, and the oil outlet connects crude oil collection tank；The three phase separation
It is equipped with insulating layer circulating water intake in the middle part of device and outlet, supplement water and cleaning water inlet, the recirculated water come from heating equipment simultaneously
Heating layer is connected, the supplement water and ejected wash water are directly entered in the three phase separator；The three phase separator lower part is equipped with
Mud mouth and water outlet, the water outlet connect cesspool；The three phase separator side is equipped with liquidometer, and bottom is equipped with temperature
Sensor.
Wherein, heating coil is equipped in the insulating layer.
Wherein, the dosing mouth is equipped with automatic medicine adding apparatus, and dosage is realized according to flowmeter and automatically controlled.
Wherein, the water outlet is directly connected in cesspool, and sewage is further processed.
Wherein, the Downhole jetting device of a kind of petroleum production system, overall construction are divided into two layers inside and outside, outer layer
For heating layer.
The beneficial effects of the present invention are: oily sludge three-phase separating device of the invention, design rationally, solve oil-containing
In sludge the problem of oil, water, mud three phase separation, and safety and stability, high treating effect, operating cost are low, maximum throughput 8m3/
H, can be recycled in oily sludge 90% or more oil, and the oil content in oil recovery is 90% or more, the oil-containing in the water outlet of bottom
Rate is less than 1.5%, and oil content realizes minimizing, the recycling of oil-sludge treatment less than 0.3% in mud after processing；Oil-containing simultaneously
Sludge is avoided after treatment because of environmental pollution caused by outlet, is provided safeguard for the sustainable development in oil field, is had very
Good economic results in society.
