Description
Technical field
The present invention relates to a kind of packaged type flushing fluid purifying processing devices, belong to oil field flushing liquid processing device technology neck
Domain.
Background technology
In Sand-washing in Oilfield clean-out service research work, since hydraulic sand washing is simple for process, bottom-hole cleaning is complete, and has
There is the characteristics of sand washing amount is big to be used widely.This method is to give sand cleaning fluid higher flowing velocity by pump truck, this is allowed to flow
It moves quick sand cleaning fluid to inject into well, the sand grains in well is broken up using hydraulic action, then when liquid stream returns producing well, shaft bottom quilt
The sand grains broken up is carried over oil well using the carrying capacity of liquid, so that the process that well inner product sand is removed.Early stage
In sand-flushing operation, since gravity settling technology is simple in structure, and sand cleaning fluid can be repeatedly circulated and in oil field
It is used widely.I.e. well-washing truck injects into well the sand cleaning fluid in circulatory pool, and when being returned on sand cleaning fluid, the impurity such as silt particle are straight in well
It connects and is carried into circulatory pool, the mixing sand-flushing liquid in circulatory pool causes solid to be detached with liquid by gravity, sand grains
Solid particles is waited gradually to be settled down to buffering pot bottom, the sand cleaning fluid after separation of solid and liquid, which can be re-injected in well, to be recycled.
But the shortcomings that this technology is also obvious：1. sand washing is incomplete in well.As what sand-flushing liquid recycled increases,
The impurity booty content wherein contained also can be more and more, and when more than certain limit, the ability that sand cleaning fluid carries sand grains can be by
The phenomenon that gradually reducing, the sand grains that shaft bottom is broken up is caused still to be left on shaft bottom；2. sand cleaning fluid purification cycle is long.Because sand grains and punching
The separation of sand liquid is by natural subsidence, and sand cleaning fluid can not spread out from mixing sand-flushing liquid in a short time, so as to prolong
Entire Sand-washing cycle is grown；3. live sand removal is difficult, labor intensity is big.The solid particles such as the sand grains settled in circulatory pool need fixed
Phase carries out manual cleaning, increases the consumption of personnel and goods and materials, and working environment is poor, accident easily occurs；4. waste water resource.
In order to improve the separative efficiency of circulatory pool, frequent clean cycle pond；5. pollute environment.Process in artificial clean cycle pond
In, since sundries is more in circulatory pool, once discharge, necessarily causes the pollution of environment.So study a kind of well-flushing sand cleaning fluid point
Seem most important from purifier.
Invention content
Present invention mainly solves the technical issues of：Long for prior art sand cleaning fluid purification cycle, sand removal is difficult, and labour is strong
The problem of spending big, waste water resource, be easy to causeing environmental pollution, the present invention provides a kind of packaged type flushing fluid purified treatments
Device.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of packaged type flushing fluid purifying processing device, including rack, the rack is drawn by tractor, is above rack
Flushing fluid purifying processing device, flushing fluid purifying processing device inside left are provided with settling tank, mud are provided with above settling tank
Sand pump and flushing fluid inlet duct, settling tank lower left are sediment pump and silt outlet conduit, are provided on the right side of settling tank
Fuel reserve tank, fuel reserve tank are connected by oil-absorbing pipeline with settling tank, and oil scavenge pump is provided in pipeline, are cyclone separator on the right side of fuel reserve tank
It is connected by pipeline with settling tank, cyclone separator is connected by pipeline with atomising device, is detached below atomising device for coarse grain
Device, coarse grain separator are internally provided with coarse grain layer.
A kind of application process of packaged type flushing fluid purifying processing device is：By sediment pump by flushing fluid from flushing fluid
Inlet duct is pumped into settling tank, and after settling tank internal precipitate, oil, water and silt layering inside flushing fluid pass through oil scavenge pump
The grease of one layer of the top is sucked into fuel reserve tank with oil-absorbing pipeline, the silt that one layer of bottom is through sediment pump and silt delivery pipe
Road is discharged, and flushing fluid after precipitation enters cyclone separator, and silt and grease remaining in flushing fluid, separation are removed by cyclone separator
Flushing fluid afterwards is injected into coarse grain separator after atomising device is atomized, and using grease, to solid matter, affine situation is not
With when oil water mixture flows through haydite layer, being forced constantly to change flow velocity and direction, the collision coalescence probability of water droplet is increased, is made
Droplet rapid coalescence settles, and so as to remove the grease dissolved in flushing fluid, completes the purification of flushing fluid.
The oil-absorbing pipeline extend into oil layer in settling tank, convenient for adsorbing grease.
It is connected between the atomising device and coarse grain separator using injection apparatus.
The material that the coarse grain filter layer uses is ceramic coarse grain.
The beneficial effects of the invention are as follows：
（1）Deficiency devises a kind of flushing fluid purifier to the present invention according to prior art, and Multistage purifying is employed in the present invention
Flushing fluid is carried out layered shaping by the mode of change using the precipitation method first, and the fluid and lowest level of top layer are removed after layering
Silt, obtain the flushing fluid of preliminary purification, then the suspended particulate substance and silt in flushing fluid are removed by cyclone separator, then make
Flushing fluid is atomized with atomising device and removes the dissolved matter in flushing fluid through coarse grain separator so as to complete the purification of flushing fluid,
The coarse grain separator used in the past is to be evaporated flushing fluid, then affine to solid matter using grease by coarse grain layer
The difference of situation is forced constantly to change flow velocity and direction, the collision for increasing water droplet gathers when oil water mixture flows through haydite layer
Probability is tied, settles droplet rapid coalescence, so as to remove the grease dissolved in flushing fluid, but flushing fluid evaporation is needed largely
Energy, movable type well-flushing liquid purifier is not suitable for, so the present invention is using atomising device, compared to evaporation well-flushing liquid mist
More energy saving and purification efficiency higher is put in makeup.
（2）Washing water need to be transported to purifying station by previous flushing fluid purifier all using fixed using transport vehicle
Flushing fluid is purified, not only well-flushing efficiency is low in this way, and the time is long, it is also necessary to consume more energy, the present invention uses tractor
The flushing fluid purifier of packaged type is drawn, the purification of flushing fluid can be completed by oil well, improves the efficiency of well-flushing, is saved
About cost.
