Technical field
The utility model is related to waste drilling thing process field, is a kind of quick separation of solid and liquid of oilfield drilling waste
Device.
Background technology
Needed in oilfield drilling production after circulating fluid, a bite well be drilled to, drilling cuttings and discarded slurry amount are very big.These
Some inorganic salts, heavy metal components, oil product and substantial amounts of organic polymer in drilling wastes etc. have larger danger to environment
Evil, substantially exceeds the discharge standard of national regulation.It is dirty if not handled these discarded objects and being deposited in well site or burial
Dye thing can flow into farmland, river, ocean, and heavy damage, pollution drinking-water water source, influence soil and animals and plants life are produced to environment
It is long, or even jeopardize human health.
Oilfield drilling waste composition is complicated, containing a large amount of fine particles, and viscosity is big, and liquid holdup is high, is petroleum gas
One of primary pollution source of industry, its harmless treatment is the problem of current puzzlement oil drilling production.
At present, oil field at home mainly sets mud pit, finishing drilling for the processing mode of drilling wastes in situ of drilling well
Curing agent is added in backward mud pit and carries out curing process, is then filled on the spot.This processing method floor space is big, antiseepage
Pond, mud pit are built and maintenance cost is high, and discarded object needs to deposit longer time at the scene, are influenceed very big by weather condition,
And there is soak in the extension of solidfied material over time, be also easy to produce secondary environmental pollution.
Because the requirement that environmental protection policy is discharged to drilling wastes is more and more stricter, in drilling well fast drilling at initial stage, drilling cuttings
The like waste yield is big, and mud is containing height, and discarded object dehydration difficulty is big, has become the bottle that restriction oil drilling drilling cuttings is handled online
Neck.A set of practicable treatment technology is developed, preliminary treatment is carried out to drilling wastes in scene, is then carried out again follow-up
Focus on, reduce environmental pollution, be the task of top priority of China's drilling well industry environment protection work.
Utility model content
The utility model aims to solve the problem that above-mentioned technical problem, and there is provided a kind of quick separation of solid and liquid dress of oilfield drilling waste
Put, preliminary treatment is carried out to drilling wastes in situ of drilling well, the desiccation and minimizing of wet drilling bit is realized, be its solidification and resource
Change using condition is provided, the liquid after processing can recycle or send sewage plant to be further processed.Its technical side used
Case is as follows：
A kind of quick equipment for separating liquid from solid of oilfield drilling waste, it is characterised in that：Including surge tank, sludge pump, self-cleaning
Formula filter centrifugal, high speed horizontal-spiral centrifuge, conveying worm and drilling cuttings drier；Surge tank by sludge pump and self-cleaning from
Heart filtering machine inlet connection, self-cleaning centrifugal filter leakage fluid dram is connected with high speed horizontal-spiral centrifuge, self-cleaning centrifugal filtering
Machine slag-drip opening and the outlet of high speed horizontal-spiral centrifuge concentrated phase connect drilling cuttings by conveying worm and dry machine inlet, and drilling cuttings is dried
Machine leakage fluid dram is connected with surge tank.
The surge tank top connects surge tank medicament dispenser pump, inside installing buffering jar agitator.
The utility model has advantages below：Based on mechanically decoupled, it is aided with active agents, overcomes drilling well in mud pit
The slow-footed shortcoming of discarded object natural evaporation, is not influenceed by weather condition；And system is reliable and stable, continuously-running, operation
Simply, operating cost is low, and condition is provided for the effective, harmlessization processing of oilfield drilling waste.
Brief description of the drawings
Fig. 1 is the quick equipment for separating liquid from solid schematic diagram of oilfield drilling waste proposed according to the utility model.
As shown in figure 1,1 is surge tank, 2 be self-cleaning centrifugal filter, 3 is high speed horizontal-spiral centrifuge, 4 is helical feed
Machine, 5 be drilling cuttings drier, and 6 be sludge pump, and 1.1 be surge tank medicament dispenser pump, and 1.2 be buffering jar agitator, and 2.1 be self-cleaning
Formula centrifugal filtration machine inlet, 2.2 be self-cleaning centrifugal filter leakage fluid dram, and 2.3 be self-cleaning centrifugal filter slag-drip opening,
3.1 be the outlet of high speed horizontal-spiral centrifuge concentrated phase, and 5.1 be that drilling cuttings dries machine inlet, and 5.2 be drilling cuttings drier leakage fluid dram.
Embodiment
The utility model is further described with example below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of quick equipment for separating liquid from solid of oilfield drilling waste, including it is surge tank 1, sludge pump 6, self-cleaning
Formula filter centrifugal 2, high speed horizontal-spiral centrifuge 3, conveying worm 4 and drilling cuttings drier 5；Surge tank 1 is by sludge pump 6 and certainly
Clean formula centrifugal filtration machine inlet 2.1 is connected, and self-cleaning centrifugal filter leakage fluid dram 2.2 is connected with high speed horizontal-spiral centrifuge 3, from
Clean formula filter centrifugal slag-drip opening 2.3 and high speed horizontal-spiral centrifuge concentrated phase outlet 3.1 connect drilling cuttings by conveying worm 4 and got rid of
Dry machine inlet 5.1, drilling cuttings drier leakage fluid dram 5.2 is connected with surge tank 1.
