Accompanying drawing explanation
Figure 1 shows that the structure chart of the utility model based on the gas drilling cuttings disposal system of rotational flow separation.
Detailed description of the invention
Hereafter will describe the utility model specific embodiment in detail in conjunction with concrete accompanying drawing.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.
As shown in Figure 1, the utility model provides a kind of gas drilling cuttings disposal system based on rotational flow separation, comprising: cyclone separator 1, cleaner 2, first water tank 3, second water tank 4, three-tank 5, centrifugal pump 8 and anti-overflow exhaust pipe 9; Several identical cyclone separators 1 are also unified into cyclone separator group, and each cyclone separator 1 is provided with an air inlet port 10, for importing drilling well gas; Cyclone separator 1 is also provided with a charging aperture, and is connected with centrifugal pump 8 water side by band valve pipeline; Cyclone separator 1 underflow opening is all by connecing cleaner 2 under pipeline, cyclone separator 1 top overfall connects three-tank 5 by band valve pipeline; Three-tank 5 top is provided with anti-overflow exhaust pipe 9; Three-tank 5 is connected with the second water tank 4 by the second automatic control of liquid one way valve 7; Centrifugal pump 8 water inlet connects the second water tank 4 outfall; Second water tank 4 is connected with the first water tank 3 by the first automatic control of liquid one way valve 6; Cleaner 2 connects the first water tank 3 top.
Further, cyclone separator 1 is antisymmetry bidirectional feed, one of them charging aperture air inlet body, a charging aperture feed liquor body.
Further, screen pack anti-overflow device 12 is provided with in anti-overflow exhaust pipe 9.
Further, cyclone separator 1 and cleaner 2 are installed in above the first water tank 3, second water tank 4 and three-tank 5, achieve skid.
Operating principle:
The drilling well gas of the cutting carring that annular space returns out enters the some cyclone separators 1 be installed in parallel from air inlet port, the number of the cyclone separator 1 opened can control according to well head actual flow, water in second water tank 4 another charging aperture through cyclone separator 1 pumps into by centrifugal pump 8 simultaneously, realize solid, liquid, gas three-phase fully mixes at cyclone separator 1, under the effect of the inner centrifugal force of cyclone separator 1, the solid that density is large and most water form the liquid slurry of fluidised form, discharge with the underflow opening of the form of contour stealth from cyclone separator 1, the gas that density is little then forms inward eddy in cyclone separator 1 inside and discharges with the overfall of the form of overflow from cyclone separator 1 top, thus carried out gas, Gu be separated, the fluidised form liquid slurry of discharging from underflow opening still contains a certain amount of water, directly guide to cleaner 2 through header to be separated, cleaner 2 isolates landwaste in the fluid-mixing of landwaste and water and water, and isolated landwaste is derived from sand outlet 11 and transported by workman, and water is got back in the first water tank 3 by pipeline, the fluid of being discharged by overfall (most gas and few partially liq and solid) is incorporated into below the liquid level of three-tank 5 after header collects, and stays gas in water through gas washing discharge carrying a small amount of water and landwaste in gas through anti-overflow exhaust pipe 9, the water be separated through cleaner 2 still contains a small amount of fine particle, and collect in the first water tank 3, natural subsidence in the first water tank 3, when the liquid level of the first water tank 3 reaches the liquid level higher than the second water tank 4, first automatic control of liquid one way valve 6 is opened, water then in the first water tank 3 flows in the second water tank 4 automatically, when the liquid level of three-tank 5 reaches the liquid level higher than the second water tank 4, second automatic control of liquid one way valve 7 is opened, water then in three-tank 5 flows in the second water tank 4 automatically, thus achieves recycling of water, also can be provided with back purge system bottom first water tank 3, when bottom sink mud more be can human at periodic intervals cleaning.
If enough for the drilling well gas pressure carrying landwaste returned out from annular space, directly pass into cyclone separator 1 and be separated, be separated if pressure, needs to pass into cyclone separator 1 more not after pressurized equipment pressurization.
What the utility model provided is a kind ofly all connected with the second water tank based on the first water tank, three-tank in the gas drilling cuttings disposal system of rotational flow separation, and achieve recycling of water resource, the well site far away in some dried up sources is very practical.Effectively can be separated the landwaste in drilling well gas, improve the air quality in well site during gas drilling operation greatly, saving water resource can reclaim and recycle by the gas drilling medium higher to cost simultaneously.And each water tank is arranged on same base side by side, separator and cleaner are arranged on water tank, achieve skid, have compact conformation, floor space, movement advantage easily.
Although given embodiments more of the present utility model, it will be understood by those of skill in the art that when not departing from the utility model spirit herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of the utility model interest field.
