The basic procedure of 2 processing method of example and explanation(As shown in Figure 1, Figure 2, Figure 3 shows):
(1)Liquid phase flow process:
1)Normal plasma discharge:
①:7 → the first landwaste centrifuge for removing liquid 1-1 → the first slurry can 1-2 are sieved in drilling team's intrinsic vibration(It is high that liquid level is maintained at setting Between value and low value)→ the second landwaste centrifuge for removing liquid 1-4 → the second slurry can 1-3 → sand bits removing machine 3-1 → multi-functional regulation tank The agent-feeding treatment area of the sewage working area of 3-2 → multi-functional regulation tank 3-2 → water process regenerating device 3-7 → multi-functional regulation tank 3- 2 clear water working area → software 4 → reuse of clean water tank, when the first slurry can 1-2 is less than setting low value, control combination is met an urgent need storage tank 6 to first landwaste centrifuge for removing liquid 1-1 fluid infusion.
②:The intrinsic desander 8 of drilling team, 9 → the second landwaste centrifuge for removing liquid 1-4 → the second slurry can 1-3 of desilter → sand bits are removed Go the agent-feeding treatment area → water process regeneration of the sewage working area → multi-functional regulation tank 3-2 of machine 3-1 → multi-functional regulation tank 3-2 The clear water working area of machine 3-7 → multi-functional regulation tank 3-2 → software 4 → reuse of clean water tank
2)For slurry, meet an urgent need:Drilling team's intrinsic vibration is sieved into 7 first and is connected to the first slurry can 1-2.
7 → the first slurry can 1-2 are sieved in drilling team's intrinsic vibration, when the first slurry can 1-2 reaches setting high level → combined emergency 6 → the first landwaste centrifuge for removing liquid 1-1 → the first slurry can 1-2 → the second landwaste centrifuge for removing liquid 1-4 → the second slurry can 1-3 of storage tank → sand Agent-feeding treatment area → the water process of the sewage working area → multi-functional regulation tank 3-2 of bits removing machine 3-1 → multi-functional regulation tank 3-2 The clear water working area of regenerating device 3-7 → multi-functional regulation tank 3-2 → software 4 → reuse of clean water tank
In whole processing procedure, control the liquid level of the first slurry can and the second slurry can, make only the second slurry can to First slurry can overflow, and the first slurry can is not to the second slurry can overflow.
(2)Solid phase flow process:
①:First landwaste centrifuge for removing liquid 1-1 and the second landwaste centrifuge for removing liquid 1-4 → solid phase 2 → haulage vehicle of induction system
②:Intrinsic 10 → conveying worm of the centrifuge → haulage vehicle of drilling team
③:Husky bits removing machine 3-1 and water process regenerating device 3-7 → solid phase 2 → haulage vehicle of induction system
Process description:
The 7 liquid phase well drilling waste muds discharged, Jing are sieved by drilling team's intrinsic vibration that the first landwaste centrifuge for removing liquid 1-1 is collected After first landwaste centrifuge for removing liquid 1-1 carries out solid-liquid separation, liquid phase well drilling waste mud enters the first slurry can 1-2;First slurry can Liquid phase well drilling waste mud in 1-2 is come from the intrinsic desander 8 of drilling team, is desilted by the second landwaste centrifuge for removing liquid 1-4 is pumped into The liquid phase well drilling waste mud discharged by device 9 also into the second landwaste centrifuge for removing liquid 1-4, through the second landwaste centrifuge for removing liquid 1-4 solid-liquids After separation, liquid phase well drilling waste mud enters the second slurry can 1-3;Liquid phase well drilling waste mud in second slurry can 1-3 by Pump into and be extracted into husky bits removing machine 3-1, Jing after husky bits removing machine 3-1 carries out solid-liquid separation, liquid phase well drilling waste mud enters many work( Tank 3-2 can be adjusted, after infrequent menstruation amount dosing, stirring, water process regenerating device 3-7, Jing water process regenerating device 3-7 is pumped into by pump 3-5 After carrying out solid-liquid separation, the liquid phase of reuse standard is up to, is drained into the clear water working area of multi-functional regulation tank 3-2.According to existing Liquid phase in the multi-functional clear water working area for adjusting tank can be prepared medicines by practical situation, or can be by being pumped into out In software clean water tank 4, the liquid phase in software clean water tank 4 can be transmitted back to drilling team's mud system and carry out reuse, can also be kept in, etc. Treat subsequent treatment.
Solid phase well drilling waste mud Jing after the first landwaste centrifuge for removing liquid and the second landwaste centrifuge for removing liquid carry out solid-liquid separation, enters First order conveying worm, adds firming agent through firming agent addition machine 1-5, carries out conveying into second level conveying worm Mixing in journey, then, the drilling team received into third level conveying worm and third level conveying worm inherently from The solid phase well drilling waste mud given off by scheming 10, after carrying out the mixing in course of conveying, into fourth stage spiral transferring The solid phase drilling well waste sludge Jing after husky bits removing machine 3-1 carries out solid-liquid separation for sending machine to receive with fourth stage conveying worm Slurry, after carrying out the mixing in course of conveying, receives into level V conveying worm and level V conveying worm Solid phase well drilling waste mud Jing after water process regenerating device 3-7 carries out solid-liquid separation, after carrying out the mixing in course of conveying, It is transported to haulage vehicle 5 and waits subsequent treatment.
Example two is, using a kind of overall coherent processing equipment, to be easy to control when processing relative to the difference of example one System.Example two when using the data essentially identical with table 1-3 can reach the effect essentially identical with example one, but can shorten operation Time, reduce the workload of workman.
What each separation equipment is isolated in this patent density was larger is referred to as solid phase, and density is less to be referred to as liquid phase, and this is specially In profit, alleged solid phase is not absolute solid phase, and liquid phase is nor absolute liquid phase, such as water process regenerating device 14 is separated It is also likely to be moist soil or the sludge for having certain fluidity to go out solid phase.
