Description
Technical field
The utility model relates to a kind of retracting device of drilling fluid.
Background technology
At present, domestic land drilling well industry and marine drilling industry all do not realize the recycle of drilling fluid, and this is a kind of more serious waste for resource, also can cause certain destruction to environment.Abroad, it is that single spiral filtration formula centrifuge is realized solid controlling that the marine drilling aspect is used more at present, and what land drilling well industry use was more is single screw settling formula centrifuge, and they can realize the utilization again of drilling fluid to a certain extent.But because the unicity of systemic-function, its application receives the bigger restriction of situation such as mother liquid concentration, solid particle size, so the effect of solid controlling and efficient are not very good.
The utility model content
The utility model technical problem to be solved is: the retracting device that a kind of drilling fluid of the drilling fluid Separation of Solid and Liquid that satisfies variable concentrations and granular size is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of retracting device of drilling fluid; Comprise first reversal valve, vibrosieve, second reversal valve, filtering centrifuge, sedimentation centrifuge, first collecting tank and Teat pipette; Three outlets of first reversal valve link to each other with vibrosieve inlet, the inlet of second reversal valve and the inlet of sedimentation centrifuge respectively; The outlet of vibrosieve also links to each other with the inlet of second reversal valve, and two outlets of second reversal valve link to each other with the inlet of filtering centrifuge and the inlet of sedimentation centrifuge respectively, and the outlet of filtering centrifuge also links to each other with the inlet of sedimentation centrifuge; The outlet of sedimentation centrifuge links to each other with first collecting tank, and Teat pipette links to each other with first collecting tank.
Be connected with second collecting tank and screw pump between said filtering centrifuge and the sedimentation centrifuge in turn, one of them outlet of second reversal valve links to each other with second collecting tank.
In said first collecting tank agitator is set.
The beneficial effect of the utility model is: after having comprised vibrosieve, filtering centrifuge and sedimentation centrifuge; Difference according to mud solid phase concentration; The drilling well that utilizes reversal valve to make is reclaimed liquid and is carried out Separation of Solid and Liquid through different separation equipments, has satisfied the recovery requirement that liquid is reclaimed in multiple concentration drilling well.

Among the figure: 1, first reversal valve, 2, vibrosieve, 3, second reversal valve, 4, filtering centrifuge, 5, sedimentation centrifuge, 6, first collecting tank, 7, Teat pipette, 8, second collecting tank, 9, screw pump, 10, agitator.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 1; The retracting device of the described drilling fluid of the utility model; Comprise first reversal valve 1, vibrosieve 2, second reversal valve 3, filtering centrifuge 4, sedimentation centrifuge 5, first collecting tank 6 and Teat pipette 7; Three outlets of first reversal valve 1 link to each other with vibrosieve 2 inlets, the inlet of second reversal valve 3 and the inlet of sedimentation centrifuge 5 respectively; The outlet of vibrosieve 2 also links to each other with the inlet of second reversal valve 3, and two outlets of second reversal valve 3 link to each other with the inlet of filtering centrifuge 4 and the inlet of sedimentation centrifuge 5 respectively, and the outlet of filtering centrifuge 4 also links to each other with the inlet of sedimentation centrifuge 5; The outlet of sedimentation centrifuge 5 links to each other with first collecting tank 6, and Teat pipette 7 links to each other with first collecting tank 6.In order to make suitable the connecing of production capacity between filtering centrifuge 4 and the sedimentation centrifuge 5, one of them outlet that is connected with second collecting tank 8 and screw pump 9, the second reversal valves 3 between filtering centrifuge 4 and the sedimentation centrifuge 5 in turn links to each other with second collecting tank 8.For drilling fluid and additive in first collecting tank 6 mix, in first collecting tank 6, agitator is set.
The course of work of the utility model is: owing to the difference along with drilling depth; Wherein the concentration of contained solid phase also can be different after drilling fluid used; Be roughly: it is the highest and contain a large amount of oarse-grained solid phases to be positioned near the face of land solid concentration; More past underground, the particle of solid phase is more little and concentration is low more.So; If reclaiming in the liquid, drilling well contains bulky grain, middle particle, granule solid phase; Drilling well is reclaimed liquid and is just arranged like the recover route: first reversal valve, 1 → vibrosieve, 2 → the second reversal valves, 3 → filtering centrifuge, 4 → the second collecting tanks, 8 → screw pump, 9 → sedimentation centrifuge, 5 → the first collecting tanks 6; Utilize Teat pipette 7 will in first collecting tank 6, add the additive of according with process requirements at last, and stir through agitator 10 and to get final product, the drilling fluid that is produced just can utilize again.If reclaiming in the liquid, drilling well contains middle particle, short grained solid phase; Drilling well is reclaimed liquid and is just arranged like the recover route: first reversal valve, 1 → the second reversal valve, 3 → filtering centrifuge, 4 → the second collecting tanks, 8 → screw pump, 9 → sedimentation centrifuge, 5 → the first collecting tanks 6; Utilize Teat pipette 7 will in first collecting tank 6, add the additive of according with process requirements at last; And stir through agitator 10 and to get final product, the drilling fluid that is produced just can utilize again.If reclaiming in the liquid, drilling well only contains short grained solid phase; Drilling well is reclaimed liquid and is just arranged like the recover route: first reversal valve, 1 → sedimentation centrifuge, 5 → the first collecting tanks 6; Utilize Teat pipette 7 will in first collecting tank 6, add the additive of according with process requirements at last; And stir through agitator 10 and to get final product, the drilling fluid that is produced just can utilize again.If drilling well is reclaimed liquid behind vibrosieve 2, only contained the granule solid phase, can walk around filtering centrifuge 4 so, promptly second reversal valve 3 directly communicates with second collecting tank 8.The drilling fluid retracting device of said structure can be regulated and reclaim route according to the size of solid phase particles at any time, satisfies various different demands, has improved production efficiency.
