Abstract
The utility model relates to a pressure-regulating water-controlling sand control pipe, belonging to the field of tools for extracting oil, water and gas from an oil well and comprising a unit internal structure pipe, wherein the unit internal structure pipe is provided with a skeleton layer, a filter layer and an outer protective pipe from inside to outside in sequence, more than two pressure regulating controllers are arranged at the outer side of the unit internal structure pipe respectively, the outer ends of the pressure regulating controllers extend out of the outer protective pipe, and the inner sides of the pressure regulating controllers are connected with a flow-adjustable nozzle inside an oil collecting cavity. The pressure-regulating water-controlling sand control pipe has the advantages that flow adjustment can be realized based on different stratigraphic configurations, thus bottom water coning can be delayed and controlled and oil extraction and sand control can be effectively carried out. The pressure-regulating water-controlling sand control pipe has a superior effect in the recovery of oil wells with high water content and oil wells which stop oil production owing to high water, the oil production from old wells and the control for the yield of oil wells with high water content, brings direct economical and social benefits.
Description
Technical field
The utility model relates to the anti-sandpipe of a kind of pressure regulation control water, belongs to the field of tool of getting Oil, Water, Gas from oil well.
Background technology
In oil fields such as NORTHWEST CHINA, Ji Dong, huge port, triumph, Jiang-Han Area, stratum sand content height, when extracting, tend to take place the problem of gravel blocking pipe, simultaneously, in recovery process, the serious water outlet that causes because of bottom water coning has caused a large amount of oil fields to stop well, and only Sinopec just reaches more than 159 mouthfuls of wells.In the horizontal well production technology of crude oil, because of water outlet has to some extent become influence and restricted the horizontal well crude oil production.
At present, also not having in oil mining can be by regulating in the pipeline flow to change exploitation pressure, delays and controls bottom water coning, again the effective exploitation instrument of sand control.Therefore, be badly in need of a kind of exploitation instrument that can change the problems referred to above, to solve the deficiencies in the prior art.
The utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of pressure regulation control water to prevent sandpipe, can carry out in the pipeline Flow-rate adjustment to change exploitation pressure according to the Different Strata structure, delay and control bottom water coning, sand control effectively can recover the oil again.
Pressure regulation control water described in the utility model is prevented sandpipe; comprise unit inner structure pipe; be disposed with casing play, filtration beds, outer protection tube on the unit inner structure pipe from inside to outside; the inner structure pipe outside, unit is provided with two above voltage regulator controllers respectively; the outside that reaches outer protection tube is visited in this voltage regulator controllers outer end, and voltage regulator controllers adjustable flow nozzle inboard and in the collection chamber is connected.
Wherein, be coaxially installed with box cupling and spiral centralizer on the unit inner structure pipe, be provided with and the center line uniform long slot bore in a plurality of intervals in the same way on the described outer protection tube; The two ends of unit inner structure pipe are provided with screw thread, in order to the connection between the adjacent cells inner structure pipe; Filtration beds adopts multilayer stainless steel screen pack combining structure; Each voltage regulator controllers links with adjustable flow nozzle more than 12 respectively.
In addition, outer protection tube links to each other with end ring on the unit inner structure pipe, increases its stability.
During work; the anti-sandpipe of pressure regulation control water is kept flat oil-feed layer place; oil, underground water or the natural gas that contains grit enters by the long slot bore of outer protection tube; through after the filtration of filtration beds; prolong axially from the gap between casing play and the filtration beds and to be transported in the collection chamber by nozzle; thereby enter in the unit inner structure pipe, extract out at last.The difference of base area stressor layer, the number of opening that changes collection chamber is reconciled pressure, to reach the purpose of control bottom water coning.
The beneficial effect that the utility model had is: can carry out Flow-rate adjustment according to the Different Strata structure, promptly can delay and control bottom water coning, sand control effectively can recover the oil again.The recovery of the oil well that it stops production to high-water-cut oil-producing well, because of high water, the exploitation of old well, control water content high oil well yield can play good effect, and direct economic benefit and social benefit are arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged drawing of I among Fig. 1;
Wherein, 1, box cupling 2, spiral centralizer 3, collection chamber 4, unit inner structure pipe 5, end ring 6, outer protection tube 7, filtration beds 8, casing play 9, voltage regulator controllers.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As depicted in figs. 1 and 2; box cupling 1 and spiral centralizer 2 coaxial being installed on the unit inner structure pipe 4; be disposed with casing play 8, filtration beds 7 and outer protection tube 6 on the unit inner structure pipe 4 from inside to outside; 2 voltage regulator controllers 9 are set on the unit inner structure pipe 4, and the adjustable flow nozzle in voltage regulator controllers 9 and the collection chamber 3 is connected.
Be provided with and the center line uniform long slot bore in a plurality of intervals in the same way on the outer protection tube 6; The two ends of unit inner structure pipe 4 are provided with screw thread, in order to the connection between the adjacent cells inner structure pipe 4; Filtration beds 7 adopts multilayer stainless steel screen pack combining structure.
In addition, outer protection tube 6 links to each other with end ring 5 on the unit inner structure pipe 4, increases its stability.
During work; the anti-sandpipe of pressure regulation control water is kept flat oil-feed layer place; oil, underground water or the natural gas that contains sand grains enters by the long slot bore of outer protection tube 6; through after the filtration of filtration beds 7; prolong axially from the gap between casing play 8 and the filtration beds 7 and to be transported in the collection chamber 3 by nozzle; thereby enter in the unit inner structure pipe 4, extract out at last.The difference of base area stressor layer, the number of opening that changes nozzle is reconciled pressure, to reach the purpose of control bottom water coning.
The utility model can carry out Flow-rate adjustment according to the Different Strata structure, promptly can delay and control bottom water coning, and sand control effectively can recover the oil again.The recovery of the oil well that it stops production to high-water-cut oil-producing well, because of high water, the exploitation of old well, control water content high oil well yield can play good effect, and direct economic benefit and social benefit are arranged.
