Abstract
The invention discloses a water-controlling valve for oil extraction, which comprises a nozzle device and a plug device that are symmetrically arranged on the tube wall of a base tube. The nozzle device comprises a base, a nozzle and a press cap; the plug device comprises a base, a plug and a press cap. The base is hollow and is arranged on the base tube; both the nozzle and the plug are composite slice materials of polycrystalline diamond and are fixed on the base; the press cap is covered on the nozzle and the plug and is spirally connected with a supporting ring. The technical proposal provided by the water-controlling valve for oil extraction has the beneficial effect of controlling the water flow during the process of oil extraction, thereby improving the oil-extraction efficiency in the oil field and reducing the loss of manpower and material resources.
Description
Technical field
The present invention relates to extracting device of oil, particularly a kind of water controlling valve for oil extraction.
Background technology
It is by the pump housing crude oil to be evacuated to ground that underground crude oil is extracted in the oil field, because impurity such as tar sands, wax and dirt in the crude oil work long hours and can stop up the pump housing.The anti-sandpipe that generally adopt in present oil field mainly contains two kinds of structures: one is made of outer pillar and parent tube.Outer pillar, parent tube are cylindrical body, and outer pillar is arranged at outside the parent tube.The tube wall of outer pillar is provided with aperture, plays the effect of filter sand.Its two, anti-sandpipe is made of outer pillar, filter sand net, internal protective cover, parent tube, successively tubular structure from outside to inside.Outer pillar plays the protective device effect, and the filter sand net can filter out the sand grains in the crude oil, and internal protective cover plays the effect of supporting the filter sand net, even distribution aperture on the parent tube.Connect flow string at parent tube one end, crude oil is through filtration like this, enters in the crude oil of the pump housing sand grains by filtering.When meeting a large amount of water in the oil recovery process, need the flow of control water, reduce the cost that recovers the oil.The present invention increases water controlling valve for oil extraction in the anti-sandpipe of second kind of structure, effectively control the flow of water in the oil recovery process.
Summary of the invention
The objective of the invention is to, the flow of W/O is adopted in control, improves the crude oil output quality.
To achieve these goals, the invention provides a kind of water controlling valve for oil extraction, comprise spray nozzle device, plug device, on the tube wall that is arranged on parent tube of its symmetry; Spray nozzle device comprises base, nozzle and pressure cap; The plug device comprises base, plug and pressure cap.
A kind of water controlling valve for oil extraction, described base hollow is arranged on the parent tube; Nozzle and plug are the composite polycrystal-diamond material, are fastened on the base, and base is a metal material; Pressure cap covers on it, is connected with the support ring spiral.
The beneficial effect of technical scheme provided by the invention is: the flow of water in the control oil recovery process, thus improve the oil recovery efficiency in oil field, reduce the manpower loss.
Description of drawings
Fig. 1 is a water controlling valve for oil extraction cross-sectional structure schematic diagram of the present invention.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Fig. 1 is a water controlling valve for oil extraction cross-sectional structure schematic diagram of the present invention.The invention provides a kind of water controlling valve for oil extraction, comprise spray nozzle device, plug device, the tube wall two ends that are arranged on parent tube 1 of symmetry.Spray nozzle device comprises base 2, nozzle 3 and pressure cap 4; The plug device comprises base 2, plug 5 and pressure cap 4.Base 2 hollows are arranged on the parent tube 1; Nozzle 3 and plug 5 are the composite polycrystal-diamond material, are fastened on the base 2; Pressure cap 4 covers on it, is connected with support ring 6 spirals.
Anti-sandpipe of the present invention is made of outer pillar, filter sand net, internal protective cover, parent tube 1, successively tubular structure from outside to inside.Outer pillar plays the protective device effect; the filter sand net can filter out the sand grains in the crude oil, and internal protective cover plays the effect of supporting the filter sand net, and the interval property is provided with water-control valve on the parent tube 1; oil water mixture flows into parent tube 1 by water-control valve, has reduced the water content in the crude oil in a large number.At parent tube one end the oil transportation hole is arranged, the oil transportation hole connects the pump housing, and crude oil is through filtration like this, enters in the crude oil of the pump housing sand grains and has controlled the wherein flow of water simultaneously by basic filtering.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
