Abstract
The invention belongs to the field of an oil recovery underground sand preventing tool, in particular relates to an earthworm sand filter sieve tube. The earthworm sand filter sieve tube comprises a tube main body, wherein an SGP filter layer is arranged on the outer circumference of the tube main body, an outer spiral protection tube is arranged outside the SGP filter layer, two ends of the outer spiral protection tube are respectively provided with an end ring, two ends of the tube main body are respectively provided with a connecting hoop, the SGP filter layer comprises transverse filaments and longitudinal filaments, and the transverse filaments and the longitudinal filaments are arranged in an intersecting manner. The earthworm sand filter sieve tube is used for exploiting bottom water reservoir and has a good effect for restoring an oil well with high water content and an oil well which is stopped due to the high water content, exploiting an old well and controlling the yield of the oil recovery well with high water content.
Description
Technical field
The present invention relates to a kind of earthworm sand-screen, belong to oil recovery down-hole sand-proof tool field.
Background technology
The existing traditional sand-screen of current oil field at home is of a great variety, but the sand-screen of blockage problem is not also solved accordingly at bad ground oil reservoir, especially the later stage in oil field recovers the oil, traditional sand-screen can not meet Production requirement, sand controlling result is poor, life-span is short, becomes the Main Bottleneck of the recovery ratio of impact and restriction crude oil.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and effectively can improve again recovery ratio, three-dimensional filtration, de-plugging automatically by sand control in bad ground oil extraction in oil field, fundamentally solve the earthworm sand-screen of oil field later stage exploitation sand control.
Earthworm sand-screen of the present invention; comprise tube body; tube body periphery arranges SGP filtration beds; spiral outside protective pipe is set outside SGP filtration beds; the two ends of spiral outside protective pipe arrange end ring; tube body two ends arrange box cupling, and SGP filtration beds comprises transverse fiber silk and longitudinal fiber silk, and transverse fiber silk and the square crossing of longitudinal fiber silk are arranged.
Spiral outside protective pipe mainly protects inner SGP filtration beds, and SGP filtration beds adopts multilayer stainless steel filter screen, the filtering accuracy after combination can meet oil, gas or water precision prescribed, realize the effect of filter sand.Tube body is mainly born main framing and is connected the main body of oil, gas or water.Sand screen can be formed by connecting by many tube bodies, and every root tube body two ends arrange screw thread respectively.
In described SGP filtration beds every transverse fiber silk and longitudinal fiber silk respectively using 3 as between the upper and lower every, above 33 below, in 3 fibres, both sides is stainless steel fiber, and centre is carbon fiber wire.The carbon fiber wire of flexibility is organized in stainless steel fiber by arranging of this kind of structure, makes sand screen realize separating plugging function voluntarily.
In described SGP filtration beds, transverse fiber silk and longitudinal fiber silk are respectively using 3 ~ 10 as one group, between the upper and lower every layout, above below one group one group, the centre position carbon fiber wire often organized carries out interval setting, and all the other are stainless steel fiber.The carbon fiber wire of flexibility is organized in stainless steel fiber by arranging of this kind of structure, makes sand screen realize separating plugging function voluntarily.
The invention has the beneficial effects as follows:
For the exploitation of bottom water reservoir, it can mention good effect to the exploitation of high-water-cut oil-producing well, the recovery of oil well stopped production because of high water, old well, the producing well output that controls water content high oil well.
