Description
Technical field
The utility model relates to a kind of screen casing applied in oil exploitation, particularly double-deck laser slotted screen pipe.
Background technology
It is one of major issue of running into of oil exploitation that oil, gas well shake out.Oil, gas well shake out and the most easily cause that oil reservoir sand buries, oil pipe sand plug, manifold of ground and oil tank amass sand, and severe patient causes oil well reduce or stop production, ground and underground equipment wearing and tearing, even casing failure, and oil well is scrapped; For in some, coarse granule loose sand form Oil/gas Well eat with traditional equipment sand control difficulty, because traditional manufacturing process is subject to the restriction of equipment and cutlery, slot width is the narrowest also at more than 0.25mm, and processing inconvenience, wayward, also limit simultaneously and apply.
Therefore in order to solve above-mentioned deficiency, the utility model provides a kind of double-deck laser slotted screen pipe at this.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design at this, and mechanism is simple, the oil exploited out can be carried out the double-deck laser slotted screen pipe filtered efficiently; The utility model adopts double medium filtration, outer filter rough sand, and internal layer filters fine sand, and sand controlling result is obvious, and the utility model price is low simultaneously, and simple installation, construction cost is low, instant effect, stable performance.
The utility model is achieved in that a kind of double-deck laser slotted screen pipe of structure, and comprise outermost pipe box, outer laser cuts screen casing, and internal layer laser cuts screen casing, oil pipe and oil well pump; Described outer laser cuts screen casing has scalping hole by Laser Processing, and is positioned at pipe box inside, cuts above screen casing and is provided with oil pipe, be provided with oil well pump at oil pipe top at outer laser; Described internal layer laser cuts screen casing has fine mesh by Laser Processing, and being installed on outer laser, to cut screen casing inner and be positioned at bottom oil pipe.It is filter for first time that described outer laser cuts screen casing, can block filter coarse sand; It is for secondary filter that described internal layer laser cuts screen casing, can block fine sand.
Described internal layer laser cuts screen casing and outer laser cuts controllability, the adjustability that screen casing utilizes laser, and Development and Production, adopts laser cutting simultaneously, and all working once completes, and ensure that the stability of Product Precision
According to double-deck laser slotted screen pipe described in the utility model, described internal layer laser cuts bottom screen casing and is provided with internal layer plug, and described outer laser cuts bottom screen casing and is provided with outer plug.
According to double-deck laser slotted screen pipe described in the utility model, described outer laser cuts screen casing and internal layer laser and cuts between screen casing and form ectonexine slot tube space; Described pipe box and outer laser cut between screen casing and form oil pocket.
Principle of the present utility model is as follows:
Well liquid is by the suction force of oil well pump, and the inlet from oil jacket space by outer laser slotted screen pipe enters; Any gravel comparatively thick is blocked in outer laser and cuts outside screen casing, by shaft bottom, own wt whereabouts; The scalping hole that well liquid cuts screen casing by outer laser enters outer laser and cuts the ectonexine slot tube space that screen casing and internal layer laser cut screen casing; Internal layer laser cuts the more outer laser of screen casing fine mesh, and to cut the scalping hole of screen casing much smaller, after again filtering, comparatively clean well liquid cuts the fine mesh of screen casing through internal layer laser, enter internal layer laser to cut screen casing and be then drawn out of well head, then cut oil pocket tenesmus between screen casing to shaft bottom through ectonexine laser by the gravel of secondary filter.
The beneficial effects of the utility model:
The utility model is reasonable in design, and structure is simple, easy to use, by reasonably arranging that outer laser cuts screen casing and internal layer laser cuts screen casing, completes twice filtration of well oil, outer filter rough sand, and internal layer filters fine sand, and sand controlling result is obvious.The utility model price is low simultaneously, and simple installation, construction cost is low, instant effect, stable performance.
