Abstract
The utility model provides an 'underground oil field controllable porosity sand-proof sieve tube 'used for sand prevention of underground oil field in the process of the production of crude oil. Because the utility model is provided with a self-cleaning sand removing groove, sand-proof porosity can be designed according to different wells and sand specimen granules of different horizon; the production can be carried out through controlling the sand-proof porosity of the sieve tube by a computer, and a sand removing passage and sand washing process are used for preventing and treating powder dust and sand so as to effectively prevent blocking and jamming the sand in an oil well, prolong the production period of the oil well, and increase well yield.
Description
The utility model provides " oil is by down-hole controlled porosity sand control screen " that sand control is used in the crude oil production process of down-hole, a kind of oil field.
Oil field sand control in crude oil production is the biggest problem at present, owing to often shake out in the oil reservoir, bring very big difficulty to oil exploitation, the lighter's oil well production equipment that weares and teares, weight person causes sand card or damage equipment to cause oil well to stop production, so each state is is all researching and solving, China more payes attention to, the sand control technique of present China also needs perfect, and it is that the degree of porosity size can not artificially be controlled that there are subject matter in the metal wool screen casing of current application or ceramic post sintering screen casing; To shaking out of different layers position, down-hole, oil field, can not effectively control sand control; Existing sand control technique can not self-cleaning sediment outflow; The dust sand problem of preventing and treating can't resolve so influence the production time of crude quality and oil well.
At the problems referred to above, the purpose of this utility model is to overcome deficiency of the prior art, and down-hole, a kind of oil field controlled porosity sand control screen is provided, and it is provided with self-cleaning sediment outflow groove, and the sediment outflow groove can be at the screen casing effluent sand; The sand control degree of porosity can be controlled; Can prevent and treat dust sand, realize to control sand control.
The utility model is achieved in that at first from market or oilfield material department buys material requested by accompanying drawing, and with 4 chromium, 13 stainless steels processing box cupling (1), thickness of pipe wall is that 4mm is connected with well casing then; Processing parent tube (2), parent tube is the carrier of stainless steel screen casing (4), on have box cupling and flow string to join, lower end and tail pipe join, circulate to guarantee the oil gas after the screen casing filtration in the hole of parent tube staggered even distribution Ф 10mm at the design position of screen casing; Plug (3) is set upright in reprocessing, set upright plug and bearing the fixing of stainless steel screen casing (4) and parent tube (2), set upright stainless steel screen casing (4) in it, its outer outer pillar (5) of setting upright, uniform sediment outflow groove on plug, be used to dredge gas stream and the sand setting of the screen casing filtration of draining, setting upright plug is truncated cone-shaped, and it plays the fixation of screen casing, pillar and parent tube; Processing stainless steel screen casing (4), stainless steel screen casing are the major technique facilities of high temperature sand control, and the design of sand control degree of porosity is according to oil well sand sample and geologic information, the appliance computer design, the degree of porosity of anti-sandpipe is corresponding with the reservoir sand of oil well; Process outer pillar (5), it mainly is at when construction protection screen casing, and pillar (5) is provided with uniform hole or groove so that be screen casing mediation gas stream when producing outside, above-mentioned component-assembled is then constituted " down-hole, oil field controlled porosity sand control screen ".
The utility model is compared with prior art: since this utility model be provided with the few groove of self-cleaning row can be at stainless steel screen casing effluent sand; The sand control degree of porosity can be controlled; Can prevent dust sand, have good sediment outflow effect.
Accompanying drawing is down-hole, an oil field controlled porosity sand control screen general structure schematic diagram, and 1 is box cupling, the 2nd among the figure, and parent tube, the 3rd is set upright plug, the 4th, stainless steel screen casing, the 5th, outer pillar.
An embodiment is described in conjunction with the accompanying drawings: at first from market or oilfield material department buy material requested, then press accompanying drawing processing box cupling (1), processing internal diameter with 4 chromium, 13 stainless steels by accompanying drawing is Ф 70-114mm, wall thickness is the box cupling (1) of 4mm; Processing parent tube (2), parent tube is the carrier of stainless steel screen casing (4), the upper end has box cupling and flow string to join, and parent tube (2) is the hole of beating Ф 10mm at the design position of stainless steel screen casing, and pitch-row is that 5mm is staggered this hole of uniform arrangement and is mainly used in the oil gas of guaranteeing after screen casing filters and circulates; The truncated cone-shaped that is processed into Ф 76-101mm with 4 chromium, 13 stainless steels is set upright plug (3), it mainly plays the fixation of stainless steel screen casing (4) and outer pillar (5) and parent tube (2), set upright its outer outer nurse's pipe (5) of setting upright of stainless steel screen casing (4) in it, and be provided with uniform self-cleaning sediment outflow groove on the plug (3) setting upright, regularly can implement the backwash sediment outflow can extend manufacture cycle at stainless steel screen casing (4) effluent sand; Be processed into the stainless steel screen casing (4) of Ф 78-114mm with 1 chromium, 18 nickel, 9 titanium corrosion resistant plates, it can play the effect of high temperature sand control, has the high-temperature-resistant and anti-corrosion performance, the sand control degree of porosity of stainless steel screen casing (4) can determine that degree of porosity production of the stainless steel screen casing (4) that computerizeds control makes it corresponding with the particle of reservoir sand according to the sand sample particle and the geologic information of different oil wells and different layers position; Be processed into the outer pillar (5) of Ф 88-126mm with 4 chromium, 13 stainless steels, pillar (5) is provided with uniform hole or groove outside, is stainless steel screen casing (4) mediation gas stream when making it production operation, and outer pillar (5) is protected stainless steel (4) when construction operation.With above-mentioned each component-assembled: go up at parent tube (2) stainless steel screen casing (4) is installed, and pillar (5) outside outside it, installing, with setting upright plug (3) above-mentioned each parts are fixed into one, then connect box cupling (1) and then constitute " down-hole, oil field controlled porosity sand control screen " on the top of setting upright plug (3).
Claims (1)
1, a kind of " down-hole, oil field controlled porosity sand control screen " it by stainless steel screen casing (4) go up to be installed at parent tube (2), and pillar (5) is fixed into one with setting upright plug (3) with above-mentioned each parts outside install its outside, then connect box cupling (1) and constitute, it is characterized in that on the top of setting upright plug (3):
