Description
Technical field
The utility model relates to a kind of oil exploration equipment field, specifically a kind of multifunctional filtering screen casing.
Background technology
Along with the fast development of China's economy, oil exploitation industry is also more and more flourishing, and oil exploration equipment is with more and more.Wherein in petroleum recovery operations, screen casing is a kind of important equipment, often adopts completion or oil extraction sand prevention in advance.At present, more screen casing is used to be wire-wrapped screen, there are some problems in this screen casing when going into the well, especially when suppressing the curved segment by high angle hole or horizontal well, inevitably collide with the borehole wall or sleeve pipe, extrude and rub, easily there is sleave phenomenon, cause screen damage or gap distortion, total completion time and sand controlling result is caused to reduce or lost efficacy, and because of the inflammable characteristic of oil, if during screen casing work, temperature is too high affect work safety, the sand coarse aggregate ratio of once having filtered in oil is more difficult, sandstone easily blocks screen casing, affects operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of multifunctional filtering screen casing, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of multifunctional filtering screen casing, comprise oil guide pipe, hickey, inner screen, outer screen, beam, pin, temperature pick up, hairbrush, expansion link and control valve, described oil guide pipe bottom is connected with interface helixseal on hickey, hickey lower interface is connected with inner screen helixseal, inner screen top is provided with control valve, inner screen is enclosed within outer screen inside, inner screen and outer screen junction are provided with sealing ring, the inner screen being enclosed within outer screen inside is provided with spiral slot, outer screen is provided with sieve aperture, beam is provided with outside outer screen, pin is provided with bottom outer screen, inner screen, temperature pick up is established between outer screen, inner screen, also hairbrush is provided with between outer screen, hairbrush is fixed in outer screen top inner wall by expansion link.
As further program of the utility model: described oil guide pipe is anticorrosion compound oil casing pipes.
As the utility model further scheme: described inner screen, outer screen adopt stainless steel to make, and inner screen, outer screen are coated with anticorrosion Withstand voltage layer.
Compared with prior art, the beneficial effects of the utility model are: the utility model oil guide pipe is anticorrosion compound oil casing pipes, conveniently move when oil well, especially when suppressing the curved segment by high angle hole or horizontal well, not fragile oil guide pipe, inner screen, outer screen degree has anticorrosion Withstand voltage layer, improve application life, screen casing and the borehole wall or sleeve pipe collide, when extruding and friction, beam effectively protects screen casing, pin prevents the dope blocking screen casings such as the mud bottom oil, influence of crust deformation work can not be there is in slot because of collision, and it is with low cost, oil is by sieve aperture and slot twice filtration, good working effect, temperature during screen casing work monitored at any time by temperature pick up, prevent it from affecting work safety because temperature is too high, timing is by the hairbrush cleaning slot of inner screen and the sieve aperture of outer screen, prevent silt blocking from affecting work, have and very highly make practical value.
Accompanying drawing explanation
