Abstract
The utility model relates to a well-top water treatment device for a water injection well of an oil field. The utility model is characterized in that the well-top water treatment device is composed of a press cap 1, a sealing ring 2, a casing 3, an outer sieve tube 4, a magnet 5, a filtering net 6, an inner sieve tube 7 and a press cover 8, and has the advantages of novel structure and convenient operation. The well-top water treatment device can be arranged conveniently at the well top of the water well, can clean the filtering net through the back washing, changes conveniently the filtering net, and can ensure the qualification of injecting water quality. An injecting layer is not clogged, the oil field development conducts successfully, and the utility model is easy to popularize and use in the oil field.
Description
The utility model relates to a kind of water injection well well head water treatment facilities that is used for the oil field.
At present, in the field produces, water that water injection well injects is all handled at multi-purpose station, be transported to measuring station (or water-injection station) again, be assigned to water injection well by measuring station (or water-injection station) again, main existing problems are: long from multi-purpose station to water injection well well head pipeline (about 1～6km), because pipeline uses for a long time, there be scale formation and corrosion phenomenon in various degree in inner surface of tube wall, impurity often comes off, add the suspension that contains in the water, machines such as tiny silt particle are assorted, all can inject the stratum, cause implanted layer to stop up, cause injected water volume fewer and feweri, water injection pressure is more and more higher, annotates when serious and does not intake, and influences oil field development and normally carries out.
Task of the present utility model is to provide a kind of water injection well well head water treatment facilities, adopts this device, can will inject water at the water injection well well head and handle again, removes impurity, guarantees not stop up implanted layer, and oil field development is normally carried out.
The utility model is to realize like this, it is made up of pressure cap 1, sealing ring 2, shell 3, outer screen pipe 4, magnet 5, screen pack 6, interior screen casing 7, gland 8, its assembling process is as follows: earlier magnet 5 is contained in the outer screen pipe 4, screen casing 7 in reinstalling, between outer screen pipe 4 and interior screen casing 7, be pressed into screen pack 6, first-class gland 8 is fixed interior screen casing 7, screen pack 6, magnet 5, and in the shell 3 that is with sealing ring 2 of then outer screen pipe 4 being packed into, first-class pressure cap 1 is promptly assembled and finished.
During use, this water injection well well head water treatment facilities is contained in the water injection well well head, makes water filling water enter inner chamber by shell 3 side mouths, screen casing 7 in entering by outer screen pipe 4, screen pack 6 again by magnet 5, is injected into implanted layer by the outflow of shell 3 prosopyles.When screen pack 6 stops up, but changing the mouth of a river, water inlet carries out the backwash de-plugging, can unload outer screen pipe 8 when serious, unload lower pressing cap 1, gland 8, interior screen casing 7 again, change screen pack 6.
The utility model novel structure, easy to operate, practical, can be installed in the well well head very easily, and can clean filter screen by backwash, it is also very convenient to change filter screen, it is qualified so just can to guarantee to inject water quality, does not stop up implanted layer, and oil field development is carried out smoothly.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.
Accompanying drawing shows structure sketch drawing of the present utility model.Pressure cap 1 is the cap shape, and an end blind hole, an end have negative thread; Sealing ring 2 is a standard component; Shell 3 is a tubular, and there is an outlet side, is oil field 62.5mm standard clip head, and an end has the pin thread that matches with pressure cap 1, and the other end is oil field 62.5mm standard clip head and there is one section negative thread the inboard; In the middle of the outer screen pipe 4 is screen casing, and an end has negative thread, and an end has diameter 62mm pin thread; Magnet 5 is cylindric; Screen pack 6 is flat-shaped stainless steel wire; Interior screen casing 7 is the screen casing shape; Gland 8 is and covers shape, and cylindrical is a pin thread, and an end has handle.
