Abstract
The utility model relates to a 45W Pa high-pressure filtering device for an oil field water flooding well. The utility model is formed by the improvement of the high-pressure filtering device. In the utility model, the compressive strength of a casing is enhanced, a coupler is used to connect, the speeds of loading and unloading are improved, the pipe box is improved, the piping number is increased, the filtering area is improved, and the dead zone and the air exhaust of the upper part of the liquid collecting box are eliminated, which causes the whole structure to become reasonable and practical. The filtering medium adopts the currently advanced pipes of PE, PEC, PVC or the mother baby super filtering pipe at home, and the filtration accuracy is high. The utility model is easy to regenerate and to use repeatedly, and is suitable for the filtration of the water quality for the hyposmosis oil field water flooding well.
Description
The utility model is a kind of 45MPa oil-field flooding well head high pressure filtering device, especially is applied to the water injection well of low permeability oil field.
At present the high pressure filtering device that uses of oil-field flooding well head have multiple, more advanced, precision is higher, practicality is stronger is water injection well high pressure filter and Chinese patent 89203258.8 high pressure filtering devices that U.S. bohr company produces.These two kinds of strainers respectively have advantage, but because of compressive resistance is not enough, renew cartridge inconvenience more, and the filter core of bohr company can not be regenerated, and operating cost is high and can not satisfy under the 45MPa situation and use.
It is higher that the utility model has screened domestic precision, and reproducible PE, PEC, PVC and four kinds of filter pipes of mother and sons' ultrafiltration pipe are filter medium.But designed the new model structure of quick loading and unloading backwash, exhaust and chemical regeneration, enabled long-term continuously use the under the 45MPa high pressure.
Technical solution of the present utility model is, a kind of is the 45MPa high pressure filtering device of filter medium with PE, PEC, PVC, mother and sons' ultrafiltration pipe, it is characterized in that having the alloy steel cartridge type housing of a vertical layout, the top is arch form loam cake (5), and the bottom is alloy steel cylindrical shell (1), adopts hookup or flange to connect, the steel ring sealing, the tube internal upper part is equipped with liquid-collecting box (3), suspends chimney filter (2) on the liquid-collecting box lower face plate in midair, and its connected mode is screwed connection.
Technical solution of the present utility model is, a kind of with the two hookups not of uniform size or the arch form loam cake of two flanges, it is characterized in that the center leaves fluid hole (11), hermetically-sealed construction is provided with packing pressure cap (7), sealed packing (6), sealed step (12), sealing thread (13), and packing pressure cap (7) adopts with fluid hole (11) and is threaded.
Technical solution of the present utility model is, a kind of round liquid-collecting box (3), it is characterized in that liquid-collecting box face boss is for the tube circle, what be interlinked to the outside in top center is welded with goes out fluid catheter (10), go out the fluid catheter bottom and be welded with a steam vent short circuit (9), the filtration short tube is housed on it, has solved exhaust and the dead-time problem on the box; Lower face plate is welded with inside and outside connection, single head screw thread pipe nipple (8) different in size, and pipe nipple length is arranged as inside and outside alternating layers welding, adopts this kind mode, and comparable identical length pipe nipple increases dress chimney filter number and reaches more than 1/3rd on the identical area of a circle.
It is many that advantage of the present utility model is to install chimney filter quantity, filter area is big, the filtering accuracy height, the type compactness, rational in infrastructure, operating pressure can reach 45MPa, but and backwash and chemical regeneration, by the control differential filter, can be widely used in the oil-field flooding well head, provide a kind of novel oil-field flooding well head high-pressure filteration equipment for domestic.
