Abstract
The utility model relates to a barrel hole type petroleum extraction filter sieve tube of a stainless steel corrugated mesh, belonging to the technical field of petroleum extraction equipment accessory, comprising a porous inner tube, a mesh barrel, a connecting hoop and a middle tightening tube, wherein hundreds of circular holes are arranged on the filter sieve tube; a thread connecting tube joint is arranged on the two ends of the filter sieve tube respectively; the mesh barrel is in a corrugated barrel shape; hundreds of strip holes are arranged on the surface of the mesh barrel; the mesh barrel is arranged at the outer surface of the filter sieve tube; the mesh barrels are connected through the middle tightening tube and fixed on the filter sieve tube; the two outer ends of the mesh barrels are fixed on the filter sieve tube through locating connecting hoops; the mesh barrel is formed in the corrugated shape, and the holes are strip-shaped, therefore the strength of the mesh barrel is enhanced, the filter area is increased, the flow rate is increased, the blockage is avoided and silts are prevented; and the yield and quality of petroleum are effectively increased, and the petroleum extraction cost is reduced.
Description
Technical field
the utility model relates to a kind of stainless steel ripple cylindrical mesh hole type oil recovery filter sieve tube, belongs to oil production equipment attachment technique field.
Background technology
are present, and the oil recovery filter sieve tube that uses on the oil production equipment is divided into common round and degree of depth type, common round complex structure, and intensity is low, and the filtering traffic area is little, is prone to mud sand plug plug filtration beds, and it is short application life to reduce filter effect; Degree of depth type filter sieve tube filtering layer is thick, and resistance is big, is prone to stop up, and life cycle is short, installs, dismantles inconvenience simultaneously.
Summary of the invention
are in order to overcome above-mentioned deficiency; The utility model provides a kind of stainless steel ripple cylindrical mesh hole type oil recovery filter sieve tube; This stainless steel ripple cylindrical mesh hole type oil recovery filter sieve tube can not only effectively filter silt, increases flow, and does not stop up method for using.
the utility model solves the technical scheme that its technical problem adopted: stainless steel ripple cylindrical mesh hole type oil recovery filter sieve tube is made up of porous inner tube, net tube, connection hoop, middle lock ring pipe; Be drilled with hundreds of circular holes on the filter sieve tube, its two ends are respectively equipped with the tube head that is threaded; The net tube is the wave cylindrical shape, and hundreds of bar holes are processed on its surface; The filter sieve tube external surface is settled the net tube, is connected by middle lock ring pipe between the net tube and is fixed on the filter sieve tube, and net tube two outer ends are fixed on the filter sieve tube by the hoop that is located by connecting respectively.
The beneficial effect of
the utility model is: net tube is processed corrugated, and its hole is that bar shaped has not only strengthened the intensity of net tube but also increased filter area, and flow is increased, and does not stop up, mud sand not; Effectively promote oil production rate and quality, reduce cost for oil production.
