Abstract
The utility model belongs to the technical field of the sand filtering pipe used in the oil well of the oil field. The utility model is provided with a cylindrical hollow drum body 1 made of polymer materials; one end of the hollow drum body is provided with an annular groove 2 whose diameter is bigger than the inner diameter of the hollow drum body 1, and the other end of the hollow drum body 1 is provided with an annular groove 3 whose diameter is smaller than the outer diameter of the hollow drum body 1; the wall thickness of the hollow drum body 1 is 15-28 mm. The utility model has convenient installation and operation, higher installation accuracy, and the advantage that the success ratio of the work achieves more than 95%, and has the advantages of no crushing, no deformation, simple structure, light weight, small volume, good corrosion-resisting property and long service life.
Description
The utility model belongs to the sand screen technical field of using in the oilfield.
Sand screen is installed in oil well, and the sand when pumping to reduce in the oil is to the damage of machine.The sand screen that uses in each oil field of China mainly divides three kinds now: quartz sand sand screen, ceramic sand screen and powder metallurgy sand screen.Though they respectively have advantage.But also have some deficiency simultaneously: their structure is and is provided with a joint between two pipes, complex procedures, installation inconvenience during installation; When tube wall was thicker, installation difficulty was big, and is easily broken again when tube wall is thin, cause installing complicated, that accuracy is installed is low; Easily broken; Corrosion-resistant; Cost height and filtering accuracy are low or the like.
The purpose of this utility model is, a kind of macromolecular material sand screen is provided, make it have in light weight, volume is little, intensity is high, easy for installation, accuracy height, corrosion resistance and good, shock-resistant, indeformable and be difficult for advantage such as fragmentation be installed.
The technical solution of the utility model is, adopt macromolecular material that it is made cylinder type hollow cylindrical shell 1, one end of hollow cylindrical shell 1 is offered the cannelure 2 of diameter greater than hollow cylindrical shell 1 internal diameter, and the other end of hollow cylindrical shell 1 is offered the cannelure 3 of diameter less than hollow cylindrical shell 1 external diameter.The wall thickness of hollow cylindrical shell 1 is the 15-28 millimeter, the wall thickness of hollow cylindrical shell 1 be 18 millimeters better.Its intensity and cost are combination preferably.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
1 is hollow cylindrical shell among the figure, adopts macromolecular material to make, and an end of hollow cylindrical shell is offered the cannelure 2 of diameter greater than hollow cylindrical shell 1 internal diameter, and the other end of hollow cylindrical shell 1 is offered the cannelure 3 of diameter less than hollow cylindrical shell 1 external diameter.The wall thickness of hollow cylindrical shell 1 is the 15-28 millimeter.The wall thickness of hollow cylindrical shell 1 is 18 millimeters.Wall thickness of the present utility model is to draw from hundreds of tests.Its numerical value is the better combination of intensity of the present utility model and cost.That is: intensity is higher, and cost is lower.The intensity of the utility model wall thickness and the combination of cost are all better than any effect in the existing sand screen.
The utility model can be installed in the inner use of oil well, energy owing to can make thinner wall thickness Enough reach the phenomenon that definitely prevents the sand screen fragmentation, can improve by a relatively large margin operating efficiency, reach better Sand controlling result. The utlity model has easy to installly, it is higher that accuracy is installed, job success Rate reaches the advantage more than 95%, and have not broken, indeformable, simple in structure, in light weight, The advantages such as volume is little, corrosion resistance and good and long service life.
