摘要: The invention provides a sand-controlling screen pipe. pipe comprises base and connecting part arranged at one end of the pipe; least set filtration gaps is formed in axial direction each composed plurality gaps; multiple are uniformly radial tubular body made aluminum alloy. problems that mining progress delayed economic loss oil well scrapping occurs since an existing can not be salvaged after being blocked or buried solved through
