Through hole geopolymer sand filter pipe

Abstract

The invention discloses a through hole geopolymer sand filter pipe. The through hole geopolymer sand filter pipe comprises a base pipe and a filter layer; the filer layer is a through hole geopolymerfilter layer; a slotted hole is formed in the base pipe; the through hole geopolymer filter layer covers the slotted hole completely when arranged on the outer wall of the base pipe in a sleeving mode; at least one consolidating sleeve is arranged on the outer wall of the through hole geopolymer filter layer in a sleeving mode and connected to the outer wall of the through hole geopolymer filter layer through a heated adhesive; and the upper end and the lower end of the through hole geopolymer filter layer are connected with an upper protection cover and a lower protection cover through adhesives correspondingly, and the upper protection cover and the lower protection cover are both welded to the base pipe. The slotted hole is reasonable in design; the filter layer is made of a geopolymermaterial, and the through hole geopolymer sand filter pipe has obvious advantages the filter layer is mounted and connected in the mode that the unconventional adhesives are heated for consolidating,and the strength of the consolidating part is high; and the multiple consolidating sleeves are arranged on the outer wall of the filter layer, so that the strength of the consolidating part is improved again while the strength of the filter layer is improved.

Description

technical field [0001] The present invention relates to sand filter pipes for oil fields, in particular to through-hole geopolymer sand filter pipes. Background technique [0002] At present, oil field development is in the stage of low-cost operation, and the integration of various processes needs to adapt to this development method. For sand control technology, sand control of sand filter tubes is stable, reliable, and relatively cheap, and its application prospects are broad. It would be more attractive to develop a more high-quality and cheaper sand filter pipe. The current sand filter pipes mainly include metal mesh, coated sand, ceramics and various composite materials. Relatively speaking, metal mesh has simple structure, strong wear resistance, and is widely used, but its ability to retain powder and fine sand is poor, and the cost is high; coated sand and ceramic sand filter pipes have strong sand retaining ability, but their toughness is poor. The collision is fra...

Relatively speaking, metal mesh has simple structure, strong wear resistance, and is widely used, but its ability to retain powder and fine sand is poor, and the cost is high; coated sand and ceramic sand filter pipes have strong sand retaining ability, but their toughness is poor. Collision is fragile, it is difficult to go down the well, and the cost is also high
