Abstract
A well screen for use in a subterranean well can include a filter with a nano-particle reinforcement. A method of constructing a well screen can include treating a filter with a nano-particle reinforcement.
Claims17
A well screen, comprising:
- a filter with a nano-particle reinforcement, wherein the filter comprises a permeable porous substrate, wherein the permeable porous substrate comprises a ceramic material, wherein the nano-particle reinforcement is disposed in pores of the ceramic material, wherein the ceramic material is mullite and is cast or molded directly onto a base pipe and is in abutment with the outer diameter surface of the base pipe along an entire axial length of the permeable porous substrate.
A method of constructing a well screen, the method comprising:
- treating a filter of the well screen with a nano-particle reinforcement, wherein the filter comprises a permeable porous substrate, wherein the treating comprises applying the nano-particle reinforcement to the permeable porous substrate, and wherein the permeable porous substrate comprises a ceramic material, wherein the treating comprises mixing the nano-particle reinforcement with the ceramic substrate and casting or molding it directly onto a base pipe so that it is in abutment with an outer diameter surface of the base pipe along an entire axial length of the permeable porous substrate and the nano-particle reinforcement is dispersed into pores of the ceramic material, and wherein the ceramic material is mullite.
