METHODS OF FORMING PERMEABLE SAND SCREENS IN WELL BORES

摘要

Methods of forming permeable sand screens in long, open hole well bores with in fluid producing zones are provided by the present invention. The methods basically comprise the steps of placing a perforated pipe in the open hole well bore, providing a hardenable composition which after being placed in a desired location cures into a hard mass, placing said hardenable composition in said well bore adjacent to said fluid produci ng zone within the interior of the perforated pipe therein, between the perforated pipe and the walls of the open hole well bore and within voids or fractures in the producing zone, causing the hardenable composition to cure into a hard permeable mass and drilling the hard permeable mass out of the interior of the perforated pipe.
