STRUCTURED COMPOSITE COMPOSITIONS FOR TREATMENT OF SUBTERRANEAN WELLS

A structured composite is comprised of particulates having particle size distribution of at least two modes and a binder. The particle size distribution is preferably bi-modal or tri-modal. The composite may further contain a density-modifying agent for modifying the density of the composite. The pa...

Summary:A structured composite is comprised of particulates having particle size distribution of at least two modes and a binder. The particle size distribution is preferably bi-modal or tri-modal. The composite may further contain a density-modifying agent for modifying the density of the composite. The particulates are preferably substantially spherical and may be ultra lightweight (ULW) materials. The resulting composites exhibit the requisite strength to survive downhole imposed stresses and temperatures. Un composite de structure constitué de matières particulaires ayant une distribution en dimension des particules d'au moins deux modes et d'un liant. La distribution en dimension des particules est préférablement bimode ou trimode. Le composite peut également contenir un agent de modification de la densité pour modifier la densité du composite. Les matières particulaires sont préférablement sphériques et peuvent être des matériaux ultra légers. Les composites qui en résultent présentent la résistance nécessaire pour résister aux tensions et aux températures imposées en conditions de fond.
