Title
(EN) USE OF COATED PROPPANT TO MINIMIZE ABRASIVE EROSION IN HIGH RATE FRACTURING OPERATIONS
(FR) UTILISATION D'UN AGENT DE SOUTÈNEMENT ENROBÉ POUR MINIMISER L'ÉROSION ABRASIVE DANS DES OPÉRATIONS DE FRACTURATION À HAUT DÉBIT
Abstract
(EN)
Methods for reducing wear in pumping components during fracturing operations. A coated proppant is used that causes less wear on the pumping components as the proppant is pumped into the wellbore. The proppant coating consists of a substrate having a coating thereupon which eliminates sharp edges on the substrate and functions as a lubricant to materially reduce mechanical erosion of the pumping components. The proppant substrate may consist of any of a number of materials, including sand, ceramic, resin coated sand, or resin coated ceramic particle. The coating preferably comprises one or more layers of one or more of the following materials (or the coating having low friction coefficients is part of a mixture of the coating): antimony trioxide, bismuth, boric acid, calcium barium fluoride, copper, graphite, indium, fluoropolymers (FTFE), lead oxide, lead sulfide, molybdenum disulfide, niobium diselenide, polytetraf luoroethylene, silver, tin, or tungsten disulfideor zinc oxide. The coating material may be applied to the substrate in a number of ways known in the art.

Procédés servant à réduire l'usure dans des composants de pompage au cours d'opérations de fracturation. On utilise un agent de soutènement enrobé lequel provoque une moindre usure des composants de pompage lorsque l'agent de soutènement est pompé dans le forage du puits. L'agent de soutènement enrobé est constitué d'un substrat ayant un enrobage sur celui-ci lequel élimine les arêtes vives présentes sur le substrat et sert de lubrifiant pour réduire sensiblement l'érosion mécanique des composants de pompage. Le substrat de l'agent de soutènement peut être constitué de l'une quelconque d'un certain nombre de matières, dont des particules de sable, de céramique, de sable enrobé de résine ou de céramique enrobée de résine. L'enrobage comprend de préférence une ou plusieurs couches d'une ou plusieurs des matières suivantes (ou bien l'enrobage ayant de faibles coefficients de frottement fait partie d'un mélange formant l'enrobage) : le trioxyde d'antimoine, le bismuth, l'acide borique, le fluorure de calcium et de baryum, le cuivre, le graphite, l'indium, des polymères fluorés (FTFE), l'oxyde de plomb, le sulfure de plomb, le disulfure de molybdène, le diséléniure de niobium, le polytétrafluoroéthylène, le disulfure d'argent, d'étain ou de tungstène ou l'oxyde de zinc. La matière d'enrobage peut être appliquée au substrat d'un certain nombre de manières connues dans l'art.
