Patent

CA 2616553

This invention relates to the oil and gas production industry and can be used for preventing fracture closing during fracturing of producing oil layers. Proppant comprising baked feedstock grains, with the difference that a burden material comprising silicon oxide and aluminum oxide at the aluminum oxide content of not less than 60% (by weight) is used as the feedstock; the apparent density of the proppant varies from 1.7 to 2.75 g/cm3

Cette invention est liée à l'industrie pétrolière et gazière, et peut être employée pour empêcher les fractures de se refermer pendant la fracturation dans le but de produire des nappes de pétroles. Agent de soutènement composé d'une matière première de grains cuits, à la différence près qu'une matière de remplissage formée d'oxyde de silicium et d'oxyde d'aluminium dans laquelle la teneur en oxyde d'aluminium n'est pas inférieure à 60 % (en poids) est utilisée comme matière première; la masse volumique apparente de l'agent de soutènement varie de 1,7 à 2,75 g/cm3.
