This invention relates to the oil and gas industry and can be used to prevent fracture closure by pumping special particulates (proppant) into the fracture after reservoir hydraulic fracturing. According to the invention, the proppant is particulates of sintered ceramic material which are shaped ideal spheres. The use of this type of proppant may increase the well production by 25 %.
L'invention concerne l'industrie du pétrole et du gaz et peut être utilisée pour éviter la fermeture par cassure en aspirant des éléments particulaires spécifiques (agents de soutènement) dans la cassure après la rupture hydraulique du réservoir. Selon l'invention, l'agent de soutènement est constitué d'éléments particulaires de matériau de céramique fritté qui sont façonnés en sphères parfaites. L'utilisation de ce type d'agent de soutènement peut augmenter de 25 % la production du puits.
