PROPPANT, METHOD OF PRODUCTION AND METHOD OF HYDRAULIC BREAK OF FORMATION USING PRODUCED PROPPANT |
摘要 |
FIELD: oil and gas production. ^ SUBSTANCE: in method of proppant production, particles of which have density 1.5-4.0 g/cm3 and hardness not less, than 4, there are used at least two different types of slag of industrial production; said types of slag are crumbled before or after their mixing; produced mixture of slag powders is mixed with crumbled bauxite or crumbled alumina at ratio mixture of slag powders : crumbled bauxite or crumbled alumina 7:3 by weight; it is granulated and baked to sintering at temperature from 1300 to 1600C. Proppant produced by the described method is used for hydraulic break of a formation at stresses provoking healing of ruptures up to 15000 psi. The invention is developed in dependant claims. ^ EFFECT: production of proppant of high operation properties and low prime cost. ^ 12 cl, 2 tbl |
