Description
При производстве многократного поинтервального гидравлического разрыва пласта в нагнетательных и эксплуатационных скважинах, с целью выравнивани продвижени водонефт ного контакта по мощности пласта и вовлечени в разработку всей продуктивной части разреза пласта (всех пропластков), в жидкость разрыва добавл ют резиновые или пластмассовые шары дл последовательного перекрыти отверстий перфорации в различных интервалах разрыва пласта.In the production of multiple interval hydraulic fracturing in injection and production wells, in order to equalize the advancement of water-oil contact on the reservoir power and involve the development of the entire productive part of the reservoir section (all layers), rubber or plastic balls are added to the fracture fluid to block the holes perforations at different fracturing intervals.
Известные способы изготовлени резиновых и пластмассовых шаров дл этой цели не обеспечивают необходимой высокой прочности при сохранении достаточной эластичности.The known methods of making rubber and plastic balls for this purpose do not provide the necessary high strength while maintaining sufficient elasticity.
В описываемом способе этот недостаток устранен благодар тому, что сердцевины шаров штампуют из капрона, а затем обрезинивают.In the described method, this disadvantage is eliminated due to the fact that the cores of the balls are stamped from nylon, and then rubberized.
Шары диаметром 18-20 мм, изготовленные описанным способом, при производстве лабораторных и промышленных испытаний полностью оправдали свое назначение, плотно перекрыв отверсти перфорации до 12-14 мм и выдержав перепад давлени до 500 атм.Balls with a diameter of 18–20 mm, manufactured in the described manner, fully fulfilled their purpose in the production of laboratory and industrial tests, tightly blocking the perforation holes up to 12–14 mm and withstanding a pressure drop of up to 500 atm.
Предмет изобретени Subject invention
Способ изготовлени шаров дл поинтервального многократного гидравлического разрыва пласта, отличающийс тем, что, с целью придани шарам высокой прочности при сохранении эластичности, их сердцевины штампуют из капрона, а затем обрезинивают.A method of making balls for interval multiple hydraulic fracturing, characterized in that, in order to give the balls high strength while maintaining elasticity, their cores are punched from caprone, and then rubberized.
