Abstract
Изобретение дает способ перфорирования скважин с буферной жидкостью для перфорирования, содержащей вязкоупругое поверхностно-активное вещество, по существу, останавливающее фильтрацию в пласт текучей среды после перфорирования в условиях репрессии. В другом аспекте изобретения создана сама буферная жидкость для перфорирования. Скважина имеет ствол, обсаженный в общем цилиндрической обсадной колонной, по меньшей мере, на участке ствола (то есть ствол обсажен, хотя не обязательно по всей длине). Ствол скважины проходит сквозь подземный пласт, содержащий углеводородные пластовые текучие среды (такие как нефть и/или газ), по меньшей мере, в некоторых слоях. Способ содержит размещение в стволе скважины перфорирующего устройства, включающего в себя по меньшей мере один перфорирующий заряд взрывчатого вещества, который можно подрывать для перфорирования обсадной колонны и обеспечения входа пластовых текучих сред в ствол скважины. Обсадная колонна размещена между подземным пластом и перфорирующим устройством. Буферную жидкость для перфорирования, включающую в себя по меньшей мере одно вязкоупругое поверхностно-активное вещество размещают в стволе скважины между перфорирующим устройством и обсадной колонной, по меньшей мере, на участке ствола скважины. Другими словами, буферная жидкость для перфорирования присутствует в стволе скважины вблизи перфорирующего устройства. Заряд (заряды) взрывчатого вещества в перфорирующем устройстве подрывают, так что перфорирующее устройство образует по меньшей мере один перфорационный канал в обсадной колонне, обеспечивающий приток углеводородных пластовых текучих сред из
