Abstract: Изобретение относится к технологии бурения нефтяных и газовых скважин, вертикальных и наклонных в высокопроницаемых трещиноватых газонасыщенных коллекторах с градиентом пластового или порового давления преимущественно 0,002-0,009 МПа/м. Изобретение может быть использовано в первую очередь при проводке скважин в сложных горно-геологических условиях, характеризующихся полным поглощением бурового раствора, вызывающим газопроявление, которое не удается ликвидировать стандартным образом. Согласно способу разрушают породу с прямой промывкой буровым раствором по бурильной колонне. Удаляют выбуренную породу на дневную поверхность. По достижении в процессе бурения поглощающего трещиноватого газонасыщенного пласта, о чем судят по падению давления и отсутствию циркуляции, меняют промывочный агент на буровой раствор с малым содержанием твердой фазы и удаляют выбуренную породу в зону поглощения. Формируют гидравлический затвор в затрубном пространстве скважины в виде плавающего столба над поглощающим пластом. В качестве плавающего столба используют столб стабильной трехфазной пены, которую получают путем аэрации и смешивания непосредственно перед закачкой в затрубное пространство скважины пенообразующей жидкости и воздуха с плотностью пены и высотой столба, достаточных для приведения в равновесие системы скважина - пласт. По достижении верхней границей плавающего столба трехфазной пены устья скважины аэрацию подачей воздуха прекращают и начинают подачу поверх столба трехфазной пены порции пенообразующей жидкости для придавливания пены. Повышается эффективность строительства скважин за счет сокращения затрат времени и материалов на ликвидацию осложнений. 6 з.п. ф-лы.
