Claims (1)

Способ изоляции водопроявляющих пластов, включающий образование в стенке скважины горизонтальной каверны и последующее заполнение ее цементным раствором, отличающийся тем, что в скважину спускают перфоратор на колонне насосно-компрессорных труб, которую оборудуют реперным элементом, геофизическим методом осуществляют точную привязку перфоратора к кровля водоносного пласта, если он расположен ниже продуктивного горизонта, иди к подошве водоносного пласта, если он расположен выше продуктивного горизонта, выполняют перфорацию обсадной колонны в виде одной или нескольких сплошных продольных щелей, расположенных по периметру обсадной трубы и своей протяженностью перекрывающих часть водоносного пласта, обращенную к продуктивному горизонту или полностью водоносный пласт, если он не превышает 6-8 м, вдоль образованных в трубе щелей вымывают гидромонитором сплошным продольные каверны в горной породе пласта, затем в интервале продольных щелей устанавливают цементный мост с задавливанием цементного раствора в пласт и оставлением его под давлением во время затвердевания, после чего разбуривают цементный мост в интервале продуктивного горизонта, перфорируют продуктивный горизонт гидромеханическим щелевым перфоратором и вызывают приток жидкости из продуктивного горизонта.A method of isolating water-producing strata, including the formation of a horizontal cavity in the borehole wall and its subsequent filling with cement mortar, characterized in that a perforator is lowered into the well on a tubing string that is equipped with a reference element, the perforator is precisely linked to the roof of the aquifer by a geophysical method, if it is located below the productive horizon, go to the bottom of the aquifer, if it is located above the productive horizon, perforation of the casing is performed strings in the form of one or several continuous longitudinal slots located around the perimeter of the casing and their length overlapping the part of the aquifer facing the productive horizon or completely aquifer, if it does not exceed 6-8 m, wash along the cracks formed in the pipe with a continuous monitor longitudinal cavities in the rock of the formation, then in the interval of the longitudinal slits, a cement bridge is installed with the cement mortar crushed into the formation and left under pressure during solidification, after which they drill a cement bridge in the interval of the productive horizon, perforate the productive horizon with a hydromechanical slotted perforator and cause the flow of fluid from the productive horizon.
