Abstract
1. Способ разработки при расконсервации скважин и нефтяной залежи в целом, включающий использование системы вертикально-латерального заводнения и фонтанного или механизированного способа добычи нефти, отличающийся тем, что в расконсервируемые простаивающие скважины спускают заливочные трубы выше кровли продуктивного пласта и осуществляют цементирование забоя скважины под давлением на высоту более толщины пласта; в скважинах, расконсервируемых в качестве добывающих, полученный цементный стакан разбуривают на глубину не более половины интервала продуктивного пласта, считая от кровли, дополнительно создают зумпф для спуска перфорационного оборудования и выполняют повторную перфорацию в интервале не более половины продуктивного пласта, считая от кровли, затем запускают скважину в добычу нефти фонтанным или механизированным способом; в скважинах, расконсервируемых в качестве нагнетательных, полученный цементный стакан разбуривают до подошвы пласта и создают зумпф для перфорационного оборудования, выполняют повторную перфорацию в интервале нижней одной трети пласта и запускают скважину под нагнетание воды. ! 2. Способ по п.1, отличающийся тем, что для снижения вероятности потери герметичности цементного камня выше или ниже интервала перфорации создание перфорационных отверстий выполняют методом гидропескоструйной перфорации.1. The development method for re-conservation of wells and the oil reservoir as a whole, including the use of a system of vertical-lateral waterflooding and a fountain or mechanized method of oil production, characterized in that the fill pipes are lowered into the unreserved idle wells above the top of the reservoir and cementing the bottom of the well under pressure to a height greater than the thickness of the reservoir; in wells mothballed as producing, the resulting cement cup is drilled to a depth of not more than half of the interval of the reservoir, counting from the roof, an additional sump is created to lower the perforating equipment and repeated perforation in the interval of not more than half of the reservoir, counting from the roof, is then launched a well in oil production fountain or mechanized way; in wells mothballed as injection wells, the resulting cement cup is drilled to the bottom of the formation and a sump for perforation equipment is created, repeated perforation is performed in the interval of the lower one third of the formation and the well is launched under water injection. ! 2. The method according to claim 1, characterized in that to reduce the likelihood of loss of tightness of the cement stone above or below the perforation interval, the creation of perforations is performed by the method of hydro-sandblasting.
