Abstract: Группа изобретений относится к нефтегазовой промышленности и может быть использована для повышения эффективности добычи углеводородов из нефтекерогеносодержащих пластов сланцевых формаций без использования гидравлического разрыва пласта, а также для добычи природных битумов, тяжелых и высоковязких нефтей. Технический результат - повышение нефтеотдачи нефтекерогеносодержащих пластов за счет формирования их высокой проницаемости. Способ добычи высокотехнологичной нефти включает термохимические воздействия на продуктивный пласт рабочими агентами. Их приготавливают на дневной поверхности и инжектируют в заданной последовательности в околоскважинную зону продуктивного пласта по колонне теплоизолированных насосно-компрессорных труб. Затем из продуктивного пласта в режиме фонтанирования скважины отбирают высокотехнологичную нефть и доставляют ее на дневную поверхность по колонне теплоизолированных насосно-компрессорных труб. Процесс добычи осуществляют циклически. Каждый из циклов включает несколько этапов. Первым этапом каждого цикла является этап инжектирования в продуктивный пласт рабочего агента воздействия. На последнем этапе осуществляют отбор из продуктивного пласта высокотехнологичной нефти. При этом на этапе отбора нефти каждого цикла контролируют внутрипластовое давление. Как только это давление понизится до заранее заданного значения, прекращают отбор. 2 н.п. ф-лы, 4 ил., 1 табл.

Abstract: Группа изобретений относится к обработке стеклоизделий, а именно к способу обработки полых стеклоизделий и лазерной установке для его осуществления. Технический результат заключается в повышении качества края стеклоизделия, получаемого при отделении удаляемой части, чтобы практически полностью исключить или свести к минимуму дальнейшую обработку края. Согласно способу обработки полых стеклоизделий с помощью воздействия лазерного излучения от вращающегося стеклоизделия отделяют удаляемую часть вдоль заданной линии разделения. Указанный способ включает: первый этап предварительной обработки и второй этап отделения удаляемой части. На первом этапе работающий в непрерывном режиме лазерный луч направляют на поверхность вращающегося стеклоизделия в точку на линии разделения, чтобы задать вдоль линии разделения первую непрерывную зону воздействия лазерного излучения. На втором этапе работающий в непрерывном режиме лазерный луч направляют на поверхность вращающегося стеклоизделия в точку на линии, смещенной от линии разделения в сторону от удаляемой части, чтобы задать вдоль упомянутой смещенной линии вторую непрерывную зону воздействия лазерного излучения. Упомянутая смещенная линия находится на периферийной границе первой непрерывной зоны воздействия, и вторая непрерывная зона воздействия имеет большую ширину, чем первая непрерывная зона воздействия. 2 н. и 15 з.п. ф-лы, 9 ил.

In the claimed method, the horizontal and vertical geometric factors of accuracy degradation are calculated. Implementation of a complete search of the variants of RNE placement in a predetermined area or on a given trajectory involves construction of a search matrix consisting of points - centres of areas of possible location of the RNE, use of a digital elevation model to calculate the value of elevation at the current point of installation of the RNE (the search matrix point), calculation of the values of horizontal and vertical geometric factors for each configuration of the RNE, sorted in order of increasing of the spatial geometric factor. The RNE configurations that do not provide values of horizontal and vertical geometric factors less than the maximum permissible are then excluded. Area restrictions (visibility areas, permitted areas) are converted into binary masks. 
     EFFECT: increase in the accuracy of determining the location by a radio engineering range measuring method due to the optimisation of placement of reference navigation equipment (RNE) in a predetermined area of operation of the navigation object.
