Наиболее распространенным породоразрушающим инструментом для бурения нефтегазовых скважин являются долота PDC (polycrystalline diamond compact). Подбор оптимальной геометрии резцов PDC является одной из ключевых задач при проектировании режущей структуры долот, позволяющей повысить эффективность разрушения горной породы. В настоящее время производители резцов PDC предлагают резцы с различной формой алмазного слоя (3D-резцы), которые особенно актуальны при бурении в осложненных горно-геологических условиях. В данной статье приведен обзор наиболее распространенных 3D-резцов и принципы их воздействия на горную породу. Показан опыт применения долот ООО НПП «БУРИНТЕХ» с 3D-резцами в условиях Восточной Сибири. The most common rock-crushing tool for drilling oil and gas wells are PDC (polycrystalline diamond compact) bits. The selection of the optimal geometry of PDC cutters is one of the key tasks in the design of the bit cutting structure, which allows to increase the efficiency of rock destruction. Currently, manufacturers of PDC cutters offer cutters with different shapes of the diamond layer (3D cutters), which are especially relevant when drilling in complicated geological conditions. This article provides an overview of the most common 3D cutters and the principles of their impact on rock. The trial results of BURINTEKH LLC bits with 3D cutters in the conditions of Eastern Siberia are shown.
