Abstract
1. Коронка терморезцовая с герметизатором забоя для бурения скважин различного целевого назначения, включающая корпус с корончатым кольцом, разделенным промывочными каналами на сектора-герметизаторы забоя, промывочные каналы и самозатачивающиеся резцы из сверхтвердых термоизносостойких материалов, лезвия которых образуют общую плоскость, параллельную с плоскостью торца коронки, отличающаяся тем, что резцы установлены на корончатом кольце спереди его так, что плоскость лезвия резцов совпадает или ниже плоскости торца коронки на глубину износа секторов-герметизаторов в период заточки коронки. ! 2. Буровая коронка по п.1, отличающаяся тем, что сектора-герметизаторы выполнены из термостойкого материала с коэффициентом теплопроводности меньшим, чем теплопроводность корпуса коронки ! 3. Буровая коронка по п.1 или 2, отличающаяся тем, что нижняя часть корпуса коронки выполнена с кольцевой выемкой по наружному и внутреннему диаметру с возможностью размещения в этих выемках гидро- и теплоизолирующих элементов, причем в качестве материала корончатого кольца использован материал с высоким пределом прочности, например, мартенситно-стареющая сталь. 1. Thermo-cutter crown with a face sealant for drilling wells for various purposes, including a housing with a crown ring divided by washing channels into face sealants, washing channels and self-sharpening cutters made of superhard heat-resistant materials, the blades of which form a common plane parallel to the plane of the crown end face characterized in that the cutters are mounted on the crown ring in front of it so that the plane of the blade of the cutters coincides or is lower than the plane of the end face of the crown wear well-sealers sectors during the sharpening of the crown. ! 2. The drill bit according to claim 1, characterized in that the sealing sectors are made of heat-resistant material with a thermal conductivity coefficient lower than the thermal conductivity of the crown body! 3. The drill bit according to claim 1 or 2, characterized in that the lower part of the crown body is made with an annular recess along the outer and inner diameter with the possibility of placing hydro- and heat-insulating elements in these recesses, and a material with high tensile strength, for example, maraging steel.
