Description

Изобретение отиосите  к инструмепту дл  бурени  нефт ных л газовых екважин.The invention of the invention to the tool for drilling oil and gas wells.

Известно буровое шарошечное долото со сплошными кольцевыми нзносостойкныи вставными венцами, закренл емымн на шарои1ке с помощью найки.Known roller bit with solid annular nosnosostoyknyy inset crowns, fastened on a ball with nike.

С целью новышенн  надежности кренленп  венцов, нредлагаетс  нх выполн ть с внутренjiefi ко Г1 ческой поверхностью, у которой вершина конуса обрашена в сторону, противоноложн}ю вершине шарошки, контактируюшей с соответствую1цей конической поверхностью на теле шарошки, причем большнй диаметр конического по са на шарошке равен или MCHbHje меньшего диаметра конического по са на венце.In order to improve the reliability of liners, it is not necessary for them to perform with the inner surface a coherent surface with the top of the cone trimmed to the side, opposite the top of the roller cone contacting the corresponding conical surface on the body of the cone, and the large conical surface of the cone is equal to or MCHbHje of smaller diameter conic across sa at the crown.

На фиг. I изображена шарошка с венцами, нродольныи разрез; на фнг. 2 - то же, сечение но венцу.FIG. I shows a roller cutter with crowns, but at the incision; on fng. 2 - the same section, but the crown.

На шарошке выполнены кольцевые конические по ски /, причем вершины конусов, част ми которых  вл ютс  эти по ски, обращены в сторону, противоположную вершине шарошки . На по ски посажены сплошные износостойкие кольцевые венцы 2, имеющие внутренн еOn the roller cutter, annular conical ribs are made, and the tops of the cones, parts of which are these skins, are directed in the direction opposite to the vertex of the cone. A continuous wear-resistant ring rims 2, having an inner

Больший диаметр конического по ска на шарошке (/ш равен или меньше на величнну 0,1-0,3 М.Ч меньшего диаметра конического по сгса на венце ds.The larger diameter of the conical rim on the roller cutter (/ w is equal to or less by 0.1-0.3 M.Ch of a smaller diameter of the conic along the edge of the rim ds.

Пространство между шарошкой и венцом заполн ют самотвердеющнми матерпалами, выполн ющими роль замка, предотвращающего самопро;1звольиое сползание венцов с шарошки .The space between the roller cutter and the crown is filled with self-hardening materials, which play the role of a lock, preventing self-propelling, and the sliding of the crowns from the roller cutter.

Буровое шарошечное долото, включающее лапы и шарои ки со сплошными кольцевыми изиосостойкнми вставными венцами, отличающеес  тем, что, с целью повышени  надежности креплени  венцов, они выполнены с внутренне ко}П1ческой поверхностью, у которой вершина конуса обращена в сторону, прот шоположную вершине шарошки, контактирующей с соответствующей конической поверхностью на теле шарошки, причем больший диаметр конического по са на шарошке не больше меньшего диаметра конического по са fia веьце.Rolling bit chisel, including feet and sharoki with continuous annular izosostoyknym inset rims, characterized in that, in order to increase the reliability of fastening the rims, they are made with an internal surface with a cone apex facing the side, protruding from the apex of the cone, contacting with a corresponding conical surface on the body of the roller cutter, and the larger diameter of the conical over ca on the roller cone is not larger than the smaller diameter of the conical body.
