Description

РЬвестны комбинированные буровые пгарошечные долота, выполненные с лопаст ми между шарошек.Combined drill bits are made with blades between the sharoshek.

Предлагаемое шарошечное буровое долото отличаетс  от известных тем, что лопасти, расположенные между шарошками под большим углом к оси долота,  вл ютс  продолжением лопастей шнека, предназначенного дл  транспортировани  на поверхность разбуренной породы.The proposed roller drill bit differs from the known ones in that the blades located between the cones at a large angle to the axis of the bit are a continuation of the blades of the screw intended to be transported to the surface of the drilled rock.

На чертеже показано предлагаемое шарошечное долото.The drawing shows the proposed roller bit.

Долото предназначено дл  бурени  геологоразведочных скважин в засушливых районах, где затруднено снабжение водой буровых установок . Особенно пригодно предлагаемое долото дл  бурени  скважнн по твердым и крепким породам, в которых бурение с промывкой забо  водой или глинистым раствором затруднено, а бурение шнековым инструментом  вл етс  малопроизводительным.The bit is intended for drilling exploration wells in arid areas where it is difficult to supply drilling rigs with water. The proposed bit is particularly suitable for drilling boreholes for hard and hard formations, in which drilling with washing with mud or mud is difficult, and drilling with auger tool is inefficient.

Предлагаемое шарошечное долото с двум  шарошками типа Т выполнено с лопаст ми шнека между шарошками. Лопасти установлены под большим углом к оси долота и своими кромками подход т под шарошки и транспортируют па шнек бурового стана разбуренную породу.The proposed roller bit with two type T cones is made with auger blades between the cones. The blades are installed at a large angle to the axis of the bit and, with their edges, fit under the cones and transport the drilled rock to the auger of the drill mill.

В своем заключении Верхне-Сергинский машиностроительный завод рекомендует применение предлагаемого долота в засушливых районах.In its conclusion, the Verkhne-Serginsky machine-building plant recommends the use of the proposed chisel in arid areas.

Пред мет изобретени Present Invention

Шарошечное буровое долото с режушнми лопаст ми, отличаюш , еес   тем, что, в цел х обеспечени  удалени  выбуренной породы при отсутствии циркул ции промывочной жидкости, его лопасти расположены между шарошками и  вл ютс  продолжением спирали ,породоудал ющего пгнека.The rolling blades with cutting blades are distinguished by the fact that, in order to ensure the removal of cuttings in the absence of circulation of the washing liquid, its blades are located between the cutting stones and are a continuation of the spiral of rock-collecting PGne.
