Description

Изобретение относитс к породоразру- шающему буровому инструменту и может быть использовано в нефтегазодобывающей промышленности при бурении скважин . The invention relates to a drilling tool porodorazru- depleting and can be used in the oil and gas industry for drilling wells.

Целью изобретени вл етс повышение эффективности долота путем обеспечени равнонагруженности вооружени всех венцов. The aim of the invention is to improve the efficiency by providing a bit ravnonagruzhennosti armed all rims.

На фиг. FIG. 1 показано буровое шарошечное долото; 1 shows a roller bit drill; на фиг. FIG. 2 - венцы одной шарошки; 2 - crowns one cutter; на фиг. FIG. 3-5 - схема расположени зубьев на венцах. 3-5 - Arrangement of the teeth on the crown.

Устройство состоит из корпуса 1 с лапами 2, на опорах 3 которых расположены шарошки 4 с размещенными на них зубчатыми венцами 5 - 7 по схеме самоочищени . The apparatus consists of a housing 1 with legs 2, on supports 3 which are located cutters 4 are arranged on the ring gears 5 - 7 for self-cleaning scheme. На фиг. FIG. 2 изображена шарошка с основными 5, центральными 6 и периферийными 7 зубчатыми венцами, средние рассто ни которых от оси долота 8 соответственно равны Rm(l), Rm(H), Rm(IH). 2 shows the basic cone 5, the central 6 and peripheral 7 toothed crowns, whose average distance from the bit axis 8 respectively Rm (l), Rm (H), Rm (IH). Шаги зубьев 9 основного венца 5 tm{l) показаны на фиг. Steps teeth 9 of the main ring 5 tm {l) shown in FIG. 4, центрального 6tj(l)-Ha фиг. 4, the central 6tj (l) -Ha FIG. 3. периферийного 7 tn(l) - на фиг. 3. Peripheral 7 tn (l) - Fig. 5. five.

Буровое шарошечное долото работает следующим образом. Drilling rock bit is as follows.

При вращении долота 8 вокруг своей оси шарошки 4, враща сь вокруг своих осей, перекатываютс по забою и разрушают зубь ми 9 своих венцов породу. If bit 8 rotates about its cone axis 4, while rotating around their axes, perekatyvayuts slaughter and destroy teeth 9 breed their rims. При этом разрушение породы на кольцевых забо х скважины осуществл етс отдельными венцами смежных шарошек. Thus failure of the rock in the well's annular slaughtering is effected by separate rims of adjacent cones.

Порода на периферии и в центре забо скважины разрушаетс соответственно зубь ми периферийных 7 и центральных 6 венцов, а промежуточна область забо скважины на смежных кольцевых забо х - основными 5 венцами смежных шарошек. Breed at the periphery and at the center respectively degraded downhole peripheral teeth 7 and central rims 6, and the intermediate region downhole on adjacent ring slaughtering x - 5 major crowns of adjacent cones. При этом интенсивность разрушени периферийной и центральной областей забо скважины задаетс отношени ми рассто ний венцов шарошек от оси долота к шагу The intensity degradation peripheral and central regions is set downhole ratios of distances rims cutters from the bit axis to step

зубьев выше по сравнению с центральной областью. teeth higher than the central region. Поэтому скорость углубки будет определ тьс интенсивностью разрушени горной породы на промежуточной области, Therefore uglubki speed will be determined by the intensity of breaking rock in the intermediate region,

перекрываемой основными венцами 5. Вследствие этого основна нагрузка от реактивных сил со стороны забо скважины приходитс на эти венцы. overlapped major crowns 5. As a result, the main burden of the reactive forces from the bottom of the well being attributable to these crowns. Но отношени рассто ний основных венцов шарошек от But the ratio of the distances from the main rims cones

оси долота к шагу зубьев этих венцов, однозначно определ ющие интенсивность разрушени породы или скорость углубки основных венцов смежных шарошек, заданы равными. bit axis to the tooth pitch of these rims, uniquely defining the intensity or breaking rocks speed uglubki main rims of adjacent cutters, set equal. Поэтому в процессе бурени Therefore, in the process of drilling

реактивные нагрузки со стороны забо будут распредел тьс между смежными шарошками равномерно. reactive loads from the slaughtering will be distributed uniformly between adjacent cones. Это обеспечивает увеличение долговечности опор смежных шарошек и их вооружени . This provides increased durability of poles of adjacent cutters and their weapons.

Равномерна скорость углубки смежных шарошек позвол ет стабилизировать долото относительно своей оси, вследствие чего уменьшаетс искривление скважин, а также повышает долговечность шарошечного долота. Uniform speed uglubki adjacent cones allows to stabilize the bit about its axis, thereby reducing the curvature of the wells, and increases durability rock bit.
