Description
Известны мачты дл вертикального и наклонного бурени скважин , выполненные из основани , портала, основной фермы с подкосами и кронблока.Known masts for vertical and inclined drilling of wells, made of the base, portal, main truss with braces and crown block.
Однако такие мачты не приспособлены дл работы с трехструнной талевой оснасткой, котора повышает грузоподъемность лебедки на 30%, что особенно желательно в случае ликвидации аварий на буровой .However, these masts are not adapted to work with a three-stringed tackle equipment, which increases the winch loading capacity by 30%, which is especially desirable in case of liquidation of accidents at the rig.
Применение кронблока с перемещающимс роликом и выполнение кронблока в виде качающегос коромысла устран ет возможность возникновени неуравновешенных боковых усилий, разгружает мачту от поперечных изгибающих сил, исключает необходимость применени отт жного ролика.The use of a crown block with a moving roller and the execution of the crown block as a rocker arm eliminates the possibility of unbalanced lateral forces, unloads the mast from transverse bending forces, eliminates the need for a pull roller.
Монтаж основной фермы мачты на портале, который может одновременно служить и каркасом бурового сара , позвол ет более удобно оборудовать рабочие места дл бурени и сократить габариты сара за счет перемещаемой точки шарнирного креплени ствола мачты на портале .The installation of the main mast truss on the portal, which can simultaneously serve as the frame of the drill sar, makes it easier to equip workplaces for drilling and reduce the size of the sar due to the movable point of the hinged mount of the mast trunk on the portal.
На чертеже схематически изображена предлагаема мачта, в двух проекци х.The drawing shows schematically the proposed mast, in two projections.
На портале / щарнирно закреплен основной ствол 2 мачты, имеющий открытую переднюю грань. Внутри ствола 2 перемещаетс талевый блок 3. Подкосы 4 вверху имеют щаровые опоры, а внизу поворотные регулировочные винты. Угол наклона мачты устанавливают с помощью регулировочных винтов и откидной секции на подкосах.The main trunk of the 2 masts with an open front face is fixed on the portal / hinged. Inside the barrel 2, the traveling block 3 is moved. The struts 4 at the top have ball bearings, and at the bottom are pivoting adjustment screws. The angle of the mast is set using adjusting screws and a hinged section on the struts.
Дл более рационального размещени оборудовани внутри портала бурение ведут дл углов 75-90° с щарнира 5 и дл углов 60- 75° с щарнира 6.For a more rational placement of equipment inside the gantry, drilling is carried out for angles of 75-90 ° from joint 5 and for angles of 60- 75 ° from joint 6.
