(54) САМОЛАЗ(54) DYNAMICS

1one

Изобретение относитс к геофизическим исследовани м и может быть использовано дл доставки средств измерени и других устройств в ствол скважин.The invention relates to geophysical surveys and can be used to deliver measuring instruments and other devices to the well bore.

Известно самоходное устройство, содержащее корпус и ведущие колеса с электроприводом 1.Known self-propelled device comprising a housing and drive wheels with electric drive 1.

Известен также самолаз, содержащий корпус и распорные плащки, которые привод тс в движение электродвигателем через кинематическую передачу 2.Also known is a self-propelled vehicle comprising a housing and spacers that are driven by an electric motor through a kinematic transmission 2.

Недостатком этого устройства вл етс низка скор.ость перемещени в скважине и незначительное т говое усилие.A disadvantage of this device is the low movement speed in the well and a slight pulling force.

Кроме того, самолаз содержит большое количество деталей и узлов, сложные блоки коммутации и управлени движением, что снижает его надежность работы в глубоких пологонаклонных скважинах.In addition, the self-propelled vehicle contains a large number of parts and components, complex switching and motion control units, which reduces its reliability in deep, inclined wells.

Цель изобретени - увеличение скорости перемещени и т гового усили в пологонаклонных скважинах.The purpose of the invention is to increase the speed of movement and pulling force in gently sloping wells.

Поставленна цель достигаетс тем, что самолаз снабжен солиноидом с двум сердечниками , подпружиненными т гами и электромагнитным вибратором с корем, причем корь установлен внутри сердечников и шарнирао св зан с передними распорными плашками , при этом сердечники соединены с подпружиненными т гами, одни из которых св заны с передними распорными плашками, а другие - с задними распорными плащка .ми, а корь и сердечники размещены с возможностью перемещени вдоль продольнойThe goal is achieved by the fact that the self-propelled machine is equipped with a two-core soloid with spring-loaded rods and an electromagnetic vibrator with a crust, the measles being installed inside the cores and the hinge is connected to the front expansion dies, while the cores are connected to spring-loaded rods, one of which is connected with the front dies, and others with the rear dorsal plates, and the measles and cores can be moved along the longitudinal

оси соленоида.solenoid axis.

На чертеже приведен самолаз, продольный разрез.The drawing shows samoAZ, longitudinal section.

Самолаз состоит из корпуса 1 и электромагнитного вибратора, содержащего сердечник 2, обмотку 3 и корь 4, который проходит сквозь амортизатор 5, сердечники б и соленоид 7. На одном конце кор 4 шарнирно закреплены распорные плашки 8, раскрывающиес с помощью пружин 9. НаSamolaz consists of a housing 1 and an electromagnetic vibrator containing core 2, winding 3 and measles 4, which passes through shock absorber 5, cores b and solenoid 7. At one end of the core 4, spacer plates 8, hinged by springs 9, are hinged.

корпусе 1 шарнирно закреплены распорные гглащки 10, раскрывающиес с помощью пружин 11. Распорные плащки 8 соединены с сердечником 6 т гами 12 и 13. По обе стороны от соленоида 7 расположены фик-саторы 14. К устройству подключен трехжильный кабель, имеющий на конце 3-х полюсную вилку.The casing 1 is hinged by spacer housings 10, opening up with the help of springs 11. The spacers 8 are connected to the core 6 tons 12 and 13. On either side of the solenoid 7 are the fixtures 14. A three-core cable is connected to the device. x pole plug.

Claims

The movement of the samolaz into the well is carried out as follows. The device is inserted into the well. Due to the springs 9 and 11, the spacer plates 8 and) 0 are pressed against the walls of the well. Before the current enters the winding 3, the bark 4 is 6–10 mm from core 2. A single-phase alternating current with a frequency of 50 or 100 Hz is supplied to the winding 3 of the electromagnetic vibrator. Anchor 4 and core 2 are mutually attracted to each other. The anchor cannot move to the left side, therefore core 2 is attracted to it along with housing 1. In the absence of current in the winding 3, the shock absorber 5 returns the measles 4, and with it the dies 8 to the original position, as the measles with the dies move to the right distance 6-10 mm. The cycle is repeated 50 or 100 times per second, depending on the power supply circuit, and the entire device moves to the right, into the well. The device works normally with a clearance between the core and core of 3-5 mm, the speed of movement of the entire device reaches 1000-1500 m / h. If necessary, to remove the device from the well, the voltage is applied to the solenoid 7. At the same time, the cores are included in the solenoid 7 and with the help of tg 12 and 13, the expansion plates, ki 8 and 10 are inserted into the housing 1, which stop using clamps 14. The coil // 10 12/4 - / bel on the winch, the samolez is removed from the well. The use of the device allows to increase labor productivity and reduce the cost of conducting geophysical surveys in gently sloping wells. The invention of the Samolaz, comprising a body and rear and front spacers, is distinguished by the fact that, in order to increase the speed of movement by increasing the traction force, it is equipped with a two-core solenoid, spring-loaded drafts and an electromagnetic vibrator with a cortex, with measles installed inside cores and is pivotally connected to the front spacer dies, while the cores are connected to spring-loaded rods, some of which are connected to the front spacer shrouds, while others are connected to the rear spacer dies The measles and cores are placed with the possibility of movement along the longitudinal axis of the solenoid.
