Description
3, насаженных на оси 4, перемещающиес в пазах 5. Стакан 6 поджимаетс к буртику корпуса пружиной 7. Через блок 8 перекинут капроновый трос 9. На передней части корпуса смонтированы направл ющие полозь 10.3 mounted on the axis 4, moving in the grooves 5. The cup 6 is pressed against the body shoulder by the spring 7. Through the block 8, a nylon cable 9 is slung. On the front part of the body, guide rails 10 are mounted.
При доставке с помощью щтанг распорного устройства в скважину на заданную глубину концы упоров 2 вставлены в стакан 6, поджимаемый пружиной 7 к буртику корпуса 1. Пружины 3 наход тс в сжатом состо нии и поджимают концы упоров к внутренней стенке стакана. По достижении распорным устройством заданной глубины к обоим концам троса 9 прикладываетс необходимое усилие . Это усилие через блок 8, ось которого расположена в отверсти х стакана 6, передаетс на стакан, и последний перемещаетс в сторону усть скважины, причем корпус 1 упираетс своим наконечником в штангу. Освободивщиес упоры 2 под действием пружин 3 распирают устройство в скважине, причем распор осуществл етс соответствующими зубцами упоров 2 в зависимости от диаметра скважины. Центровка устройства в скважине обеспечиваетс направл ющими полозь ми 10.Upon delivery with the help of a shtang spacer into the well to a predetermined depth, the ends of the stops 2 are inserted into the cup 6, pressed by the spring 7 to the collar of the body 1. The springs 3 are in a compressed state and press the ends of the stops to the inner wall of the cup. When the spacer reaches a given depth, the necessary force is applied to both ends of the cable 9. This force through the block 8, the axis of which is located in the holes of the cup 6, is transmitted to the glass, and the latter moves in the direction of the wellhead, with the housing 1 resting with its tip on the rod. The released stops 2 under the action of the springs 3 expand the device in the well, and the strut is made by the corresponding teeth of the stops 2 depending on the diameter of the well. The alignment of the device in the well is provided by the guide rails 10.
По окончании распора штанги, с помощью которых устройство было доставлено на заданную глубину, извлекаютс из скважины, а концы капронового троса зачаливают с двух сторон измерительной аппаратуры.At the end of the thrust, the rods with which the device was delivered to a predetermined depth are removed from the well, and the ends of the kapron cable are moored on both sides of the measuring equipment.
По окончании измерений или в случае необходимости к обоим концам троса прикладывают усилие, значительно большее, чем то, которое обеспечивает надежный распор устройства в скважине, вследствие чего сначала блок 8, а затем корпус 1 перемещаютс в сторону усть скважины, при этом оси 4 перемещаютс по пазам 5 и упоры 2 под действием пружин 3 складываютс в переднейAt the end of the measurements or, if necessary, a force much greater than that which ensures reliable device deployment in the well is applied to both ends of the cable, as a result of which the block 8 first and then the housing 1 moves towards the wellhead, while the axes 4 move along the grooves 5 and the stops 2 under the action of the springs 3 are folded in the front
части корпуса. После этого устройство легко извлекаетс из скважины.body parts. Thereafter, the device is easily removed from the well.
Предмет изобретени Subject invention
Распорное устройство дл проведени геофизических измерений в горизонтальных иA spreader for conducting geophysical measurements in horizontal and
слабонаклонных скважинах, содержащее корпус , подпружиненные упоры с ос ми, блок с тросом и направл ющие полозь , отличающеес тем, что, с целью повышени надежности распора и многократного использовани устройства, оно снабжено подпружиненным стаканом, в который вставлены концы упоров, а оси упоров установлены в пазах, выполненных в корпусе перпендикул рно его оси, причем концы упоров имеют несколькоweakly inclined wells, comprising a housing, spring-loaded stops with axles, a block with a cable and guides of a runner, characterized in that, in order to increase the reliability of spreading and repeated use of the device, it is equipped with a spring-loaded cup into which the ends of the stops are inserted, and the axes of the stops are installed in the grooves made in the housing perpendicular to its axis, with the ends of the stops having several
зубцов.teeth
