(54) УСТРОЙСТВО дл ловли КАБЕЛЯ(54) CABLE FISHING DEVICE
ЭЛЕКТРОПОГРУЖНОГО ЦЕНТРОБЕЖНОГО НАСОСА В СКВАЖИНЕELECTRIC SUBMERSIBLE CENTRIFUGAL PUMP IN WELL
Изобретение относитс к ремонту нефт ных скважин, а именно к устройствам дл ликвидации аварий с кабелем электропогруженного центробежного насоса (ЭЦН).The invention relates to the repair of oil wells, in particular, to devices for eliminating accidents with a cable of an electro-immersed centrifugal pump (ESP).
Известны инструменты дл ловли тартального каната и картонажного кабел , с помощью которых также производ т ловильные работы кабел ЭЩ, Эти инструменты представл ют собой ловильные удочки с шарнирными или приваренными крючками Cl3.Known tools for catching the starting rope and cardboard cable, with the help of which they also produce fishing works for the ESh cable. These tools are fishing rods with hinged or welded hooks Cl3.
Недостатком этих инструмен ов вл етс то, что процесс ловли носит за т жной и непроизводительный характер , так как при удочном захвате подъем аварийного кабел осуществл етс небольшими кусками. Кроме того дл захвата кабел ЭЦН, имеющего большую жесткость, его необходимо см ть (сжать) , т.е. получить в скважине массу аварийного кабеА . Это достит-аетс дополнительным спускомThe disadvantage of these tools is that the fishing process is tight and unproductive in nature, since with the catch grip the emergency cable is lifted in small pieces. In addition, in order to grip the ECP cable with greater rigidity, it must be squeezed (compressed), i.e. get in the well mass emergency cable. This comes with an additional descent.
в скважину печати или другого подобного инструмента.into a well print or other similar tool.
Наиболее близким по технической сущности к предлагаемому вл етс штопор ловильный СШЛ) , примен емый при электробурении дл ловли кабел , содержащий верхний переводник,корпус и узел захвати кабел , .выполненный в виде ловильной спирали с переменным шагом, жестко закрепленной в корпу10 се (23.The closest in technical essence to the present invention is a corkscrew catching SSL) used for electric drilling to catch a cable, containing a top sub, a housing and a cable pickup unit, made in the form of a fishing helix with a variable pitch fixed in the housing (23.
Недостатком известного инструмента вл етс то,что захват кабел осуществл етс не всегда, т.е. процесс также носит зат жной характер.A disadvantage of the known tool is that the cable is not always gripped, i.e. The process is also lengthy.
