Abstract
The invention discloses an oil well heating cable heated through a flexible skin effect and a short circuit. The cable comprises a cable body and a cone body, wherein the cable body comprises a conductor, a first insulating layer, a second insulating layer, a copper wire braiding layer and an armor layer sequentially from inside to outside, and the cone body is fixedly arranged at one end of the cable body and is connected with the conductor and the armor layer. The cone body is connected with the end portion of the cable body through a welding process and is located at the bottom of an oil well to enable the armor layer to be in short-circuit connection with the conductor, so that heating is achieved, and a pumping unit sucker rod is heated. By the aid of the oil well heating cable heated through the flexible skin effect and the short circuit, the flexibility and the abrasive resistance of an outer protective layer of the oil well heating cable can be improved, underground installation of products is facilitated, and service lives of products are prolonged.
Description
Technical field
The present invention relates to cable processing and manufacturing technical field, relate in particular to a kind of flexible kelvin effect and short circuit and add the hot oil wells heating cable.
Background technology
The oil well heating cable is oilfield applications oil pumper beam hanger heating cable, can solve the difficult problem of lot of domestic and international heavy crude well oil pumping.The present domestic oil well heating cable that all adopts metallic sheath and high temperature plastics sheath technology, because oil well depth is generally all between 2000 to 3000 meters, sucker rod is twitched the insulating barrier that is easy to cause heating cable up and down and is destroyed and cable is shortened useful life.
Summary of the invention
The purpose of this invention is to provide a kind of flexible kelvin effect and short circuit and add the hot oil wells heating cable, can improve flexibility and the outer jacket resistance to wear of oil well heating cable, be convenient to product and go into the well installation and the useful life of increase product.
Technical solution of the present invention is:
Flexible kelvin effect and short circuit add the hot oil wells heating cable, comprise line body and cone, described line body comprises conductor, insulating barrier one, insulating barrier two, copper wire braid, armour from the inside to the outside successively, and described cone is fixedly arranged on an end of described line body, and connects described conductor and armour.Described cone adopts welding procedure to connect online end of body and is positioned at the oil well bottom, and armour is connected with the conductor short circuit, thus heating and heating oil pumper beam hanger.
Add the hot oil wells heating cable as the further improved flexible kelvin effect of the present invention and short circuit, described conductor is that the soft core of multiply adds the steel core conductor.
Add the hot oil wells heating cable as the further improved flexible kelvin effect of the present invention and short circuit, described insulating barrier one is the polytetrafluoroethylene lapped insulation.
Add the hot oil wells heating cable as the further improved flexible kelvin effect of the present invention and short circuit, described insulating barrier two is the glass fibre lapped insulation.
Add the hot oil wells heating cable as the further improved flexible kelvin effect of the present invention and short circuit, described armour is steel wire multilayer armouring.
Flexible kelvin effect provided by the present invention and short circuit add the hot oil wells heating cable, the soft core of multiply adds the steel core conductor in adopting, wrapped and the glass fibre lapped insulation of additional ptfe, the copper wire braiding adds the high-power short circuit heating process that steel wire multilayer armouring produces kelvin effect, change flexibility and the outer jacket resistance to wear of cable, also be convenient to the product installation of going into the well; The flexible useful life that has also increased product simultaneously greatly of the resistance to wear of outer jacket and product.
