Description
Affiliated technical field:
The utility model relates to a kind of device that is used for oil downhole electric pump cable protection; this device is installed in the downhole electric pump flange that respectively economizes on electricity between the pump accessory and connects the undergauge position; be mainly used in cable is fixed on the electric pump pipe column body; cable is not contacted with underground bushing, with the protection cable rise go into the well and equipment running process in injury-free.
Background technique:
At present; existing oil downhole electric pump cable protection device adopts steel disc bandage and break iron protection; the cable protection device of steel disc strap configurations; be cable and electric pump pipe column body to be bundled with steel band; steel band is inserted the bandage lock sleeve; clamp with special use is flat with the lock sleeve card, makes the engagement of lock sleeve and steel disc form the sawtooth pattern striped, and steel band is wrapped on oil pipe body and the cable.Said structure is through using for many years, and the main problem that exists is: steel disc intensity is low, connects poor reliability, in working the process of going into the well, with the sleeve friction fracture, and causes a large amount of steel discs well that falls, and can cause a large amount of article dropped in well.Simultaneously, because the coming off of steel disc bandage, make cable destructions that in the process of removing, is worn, cause cable to open circuit, forms a large amount of electric pump operations repeatedly, influence production.
The model utility content:
The utility model purpose provides a kind of downhole electric pump cable protection device, and the steel disc bandage bond strength that exists in the technology of solution Beijing is low, the problem of linkage structure poor reliability.
The technical solution of the utility model is: downhole electric pump cable protection device is installed in the undergauge position between the two economize on electricity pump line post bodies; comprise the protector watch box; anti-collision block and union body; the protector watch box; anti-collision block is an integral body; the cross section of protector watch box is a horse-saddle; just fall " U " shape; protected cable is placed in horse-saddle arc; protector watch box middle part be provided with and two economize on electricity pump line post bodies between the anti-collision block that is complementary of undergauge shape; the shape of union body also and the undergauge shapes between the two economize on electricity pump line post bodies be complementary, be connected by bolt between union body and watch box and the anti-collision block.
The connecting piece of protector is embedded in two undergauges that economize on electricity between the pump line post bodies, and connecting piece two these body diameters of economize on electricity pump line post are identical; The protector watch box is pressed in cable in the watch box groove, just in horse-saddle arc, and with the watch box cross-pressure on two economize on electricity pump line post bodies up and down; With bolt connecting piece and watch box are tightened connection, and the bolt place of lifting one's head is pounded flat, make the bolt end by riveting on watch box, prevent from that bolt vibration from moving back to buckle.
The anti-collision block that the watch box middle part of protection cable is provided with; be complementary with undergauge well width and undergauge; form two eccentric gardens by anti-collision block and watch box body, make the anti-collision block of watch box all ensconce when mounted in the undergauge groove, watch box body projection is on two joint pump line post bodies.
Adopt the utility model, protected cable is protected in the watch box wire way with watch box, and with bolt watch box and connecting piece is linked together.By the pretension of bolt, make the whole protecting device be fixed on the undergauge place between the two economize on electricity pump line post bodies firmly, and cable is wrapped on the two economize on electricity pump line post bodies.The utility model has made full use of the undergauge space between the two economize on electricity pump line posts, makes protector can adopt thick-wall tube processing, and the thickness and the intensity of watch box have obtained reinforcement, connect to adopt bolt to connect.Because adopt described structure, protector intensity reaches 100 tons of shock resistances, wear-resisting property can guarantee to rub 10 times no significant change continuously on 3000 meters casing wall.
The utility model is because simple in structure, and the manufacture cycle obtains shortening, and production process is few, more helps the quality monitoring to product; Can on present down electric pump basis, respective sleeve not being had specific (special) requirements, to 4 " electric pump is lowered to 51/2 " sleeve pipe do not have influence.Because easily damaged parts is a connecting bolt, other parts are not fragile, so the cable protection device can be used repeatedly, only need to change connecting bolt and get final product, and reduced user's user cost.
The utility model can be made the downhole electric pump cable protection device of different size according to the difformity of electric pump pipe column body different-diameter and undergauge, satisfies the needs of field produces.
