Abstract
The invention discloses an electric submersible pump wellhead cable outgoing structure, which comprises a wellhead, a casing cross joint, a cable sealing member, a cable and a cable guiding device, and is characterized in that the end part of the wellhead forms a wellhead flange; the bottom of the casing cross joint is connected to the wellhead flange, and two sides of the casing cross joint are provided with a casing valve; the cable sealing member is arranged an external opening of the casing valve at one side; and one end of the cable extends into the wellhead, and the other end of the cable goes out from the cable sealing member. Compared with the prior art, the electric submersible pump wellhead cable outgoing structure has the beneficial effects that firstly, the cable goes out from the casing valve in the cable outgoing structure, peeling processing is not required to be performed, corrosion of an air flow for the cable is reduced at the same time, and the breakdown failure rate of the cable is reduced; and secondly, the cable outgoing structure further comprises a guide wheel and a protection plate, wherein the guide wheel helps the cable to pass through the sealing member, damages imposed on the cable skin by bending is reduced, the protection plate protects the cable skin from being scratched when a mandrel hanger is arranged, and both the guide wheel and the protection plate play a role of reducing the breakdown failure rate of the cable.
Description
Technical field
The present invention relates to field of petroleum exploitation, and in particular to a kind of oil-submersible electric pump cable passes structure.
Background technology
The cable of traditional submerged electric oil pump well is passed from the top of four-way junction of casing, and is sealed after peeling, and the problem for existing now is that cable breakdown phenomenon occurs in the lower end market of tubing hanger, and fault rate accounts for more than the 10% of pump detection and workover, had a strong impact on oil output.By analysis, following reason causes cable breakdown：First, traditional structural cable needs the cable after peeling, peeling to be exactly at sleeve valve, the oil well higher for gassiness, is encroached on by washing away for a long time for air-flow, and peeling Job Operations are improper in addition, easily leave weak spot, become breakdown point；When the 2nd, transferring tubing hanger, scratch cable forms weak spot, becomes breakdown point.
The content of the invention
It is an object of the invention to：A kind of low oil-submersible electric pump cable of cable breakdown fault rate is provided and passes structure.
The present invention is achieved by the following technical solutions：A kind of oil-submersible electric pump cable passes structure, including：
Well head：Its end forms wellhead flange；
Four-way junction of casing：Its bottom is connected to wellhead flange, and its both sides is formed with sleeve valve；
Cable seal：Which is located at the collar extension of wherein side sleeve valve；
Cable：Its one end stretches into well head, and the other end is passed from cable seal；
Cable guide structures：The sleeve valve internal orifice of side is passed located at cable；
The cable guide structures include：
Support：Which is fixed in four-way junction of casing；
Guide wheel：On the bracket, the cable bypasses wheel face thereon for its flexible connection.
As further preferred version, also including protective board, the side guide wheel wheel face which is fixed on support and covering cable is passed through.
As further preferred version, the concave circular arc in the cross section of the guide wheel wheel face.
As further preferred version, also it is used to fix cable including some cable fixing clamp/clips.
Compared with prior art, the invention has the advantages that：
First, cable of the invention passes structure, and cable is passed from sleeve valve, processes without the need for peeling again, proposes the erosion flowed to cable with having reduced, reduces cable breakdown fault rate.
2nd, cable of the invention passes structure; also include guide wheel and backplate, guide wheel helps cable to pass through sealing member, injury of the less bending to cable skin; backplate protects cable skin not to be scraped off when tubing hanger is transferred, and all serving reduces the effect of cable breakdown fault rate.
