Description
Technical field
The present invention relates to a kind of fast traversing joint device of used for electric cable of electric pump oil extraction well mouth.
Background technology
The oil field is recovered the oil on-the-spot, along with several work such as drilling measuring, oil recovery all need to be equipped with cable joint, so that the instrument or the equipment of cable and down-hole is coupled together during operation.The existing outspoken speed of electric pump producing well of producing of China is passed through joint and existed following defective at present: what (1) sealing was adopted is non-metallic seal mode, the aging of product, corrosion-resistant, resistance to elevated temperatures is bad, cause well head sealing property instability, easily cause the potential safety hazard of blowout, shorten the useful life (generally be 5 years the useful life of this product) of product simultaneously.(2) at present the existing outspoken speed of electric pump producing well of producing of China cable seal mode of passing through joint is that a stuffing box is respectively arranged on tubing hanger and upper flange, directly seal by airtight and watertight padding and cable, cause the only suitable 2000V of this product, the following high-voltage motor power transmission mode of 150A uses down, the outspoken speed of domestic in addition electric pump producing well passes through that joint is the highest can only to bear the 14Mpa-103Mpa borehole pressure, the use of the ultradeep well powerful device that makes like this is restricted, and ensures as inadequate safe in utilization can not get.(3) adopt airtight and watertight padding and the direct sealing means of cable, installs very inconvenient, simultaneously the rubber skin of cable outer wrapping easily when the adding airtight and watertight padding because of pushing easy damaged, cause electric leakage hidden danger.
Summary of the invention
At the problems referred to above, the invention provides a kind of not only applied range, and security performance is good and easy for installation.
The present invention has adopted following technical scheme: a kind of fast traversing joint device of used for electric cable of electric pump oil extraction well mouth, it comprises joint body, joint body is a tubulose, the upper flange that joint body passes wellhead equipment from top to bottom successively is connected with tubing hanger with tubing hanger, between joint body and upper flange and the tubing hanger all for being sealed and matched, be provided with the top articulation at the top of joint body, be provided with the bottom joint in the bottom of joint body, cable is housed in joint body, the upper end of cable is connected with power supply by the top articulation, and the lower end is tightly connected by bottom joint and electric pump.
Described joint body is a stainless steel.What being sealed and matched between described joint body and upper flange and the tubing hanger adopted is metallic seal, being provided with sealing ring between upper flange and the joint body, is provided with lower seal between tubing hanger and joint body.The described sealing ring of going up is tapering metal o-ring I, and the described lower seal in circular arc position that is provided with projection in the outer conical surface of sealing ring I is tapering metal o-ring II, and the oil pipe four-way in the conical surface of sealing ring II and tubing hanger and the wellhead equipment is close to.The copper core of described cable is bonding by the vulcanization of rubber and joint body.Described joint body is connected by fastening screw nut with tubing hanger.
The invention has the beneficial effects as follows: what being sealed and matched between joint body of the present invention and upper flange and the tubing hanger adopted is metallic seal, metallic seal mainly contains up and down, and the tapering metal o-ring constitutes, what upper sealing gasket adopted is the arc position that processes projection on the inside and outside circle conical surface of last sealing ring, utilize the squeezing action of upper flange, boss homogeneous deformation on the outer conical surface, what the lower seal circle adopted is to stay certain precompressed amount in lower seal, utilize the deadweight of oil pipe, so not only have stronger anti-CO
2And H
2S is corrosion-resistant, and withstand voltage, anti-aging, corrosion-resistant, high temperature resistant, increase the service life (can use 10 years performances), and also sealingly secure is reliable, the seal easy installation and removal.Three cable copper cores of the present invention adopt the specific rubber sulfuration in joint body, and the top of cable is connected with power supply, and the bottom is connected with electric pump, so both can avoid the outer rubber damage of cable and cause electric leakage, can pass through 2000-5000V, 150 high-tension current again can be so that install.
