Abstract
The utility model relates to a cable device in a paraffin high pressure cementing hole top, which is characterized in that the cable device in a paraffin high pressure cementing hole top also comprises a body (3), a compressed sealing gum component (2), and a compressed head (4) of a sealing gum component, wherein both ends of the body (3) are small; the middle of the body is provided with a large hollow structure; the hollow structure in the body can form a paraffin storing cavity (7); the front end of the body (3) is provided with an external screw which is connected with a hole top threaded joint (1); the tail end of the body is provided with an external thread which is connected with the compressed head (4) of a sealing gum component (4); the middle end of the body is fixed with a pressurizing path (5) which is filled with paraffin; a pressurizing top thread (6) is fixed onto the upper end of the path, and the path is communicated with the paraffin storing cavity (7). The device can cause the paraffin to penetrate into steel wires of armoured cables under the high-pressure state; insulation layers of cable core wires are cemented with gaps, and the utility model can efficiently seal the pressure measuring cable at the hole top.
Description
Technical field:
The utility model relates to well head cable sealing device used on the oil field development field.Especially relate to a kind of oil well pressure measurement cable well head static seal device.
Background technology:
In oilfield development process, some oil well needs long-term formation testing pressure.With direct reading electronic gauge monitoring strata pressure the time, the signal cable line is at the poor sealing of well head, it is an insoluble technical problem always, because compression seal glue spare comes the sealing signal cable come what may, can not solve between the armour skin steel wire of armoured cable and the pressure permeation in slit between the steel wire mean terms line cable insulation.So leaking the pressure problem, the sealing of pressure measurement cable well head fails effectively to be solved always.
The utility model content:
There is not device can effectively solve the deficiency that the pressure problem is leaked in the sealing of pressure measurement cable well head in the prior art in order to overcome, the utility model provides a kind of paraffin height to press solidly shut-in well mouthful cable unit, this device can make paraffin under high pressure conditions, solid joint seal crack between the steel wire of infiltration armoured cable, the cable core insulating barrier is effectively at well head sealing pressure measurement cable.
The technical solution of the utility model is: this kind paraffin height presses solidly shut-in well mouthful cable unit, comprise well head threaded joint, body, compression seal glue spare and fluid sealant spare compressing head, this body is a hollow structure small in ends, broad in the middle, hollow structure in it forms a paraffin storage chamber, the front end of body has the external screw thread that is connected with the well head threaded joint, tail end has the internal thread that is connected with fluid sealant spare compressing head, end is fixed with a perfusion paraffin and a pressurization passageway therebetween, the pressurization jackscrew is fixed in this passage upper end, and this passage communicates with the paraffin storage chamber.
In addition, for monitoring institute's applied pressure at any time, can a Pressure gauge be installed in the intermediate ends of body, this Pressure gauge is fixed on the body, and its pressure chamber communicates with intrinsic paraffin storage chamber.
The utlity model has following beneficial effect: because the paraffin height presses solidly the interior paraffin chamber of sealing slit between cable for high pressure paraffin admittedly of the body of shut-in well mouthful cable unit, this cavity and paraffin perfusion, pressure-producing part links to each other, and the body two ends all have the parts of glue spare compression seal cable outer end separately, so the body two ends of passing through at cable have tentatively sealed the pressure measurement cable, inject in the annular seal space by the pouring member on the body with dissolving liquid paraffin then, high-pressure makes the armour skin of pressure measurement cable, steel wire, between and phase line between the slit be full of the liquid paraffin after coagulation, thereby make the excellent sealing of pressure measurement cable at well head.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-well head threaded joint among the figure, 2-compression seal glue spare, 3-body, 4-fluid sealant spare compressing head, 5-perfusion paraffin and pressurization passageway, the 6-jackscrew that pressurizes, 7-paraffin storage chamber, 8-well head pressure measurement cable, 9-Pressure gauge.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind paraffin height presses solidly shut-in well mouthful cable unit, comprise well head threaded joint 1, body 3, compression seal glue spare 2, fluid sealant spare compressing head 4, this body 3 is a hollow structure small in ends, broad in the middle, and the hollow structure in it forms paraffin storage chamber 7.The front end of body 3 has the external screw thread that is connected with well head threaded joint 1, tail end has the internal thread that is connected with fluid sealant spare compressing head 4, end is fixed with a perfusion paraffin and a pressurization passageway 5 therebetween, pressurization jackscrew 6 is fixed in this passage upper end, this passage communicates with paraffin storage chamber 7, is sealed attachment between perfusion paraffin and pressurization passageway 5 and body 3 and the pressurization jackscrew 6.
In addition, for monitoring the pressurization situation at any time, can increase a Pressure gauge 9 in described device, this Pressure gauge 9 is fixed in the intermediate ends of body 3, and the paraffin storage chamber in its pressure chamber and the body 3 communicates.
During actual the use, with well head pressure measurement cable 8, from well head threaded joint 1, compression seal glue spare 2, body 3, fluid sealant spare compressing head 4 passes successively.Tighten the outer end that screw thread makes compression seal glue spare 2 sealing pressure measurement cables 8; By perfusion paraffin and pressurization passageway 5, will fill with liquid paraffin in the paraffin storage chamber 7, precession pressurization jackscrew 6 is given the pressurization of the liquid paraffins in the paraffin storage chamber 7 then, thereby can penetrate into slit between the item of the armour skin steel wire of pressure measurement cable and core insulation layer.In the process of in giving paraffin chamber 7, pressurizeing, can observe its force value by Pressure gauge 9, treat that liquid paraffin solidifies after, just can seal well head pressure measurement cable well.
Claims (2)
1, a kind of paraffin height presses solidly shut-in well mouthful cable unit, comprise well head threaded joint (1), it is characterized in that: described device also comprises a body (3), compression seal glue spare (2), fluid sealant spare compressing head (4), this body (3) is small in ends, hollow structure broad in the middle, hollow structure in it forms paraffin storage chamber (7), body (3) front end has the external screw thread that is connected with well head threaded joint (1), tail end has the internal thread that is connected with fluid sealant spare compressing head (4), end is fixed with a perfusion paraffin and a pressurization passageway (5) therebetween, pressurization jackscrew (6) is fixed in this passage upper end, and this passage communicates with paraffin storage chamber (7).
