Opposite on the double male joint inner wall to set there are two hanging platform rank is sat, described two seat hanging platform ranks are used for hanging metal pipe；In gold
Belong to pipe outer wall, two seats hanging platform ranks, form two flow-conveying grooves between double male joint inner wall, the fluid in oil pipe can lead to from flow-conveying groove
It crosses.
Described two settings for sitting hanging platform ranks mirror symmetry each other are on double male joint inner wall.
It is fan annular that described two seats, which hang step end face,.
The central angle of the fan ring is less than 180 degree.
Described two end faces for sitting hanging platform rank are located on the same virtual annulus.
The center of the virtual annulus is overlapped with the center of the double male joint inner cavity.
A method of cleaning oil recovery oil pipe is realized using double male joint of the present invention, comprising the steps of:
S1, double male joint top be threadably secured and connect with tubing hanger, the bottom of double male joint and oil pipe are solid by screw thread
Fixed connection；
S2, inside tubing hanger tripping in metal tube to oil pipe, heating cable is equipped in the metal tube；Metal tube seat hangs over double public affairs
On the seat hanging platform rank of pipe nipple；It is closed end that metal tube, which is located at one end in oil pipe, and one end that metal tube is located at outside tubing hanger is set
There is cable outlet；
S3, heating cable is powered on, generates thermal energy, melts the crude oil of cured knot in oil pipe by thermal conducting function.
Compared with prior art, the present invention can be when cleaning oil recovery oil pipe, for the internal gold for being equipped with heating cable
Belong to pipe and support is provided, reduce the endurance of tubing hanger, when clearing up the crude oil of cured knot in oil pipe, provides more safety and protect
Barrier.Present invention design is simple, easy to use, has good promotional value.
