Abstract
The utility model relates to an oilfield oil recovery well head device, in particular to a novel well head device of an oil pumping machine. The technical scheme is as follows: the novel well head device comprises a handwheel, a big four-way and an oil pipe head, wherein a three-way is connected on the oil pipe head, a rubber gate is mounted at the top part of the three-way, a thermal insulation housing is arranged on the outer side of the rubber gate, and thermal insulation materials are arranged in the thermal insulation housing; an insulating cavity is arranged in the three-way, heating resistance wires are wound in the insulating cavity, and a connecting plug which is connected with the heating resistance wires is mounted on the outer side of the three-way. The novel well head device has the benefits that a frozen Christmas tree can be connected with a power supply when production is restored, thereby thawing rapidly, avoiding the adoption of a mobile boiler for thawing, and saving a large number of resources.
Description
One, technical field:
The utility model relates to a kind of oil well mouth device, particularly a kind of new pumping unit wellhead assembly.
Two, background technology:
At present, the rod-pumped well production tree that use in the oil field generally is by big four, goes up lower flange, little four-way, rubber gate, packing box is housed on upper flange successively, and sitting in big four has tubing head, center to have polished rod to pass.This production tree all will be wrapped up antifreeze before the winter is gone in the oil field of northern area in every year with heat insulating material to production tree, to summer for sanitation and hygiene again with its dismounting.Grown that liquid will be frozen in the production tree time that oil well stops, when resuming production, must thaw, wasted ample resources with boiler car.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of new pumping unit wellhead assembly that can quick-thawing is provided.
Its technical scheme is: comprise handwheel, big four and tubing head, connect threeway on tubing head, the rubber gate is installed at the threeway top, and the outside of described rubber gate is provided with lagging casing, and heat insulating material is housed in the lagging casing; Be provided with the insulation cavity in the described threeway, twine heating resistance wire in the insulation cavity, the attachment plug that is connected with heating resistance wire is placed in the outside of threeway.
The beneficial effects of the utility model are: frozen production tree can connect power supply when resuming production, and quick-thawing has avoided the employing boiler car to thaw, and has saved ample resources.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: handwheel 1, threeway 2, big four 3, tubing head 4, heating resistance wire 5, attachment plug 6, lagging casing 7, rubber gate 8, insulation cavity 9.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: comprise handwheel 1, big four 3 and tubing head 4, connect threeway 2 on tubing head 4, rubber gate 8 is installed at the threeway top, and the outside of described rubber gate 8 is provided with lagging casing 7, in the lagging casing 7 heat insulating material is housed; Be provided with insulation cavity 9 in the described threeway 2, twine heating resistance wire 5 in the insulation cavity, the attachment plug 6 that is connected with heating resistance wire 5 is placed in the outside of threeway 2.Frozen production tree can connect power supply when resuming production, quick-thawing has avoided the employing boiler car to thaw, and has saved ample resources.
