The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Referring to figs. 1 through Fig. 7, Wellhead offset apparatus of the present utility model comprises: top connection 1, be enclosed within the upper flange 2 in top connection 1, and lower contact 3, and be enclosed within the lower flange 4 in lower contact 3.Concrete, top connection 1 is cylindric, and top is for being connected with rubber gate (not shown), and the bottom outwardly convex is formed with flange card platform 5, and for blocking upper flange 2, the side of flange card platform 5 is arc-shaped curved surface; The structure of lower contact 3 is divided into two parts, and top is hemispherical, for the arc-shaped curved surface with flange card platform 5, docks, and it is cylindric that bottom is, for being connected with the little four-way of well head (not shown); Lower flange 4 is enclosed within the top of lower contact 3, and its medial surface is arc-shaped curved surface.
Below take top connection 1 internal diameter as 60mm is example, the utility model is described further.
The external diameter of the internal diameter of upper flange 2 and top connection 1 differs 2mm, and the internal diameter of upper flange 2 is 82mm, not only can guarantee to be enclosed within smoothly in top connection 1, and can guarantee that top connection 1 can significantly not rock in upper flange 2;
The negative camber radius on lower contact 3 tops equates with the subsequent corrosion of flange card platform 5, i.e. the negative camber radius on lower contact 3 tops is 50mm, so, when top connection 1 is docked with lower contact 3, can realize sphere deflection tuningout and sphere linear sealing; The positive camber radius on lower contact 3 tops is 60mm, and the bottom barrel bore is 60mm, with the internal diameter of top connection 1, is consistent;
The medial surface of lower flange 4 is arc-shaped curved surface, and its subsequent corrosion equals the positive camber radius on lower contact 3 tops, and the subsequent corrosion of the medial surface of lower flange 4 is 60mm.
For guaranteeing that lower flange 4 can entangle lower contact 3, (through hole in the middle of lower flange is from top to bottom more and more narrow for the maximum inner diameter of lower flange 4, diameter at the upper surface place is maximum inner diameter, diameter at the soffit place is minimum diameter) half be less than the positive camber radius on lower contact 3 tops, preferably differ 1mm, the maximum radius of lower flange 4 is 59mm.
As a kind of preferred scheme, the thickness of lower flange 4 is 20mm, and so, the least radius of lower flange 4 is 54mm.
As a kind of preferred scheme, the bottom of the top of top connection 1, lower contact 3 all is formed with 21/2 gas thread, conveniently with rubber gate, the little four-way of well head, is connected.
More preferably, top connection 1, lower contact 3 are rotary structure.
Wellhead offset apparatus of the present utility model, its using method is: the top of top connection 1 is connected with rubber gate (not shown) with 21/2 gas thread, the bottom of lower contact 3 is connected with the little four-way of 21/2 gas thread and well head (not shown), the upper flange 2 be enclosed within top connection 1 is connected with the lower flange 4 use bolts (not shown) on being enclosed within lower contact 3, thereby forms a Wellhead offset apparatus be connected with well head.Because inside has adopted sphere deflection tuningout and sphere linear sealing principle, outside to adopt flange sphere tuningout structure and to use parallel flange to carry out fastening, make the angle excursion of Wellhead offset apparatus of the present utility model be not less than 5 degree, the deflection distance is not less than 15mm, design pressure 16MPa, not only can effectively prevent the packing eccentric wear, improve packing application life, and the safe pressure can guarantee well-flushing the time, also can effectively reduce the crude oil loss simultaneously, prevent the pollution of the environment, improve the oil well management level.
The well head of device for adjusting deviation is installed, when adding the packing operation, first unclamp the set bolt between upper flange 2 and lower flange 4, make wellhead blowout-preventing box in relaxation state, due to movable zone being arranged, adding packing is to add very smoothly, after adding packing, the bolt between the fastening device for adjusting deviation upper flange 2 in diagonal angle and lower flange 4, make polished rod aim at all the time the centre position of blowout prevention box, prevent the well head leakage of oil caused because of the packing eccentric wear, prevented environment pollution.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
