Abstract
The utility model relates to an adjustable oil extraction well head apparatus which is composed of cross joints, an oil pipe hanger, a flange gland and a universal light rod stuffing box. The utility model is characterized in that O-shaped sealing rings are installed on the external cylindrical surface, the external conical surface and the upper end surface of the oil pipe hanger. Rectangular screw bolt through holes are arranged on the flange gland. The lower end of the universal light rod stuffing box presents a spherical structure. The utility model has the advantages that the big cross joint and the small cross joint are integrated into a whole body, which reduces the height of the well head apparatus. The relative position of the light rod stuffing box and a light rod can be optionally adjusted and the structure is simple and compact, and the utility model is convenient to operate on site and provides great convenience for the installation of an oil pumping unit. The utility model is suitable for the well head apparatus of a walking beam oil pumping unit of the oil field and an oil extracting pump with a single screw rod.
Description
The utility model belongs to wellhead for production, particularly a kind of wellhead assembly that is used for oil field beam-pumping unit and single screw rod oil extraction pump.
At present, wellhead assembly commonly used, form by big four, little four-way, tubing hanger, because the nonadjustable form of rigidity is all adopted in wellhead assembly connection everywhere, so when the on-the-spot installation of oil pumper, be difficult to guarantee the axiality of polished rod and wellhead assembly, thereby cause that polished rod departs from the well head packing, cause the crude oil leakage; Existing wellhead assembly adopts the structure of a little four-way of stack on big four usually, and is bulky, both expended great deal of steel, is not easy to execute-in-place again and uses.
The purpose of this utility model is, designs and produces a kind of adjustable wellhead for production, the horizontal movement by regulating the flange gland and the elevation angle of polished rod stuffing box, be convenient to oil pumper installation, guarantee the axiality of polished rod and wellhead assembly.
Adjustable wellhead for production of the present utility model, by four-way, boll-weevil hanger, flange gland and universal polished rod stuffing box are formed, and the other hole that the four-way inboard has the band oblique angle communicates with the right side runner; Boll-weevil hanger is installed in the big four, and the flange gland connects with four-way mutually by gland bolt, it is characterized in that, on the external cylindrical surface of boll-weevil hanger lower end O-ring seals is housed, on the outer conical surface of upper end red copper ring and O-ring seals are housed, O-ring seals is equipped with in the upper surface, and the middle part has through hole; Have the rectangle bolt hole on the flange gland, its size is greater than the screw diameter of gland bolt; Universal polished rod stuffing box is loaded on flange gland top, its lower end structure spherical in shape, and this spheroid and packing cassette holder constitute sealing pair.
Using method of the present utility model is, during operation, following oil pipe is to the shaft bottom, and tubing hanger upper end and boll-weevil hanger link, and by O-ring seals and red copper ring, oil pipe inlet channel and oil jacket annular space chamber turnover runner isolated separate; Unclamp gland bolt, the flange gland can be done horizontal movement; Unclamp the packing box gland, universal polished rod stuffing box can be adjusted the elevation angle, therefore, need not adjust the basis of oil pumper, just can regulate the relative position of universal polished rod seal box and polished rod.
The utility model has the advantages that two combine into one to adopt big or small four-way, reduced the height of wellhead assembly, can regulate the relative position of polished rod stuffing box and polished rod arbitrarily, simple in structure, compactness makes things convenient for execute-in-place, for the installation of oil pumper provides very big convenience.Be applicable to the wellhead assembly of oil field walking beam oil production machine and single screw rod oil extraction pump.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of adjustable wellhead for production
As seen from the figure, adjustable wellhead for production of the present utility model, by four-way, boll-weevil hanger, flange bonnet and universal polished rod stuffing box are formed, and the other hole 4 that the four-way inboard has the band oblique angle communicates with right side runner 6; Boll-weevil hanger 2 is installed in the big four, on the external cylindrical surface of boll-weevil hanger lower end O-ring seals 5 is housed, on the outer conical surface of upper end red copper ring 7 and O-ring seals 8 and red copper ring 9 are housed, the middle part has through hole 3, and O-ring seals 10 that the upper surface is adorned and flange gland 11 constitute sealing pair; Flange gland 11 connects with four-way 1 mutually by gland bolt 16, has rectangle bolt hole 17 on the flange gland 11, and its size is greater than the screw diameter of gland bolt; Packing cassette holder 13 links by rubber gate 12 and flange gland 11, and universal polished rod stuffing box 14 is housed in the packing cassette holder 13, universal polished rod stuffing box lower end structure spherical in shape, and this spheroid and packing cassette holder 13 constitute sealing pair.In the universal polished rod stuffing box packing filling is housed, packing box gland 15 links by screw thread and packing cassette holder 13; Have oil pipe turnover runner 18 on the four-way.
