Abstract
The utility model relates to a well head control mechanical device for an oil (gas) production well in the production of an oil field, particularly a thick oil hot production sleeve pipe head. The utility model belongs to a well head mechanical device for a petroleum drilling well. The upper end surface of a pressing cover (6) of the utility model and the upper end surface of a sealing joint (1) are in a horizontal plane, the pressing cover (6) is processed with a threaded hole matched with the bottom of an oil production well head, and the upper end surface of the sealing joint (1) is processed with a V-shaped sealing steel ring groove. The utility model can be directly connected with a flange arranged on the bottom of a production tree, and the utility model needs not change a joint. Because the upper end surface of the sealing joint (1) is processed with the V-shaped sealing steel ring groove, the seal of the flange arranged on the bottom of the production tree and the hot production sleeve pipe head can be ensured. The utility model can simplify the operating program of the well head by a structural design and can raise the sealing performance of the well head when steam is injected from the well head in later period.
Description
Technical field
The utility model relates to the well head control plant equipment of (gas) well that recovers the oil in the field produces, and particularly a kind of heavy crude heat extraction casing head belongs to oil drilling bank head machinery device.
Background technology
Because viscous crude is the viscosity height at normal temperatures, adopt the difficulty of conventional method exploitation big.For this reason, in the recovery process of viscous crude, need implantation temperature up to 300 ℃～350 ℃ superheated steam, be convenient to exploitation with the viscosity that reduces viscous crude.But also produced sleeve pipe thus and be subjected to the adverse effect of thermal stretching the later stage oil producing operation at high temperature action.Be subjected to the influence of thermal stretching for reducing sleeve pipe to oil producing operation, in thick oil thermal extraction completion process, special cementing, well-completing process have been adopted, and the employing heavy crude heat extraction casing head supporting with it, but flange cooperates problems such as blow-by with thermal extraction casing head top connection screw thread the thermal extraction casing head configuration aspects that adopts at present existence is connected inconvenience, production tree with well head at the bottom of.
Summary of the invention
The purpose of this utility model is to provide a kind of heavy crude heat extraction casing head, solve adopt at present that thermal extraction casing head exists is connected inconvenience, production tree with well head at the bottom of flange cooperate problems such as blow-by with thermal extraction casing head top connection screw thread.
The utility model is mainly by body 11, slip spider 7, built-in slips 8, alignment pin 2, guide peg 3, gland 6, sealing ring 4,5, " Yx " sealing ring 9 reaches and production string 12 joining seal nipples 1, by-pass connection 10 grades are partly formed, slips 8 adopts the built-in design of suspension type, slips 8 upper ends are equipped with guide peg 3, alignment pin 2 on the guide peg 3 hangs slips 8 and is positioned in the slip spider 7, gland 6 adopts thread connection with body 11, the outer step of seal nipple 1 is pressed on the interior step of gland 6, and the upper surface of gland 6 and seal nipple 1 upper surface are a horizontal plane; Gland 6 is processed with and the supporting screwed hole in production wellhead bottom; Seal nipple 1 upper surface is processed with " V " type ring gasket groove.
The upper surface of the utility model gland 6 and seal nipple 1 upper surface are a horizontal plane; Gland 6 is processed with and the supporting screwed hole in production wellhead bottom, can directly be connected with flange at the bottom of the production tree, need not crossover sub.Seal nipple 1 upper surface is processed with " V " type ring gasket groove, has guaranteed the sealing between the flange and thermal extraction casing head at the bottom of the production tree.The utility model by the said structure design simplification shaft mouth operation program, and improved the sealing performance of later stage steam injection well head greatly.
