Abstract
The utility model relates to a multi-functional gas recovery well head device for oil-gas field, which consists of a conical seat type tubing head 1, a tubing head reducing joint 2, an upper flange 3, a well head protection pipe nipple 4, a main valve 5, a four-way pipe 6, a overhead valve 7, wing valves 8 and 10, and a throttle valve 9. The upper flange 3 above the conical seat type tubing head 1 is provided with the well head protection pipe nipple 4. A cavity above the tubing head 1 is provided with the tubing head reducing joint 2, the upper end of which is connected with the well head protection pipe nipple 4 by screw thread. Two wing valves 10 are connected with and arranged on both sides of the conical seat type tubing head 1 respectively. The upper part of the upper flange 3 is connected with two main valves 5, which are connected with four-way pipe 6 on the upper part. Each side of the four-way pipe 6 is connected with a wing valve 10. A throttle valve 9 is arranged on the outer side of the wing valve 10. The overhead valve 7 is arranged above the four-way pipe 6. The well head device integrates the gas recovery production with the fracture treatment. In the fracture treatment, the well head protection pipe nipple could prevent the gas recovery well head device from the erosion of the fracture medium and prolong the service life.
Description
Technical field:
The utility model relates to a kind of wellhead assembly that is used for the natural gas in oil and gas fields exploitation, belongs to the oil gas production equipment class.
Background technology:
At present, the gas wellhead equipment of oil gas field field by using roughly has two kinds, and a kind of is only to be used for the gas production manufacturing process, need be replaced with fracture well head when carrying out the pressing crack construction operation, another kind then for dual-purpose be centralized procurement gas produce and fracturing work in one.The former is owing to need change operation, thereby the operating cost height, though the latter need not to change operation, the pressure break medium can cause very big erosion effect to well head when fracturing work, influences the application life of gas wellhead equipment.
Summary of the invention:
The purpose of this utility model is to provide a kind of centralized procurement gas and fracturing work pressure break medium when one also can guarantee fracturing work well head not to be had the multi-functional gas wellhead equipment of erosion.
The utility model is to realize like this.This kind wellhead assembly is made up of awl seat formula tubing head, tubing head reducing joint, upper flange, wellhead protecting pipe nipple, four-way, main valve, overhead-valve, flutter valve, choke valve; Be provided with the wellhead protecting pipe nipple in the upper flange of awl seat formula tubing head top, be provided with the tubing head reducing joint in the tubing head upper chambers, the reducing joint upper end is connected with screw thread with the wellhead protecting pipe nipple; Each tipping of both sides of awl seat formula tubing head has two flutter valves; The tipping of upper flange top has two main valves, and the tipping of main valve top has four-way; The four-way both sides respectively are hinged with a flutter valve, and a choke valve is equipped with in the flank valve outside, and the tipping of four-way top has overhead-valve.Gas recovery well wellhead assembly by above-mentioned assembling mode assembling can carry out normal gas production production under normal conditions.When carrying out the fracturing work construction; earlier main valve under this device is disassembled with top; connect the special-purpose tree-protector of fracturing work then; because the special-purpose tree-protector of pressure break directly is connected with the wellhead protecting pipe nipple of tubing head reducing joint top; the pressure break medium need not pass through wellhead assembly during fracturing work; but directly enter the down-hole by the tubing string that is suspended on the tubing head, do not reach the prolongation wellhead assembly purpose in application life thereby therefore well head is had erosion.
The production of the utility model centralized procurement gas and two kinds of functions of fracturing work are in one; during fracturing work; both can remove from and change the shaft mouth operation operation; can connect the special-purpose wellhead assembly of pressure break again when wherein having set up wellhead protecting pipe nipple fracturing work; make gas wellhead equipment avoid the erosion of pressure break medium, prolong the application life of wellhead assembly greatly.
Description of drawings:
Accompanying drawing is a general structure schematic diagram of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made up of awl seat formula tubing head 1, tubing head reducing joint 2, upper flange 3, wellhead protecting pipe nipple 4, main valve 5, four-way 6, overhead-valve 7, flutter valve 8,10, choke valve 9, its assembling, annexation are as follows: be provided with wellhead protecting pipe nipple 4 in the awl seat formula tubing head 1 top upper flange 3, be provided with tubing head reducing joint 2 in tubing head 1 upper chambers, reducing joint 2 upper ends and wellhead protecting pipe nipple 4 are to be threaded; Each tipping of 1 both sides of awl seat formula tubing head has two flutter valves 10; The tipping of upper flange 3 tops has two main valves 5, and the tipping of main valve 5 tops has four-way 6; Four-way 6 both sides respectively are hinged with a flutter valve 10, one flank valves 10 outsides one choke valve 9 are housed, and the tipping of four-way 6 tops has overhead-valve 7.Wherein, it is the flat gate valve of 103mm that two main valves 5 adopt latus rectum, and it is the wedge action valve of 65mm that overhead-valve 7 and flutter valve 8,10 adopt latus rectum.Choke valve 9 adopts the adjustable choke valve of JLK65-35 type.Tubing head reducing joint 2 top external diameters are less, and inner headed face is provided with and connects wellhead protecting pipe nipple 4 internal thread that is connected, in, the bottom periphery is tapered, match with awl seat formula tubing head 1 inner headed face.Wellhead protecting pipe nipple 4 periphery lower end screw threads and tubing head reducing joint 2 match.
