Abstract
The utility model relates to a gas producing wellhead assembly; a lower flange is connected with a gas well casing pipe; a large four-way is installed on the lower flange; two sides of the large four-way are provided with a left casing pipe valve and a right casing pipe valve; the right end of the right casing pipe valve is provided with a plug, and the left end of the left casing pipe valve is provided with a casing pipe pressure display device; an upper flange is arranged above the large four-way, and provided with a standby valve on which a production valve is arranged, and a small four-valve is positioned on the production valve; the small four-way is provided with an oil pipe pressure display device; the left side of the small four-way is provided with a left control valve, the left side of which is provided with a left throttle valve; and the right side of the small four-way is provided with a right control valve, the right side of which is provided with a right throttle valve. The gas producing wellhead assembly has simple structure, fewer parts, light weight, low processing cost as well as convenient carrying and installation, is time-saving and labor-saving, saves cost, is convenient for use, leads a gas well to be opened earlier, and has remarkable economic benefits.
Description
Technical field
The equipment of well head control flow was a kind of gas wellhead equipment when the utility model was the gas production of a kind of oil field.
Background technology
Existing gas wellhead equipment complex structure, volume is big, the cost of production height, the carrying and installation time is long, and used haulage device expense height only is applicable to the gas well of hyperpressure, and when on the gas well of most of usual pressure, using existing gas wellhead equipment, cause the equipment waste, the set-up time, the long gas well production time that makes reduced, and reduced the gas well economic benefit.
Summary of the invention
The purpose of this utility model is a kind of gas wellhead equipment of design, and the gas well that is adapted at usual pressure uses, and simple in structure, cost is low, reduces the gas well investment.
The purpose of this utility model is achieved in that by left choke valve, left side control valve, the tubing pressure display unit, little four-way, the right choke valve of right control valve is produced valve, standby valve, upper flange, the casing pressure display unit, left side sleeve valve, big four, lower flange, right sleeve valve, stop up and form, lower flange is connected with the gas well sleeve pipe, big four is installed in lower flange, left sleeve valve is installed in the big four both sides, right sleeve valve, right sleeve valve right-hand member is installed and is stopped up, left side sleeve valve left end mounting sleeve pressure-display device, install flange on the big four, standby valve is installed on the upper flange, install on the standby valve and produce valve, produce little four-way is installed on the valve, the tubing pressure display unit is installed on the little four-way, left control valve is installed in little four-way left side, left choke valve is installed in control valve left side, a left side, right control valve is installed on little four-way right side, and right choke valve is installed on right control valve right side.
The beneficial effects of the utility model are: simple in structure, parts are few, and are in light weight, and processing cost is low, are convenient to carrying and installation, time saving and energy saving, reduce expenses, easy to use, and gas well can early drive a well, and has remarkable economic efficiency.
Description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model is by left choke valve 1, left side control valve 2, tubing pressure display unit 3, little four-way 4, right control valve 5, right choke valve 6, produce valve 7, standby valve 8, upper flange 9, casing pressure display unit 10, left side sleeve valve 11, big four 12, lower flange 13, right sleeve valve 14, stopping up 15 forms, lower flange 13 is connected with the gas well sleeve pipe, big four 12 is installed in lower flange 13, left sleeve valve 11 is installed in big four 12 both sides, right sleeve valve 14, right sleeve valve 14 right-hand members are installed and are stopped up 15, after taking off, obstruction 15 can in sleeve pipe, inject liquid, informal letter is in well control, left side sleeve valve 11 left end mounting sleeve pressure-display devices 10, install flange 9 on the big four 12, standby valve 8 is installed on the upper flange 9, install on the standby valve 8 and produce valve 7, produce little four-way 4 is installed on the valve 7, tubing pressure display unit 3 is installed on the little four-way 4, left control valve 2 is installed in little four-way 4 left sides, left choke valve 1 is installed in control valve 2 left sides, a left side, right control valve 5 is installed on little four-way 4 right sides, and right choke valve 6 is installed on right control valve 5 right sides.
During production, choke valve 1, left control valve 2 and right control valve 5, right choke valve 6, a use cover wherein, another set of as standby, repair and replacement need not stop production, after producing the parts damages of valve more than 7, can close standby valve 8, change the parts that damage then, therefore, the utility model is easy to use.
