Abstract
The utility model discloses a double-pipe watering antifreeze well head combined device which comprises an oil pipeline on which a valve body is mounted, wherein on end of the valve body is connected with an oil pipe connecting pipe and the other end thereof is connected with a water feed pipe, a feed valve is arranged on the water feed pipe, an oil return valve and a drain valve are arranged in front of the valve body, a well flushing valve is arranged at the back of the valve body; a watering regulation valve, an oil-water communication pipe, a check valve and a constant pressure air bleeder are arranged on the upper part of the valve body, an oil return pipe and a connecting pipe are arranged on the lower part of the valve body, and the connecting pipe is connected with a sleeve. The utility model has the advantages that: the double-pipe watering antifreeze well head combined device has reasonable design, simple structure, convenient use and mounting, adopts the watering to realize dilution and viscosity break and heating rise viscosity break, improves the temperature of the watering to the most extent for improving the watering viscosity break effect, improves the oil mining productivity and yield of thick wells, and ensures the normal production of oil wells.
Description
Technical field
The utility model belongs to the valve gear of well head, particularly relates to the antifreeze well head composite set of a kind of two-tube water mixing.
Background technology
Viscous crude has big, mobile poor, the big characteristics of exploitation difficulty of denseness.Flow velocity is low behind crude oil extraction ground, and temperature descends fast, and viscosity can increase, and this just causes oil flow resistance big, and wellhead back pressure is big, a series of problems such as difficulty of transportation.After particularly entering winter, the temperature fall is big, and the increase of extraction oil viscosity is very big, carries difficulty more.When oil well produced crude oil difficulty of transportation occurs on ground, cause the disconnected bar of the heavy oil wells well of lying, pit shaft, pipeline stop up and cause oil well production unusual, and manufacturing parameter situation such as is put forward on can't be rationally and often taken place, and has seriously restricted the ordinary production of heavy oil wells.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of two-tube water mixing antifreeze well head composite set.
The antifreeze well head composite set of two-tube water mixing of the present utility model, be that the valve body formation has been installed on oil pipeline, one end of valve body has connected the oil pipe tube connector, the other end connects water service pipe, on water service pipe, be provided with water-supply valve, be provided with oil return valve in the valve body front and blowoff valve, back are provided with flushing valve, be provided with water mixing control valve, profit communicating pipe, ball-and-seat and valve discharging gas under certain pressure on the top of valve body, be provided with oil return pipe and tube connector, tube connector splicing sleeve in the bottom of valve body.
As further improvement of the utility model, on the oil pipe tube connector, be provided with sample valve and pressure measuring valve.
As further improvement of the utility model, described oil return valve, blowoff valve, flushing valve, water mixing control valve, ball-and-seat and valve discharging gas under certain pressure all have conduit to be connected in valve body, and this conduit was connected with oil return pipe, tube connector and profit communicating pipe.
The antifreeze well head composite set of two-tube water mixing of the present utility model, reasonable in design, simple in structure, easy to install, with water mixing dilution viscosity reduction and water mixing intensification viscosity reduction, at utmost improve the water mixing temperature to improve the water mixing viscosity reducing effect, improve the heavy oil wells tar productivity, improve heavy oil wells output, guarantee the ordinary production of oil well.
