Abstract

The utility model relates to a hot water circulation mixed well head controller used for an oil field extraction well head, solving the problem that the well head is easy to be frozen and plugged in northern cold zone in the winter. The utility model is characterized in that a three-way (19) is sequentially connected with a hot water short joint (16) and a valve body (13); the valve body (13) is internally provided with a valve ball (8) built in a controller (10) and connected with a guide screw (22); the controller (10) is internally provided with a theft protection room (5); the three-way (19) and the short joint (16) are internally provided with oil passages (17, 21), leading external chambers of the passages (17, 21) to be provided with a plurality of hot water circulation pipes (3, 1); the lower part of the valve body (13) is communicated with water pipes (11, 14) by a short joint (12). The utility model has the advantages of extracted crude oil always in suitable temperature, being suitable for production requirement in northern cold areas, no freezing and blocking phenomena in the winter, avoiding the stealing phenomenon, small land occupying, and saving space.

Description

Hot water circuit is mixed the hot type well head controller

Technical field:

The utility model relates to the used device of oil well mouth, belongs to hot water circuit and mixes the hot type well head controller.

Background technology:

The oilfield exploitation great majority adopt oil pumper to recover the oil at present.For the ease of control well head oil production, the well head place that is everlasting adds well head controller.And controller mostly is 250 model well head controller, decentralized wellhead controller and simple wellhead controller greatly at present, these controllers have a common drawback, be exactly that controller itself does not have the thermal field, be not suitable for the production needs of the northern cold zone in areas such as grand celebration, occur freezing stifled phenomenon in the winter time easily, workman's workload is big after causing the winter, simultaneously do not have anti-theft feature yet, make the lawless person to steal at any time and drain the oil that wellhead equipment is messy in addition, floor space is big, and influence is produced.

Summary of the invention:

The purpose of this utility model is to avoid the deficiency of above-mentioned technology existence and provides a kind of suitable cold zone use and antitheft hot water circuit to mix the hot type well head controller.

Adoptable technical scheme is: this hot water circuit is mixed the hot type well head controller, comprises well head threeway and threeway screw thread up and down, the valve body that the threeway transverse end connects the hot water short circuit and links to each other with controller by nut successively; The continuous valve ball of leading screw that is built in the controller is arranged in the valve body, in controller, be provided with antitheft chamber; Have oil flow channel to make channel outer wall and threeway and short circuit inwall form ring cavity in threeway and the short circuit and be used for built-in some hot-water circulation pipes, there are the some hot-water circulation pipes in oil stream standpipe and the standpipe exocoel threeway termination; Valve body lower portion is communicated with water pipe by pipe nipple.

Above-mentioned circulation pipe is 5.

The beneficial effect of this controller is: because this controller is provided with oil flow channel and hot-water circulation pipe at the horizontal upright end place of well head threeway, make the crude oil of extraction be in all the time among the preference temperature environment, be fit to northern cold zone production needs, can not occur freezing stifled phenomenon in the winter time; Have antitheft chamber to have anti-theft feature in addition, stop the generation of steal phenomenon, wellhead equipment concentrates on threeway place, and floor space is little, saves the space.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is vertical views of accompanying drawing 1;

Accompanying drawing 3 is A-A sectional views of accompanying drawing 1.

The 1-hot-water circulation pipe, the last screw thread of 2-, 3-hot-water circulation pipe, 4-sealing mat, the antitheft chamber of 5-, 6-subring, 7-sealing mat, 8-valve ball, the 9-plug, 10-controller, 11-water mixing pipe, 12-pipe nipple, the 13-valve body, 14-comes water pipe, the 15-nut, the 16-short circuit, 17-oil flow channel, 18-nut, the 19-threeway, screw thread under the 20-, 21-standpipe.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

As Fig. 1 in conjunction with Fig. 2, shown in 3, this hot water circuit is mixed the hot type well head controller, comprise well head threeway 19 and threeway screw thread (2 up and down, 20), threeway 19 transverse end are successively by nut (18,15) connecting hot water short circuit 16 reaches and valve body 13, valve body 13 links to each other with controller 10, nut 18 places are added with sealing mat 4 and seal, and prevent that profit from leaking, and in addition subring 6 and sealing mat 7 make nut 15 more tight with short circuit 13 sealings at nut 15 places, prevent that profit from leaking, valve ball 8 is arranged in the valve body 13, and this valve ball 8 links to each other with the leading screw 22 that is built in 10 li of controllers, in order to open and close valve body 13 under the control of controller 10; In controller 10, be provided with antitheft chamber 5, avoid the well head facility stolen; There is oil flow channel 17 to make passage 17 outer walls and threeway 19 and short circuit 16 inwalls form ring cavity in threeway 19 and the short circuit 16 and is used for built-in 5 hot-water circulation pipes 3, there are 5 hot-water circulation pipes 1 in oil stream standpipe 21 and standpipe 21 exocoels threeway 19 terminations, make the crude oil of extraction be in all the time among the preference temperature environment, be fit to northern cold zone production needs, can not occur freezing stifled phenomenon in the winter time; Valve body 13 bottoms are communicated with water pipe (11,14) by pipe nipple 12, make extraction oil mix with process water pipe (11,14) and enter next flow process after into hot water mixes mutually.Easy, practical, be fit to be extensive use of.
