Abstract
The utility model relates to a tubing hanger device with a cut-off valve, including a tubing hanger device and a tubing four-way, the two of which are connected. The utility model is characterized in that: between the tubing four-way and the tubing hanger device is arranged with a valve-core and valve-seat mechanism, one side of which is connected to the fluid cylinder through the gear-rack mechanism; the pipeline exit of the external connection pressure source is connected to the fluid cylinder; the valve-core and valve-seat mechanism is a fixed ball valve, sliding ball valve or plug valve; the valve-core material is anticorrosive material. The advantages of the utility model are that: the rapid entering into the shut-in reparing state can be realized during the production state; the well killing equipment and material are not necessary;the operation expense is saved; no pollution is caused to the oil gas well formation;the output after the replacement or the repairment of Christmas trees is not affected.
Description
Technical field
The utility model relates to a kind of tubing hanger device with stop valve, can be used for a kind of production tree device in oil field, can conveniently cut off main latus rectum oil, atmospheric pressure, so that remove production tree equipment place under repair and transformation, belongs to tubing hanger device technique field.
Background technology
Production tree moves under oil field high pressure and corrosive environment for a long time because of it, and imitating corrosion can appear and dash loss in equipment.The operation means of changing these equipment are to carry out kill job, stop production but kill job need stop well, employ expensive kill-job equipment, expend enormous expenditure and a large amount of operation duration, kill-job also can cause hydrocarbon contamination, reduces the recovery ratio of oil gas well, directly influences productivity effect.
Summary of the invention
The purpose of this utility model provides and a kind ofly can enter closing well fast in production status and repair state, does not employ the tubing hanger device of the band stop valve of large-scale kill-job equipment and material.
For realizing above purpose, the technical solution of the utility model provides a kind of tubing hanger device with stop valve, comprise tubing hanger device and oil pipe four-way, the tubing hanger device links to each other with the oil pipe four-way, it is characterized in that, be provided with spool valve seat mechanism between oil pipe four-way and tubing hanger device, spool valve seat mechanism one side is connected with fluid cylinder by pinion and rack, and the pipeline outlet that outreaches pressure source is connected with fluid cylinder.
Described spool valve seat mechanism is Fixed ball valve, float ball valve or plug valve, and valve core material is an anti-corrosion material.
The utility model is provided with spool valve seat mechanism between oil pipe four-way and tubing hanger device, can under existing working condition, carry out closing well easily, and in a short time with ready new production tree equipment replacement to well head, carry out getting final product opening well and making production behind the test pressure, the oil gas well is not polluted.
The utility model is installed in whole valves, driving cylinder and pinion and rack the inside configuration of former tubing hanger, promptly do not change the inside and outside structure and the size of tubing hanger, and the hermetically-sealed construction that still keeps former tubing hanger can be installed in various oil pipe four-ways and use easily.
The utility model has the advantages that can enter closing well fast in production status repairs state, do not employ large-scale kill-job equipment and material, save the operation spending, pollution-free to oil gas well stratum, the not influence of output to replacing or after repairing production tree.
Description of drawings
Fig. 1 is the tubing hanger apparatus structure schematic diagram of band stop valve.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the tubing hanger apparatus structure schematic diagram of band stop valve, the tubing hanger device of described band stop valve is made up of tubing hanger device 1, spool valve seat mechanism 2, pinion and rack 3, fluid cylinder 4, pipeline outlet 5 and oil pipe four-way 6.
Tubing hanger device 1 links to each other with oil pipe four-way 6, spool valve seat mechanism 2 is installed between tubing hanger device 1 and oil pipe four-way 6, described spool valve seat mechanism 2 is Fixed ball valve, float ball valve or plug valve, valve core material is an anti-corrosion material, oil pipe four-way 6 one ends are connected with fluid cylinder 4 by pinion and rack 3, and the pipeline that outreaches pressure source exports 5 and is connected with fluid cylinder 4, and pinion and rack 3 is by fluid cylinder 4 drivings, the pipeline outlet 5 outer pressure sources that connect are with the action of control fluid cylinder.
Open spool valve seat mechanism 2, make production tree equipment be in the ordinary production operating mode, close spool valve seat mechanism 2, promptly detachable equipment carries out maintenance work.By discharging on the production tree the production valve and observe manometer on the tree, monitor whether the oil gas well is closed or open-minded.
The power that can be used as the switch spool that the oil gas well pressure is high, otherwise then use handlance to carry out switching manipulation.
Claims (2)
1. tubing hanger device with stop valve, comprise tubing hanger device (1) and oil pipe four-way (6), tubing hanger device (1) links to each other with oil pipe four-way (6), it is characterized in that, between tubing hanger device (1) and oil pipe four-way (6), be provided with spool valve seat mechanism (2), oil pipe four-way (6) one ends are connected with fluid cylinder (4) by pinion and rack (3), and the pipeline outlet (5) that outreaches pressure source is connected with fluid cylinder (4).
