This is novel has following characteristics: first, this kill manifold forms double-vane structure by the first hand sluice valve, the second hand sluice valve, the 3rd hand sluice valve, the 4th hand sluice valve, the structure design of double-vane can be carried out kill job at both wings simultaneously, so the two-way function power of both sides kill job can be cancelled out each other, and this kind of relatively traditional kill manifold of structure has advantages of compact conformation, balance and stability performance is high, operating efficiency is high.Kill manifold operating efficiency after improvement can improve 100%, and this kind of structure improved operating efficiency widely, reduced operating cost.Second, this novel kill manifold is provided with pressure meter on reducing five-way, pressure meter can be used for observation well downforce situation of change at any time, field operation personnel can detect in real time down-hole pressure by pressure gauge reading at any time and change, once pressure jump can be taked pressure-relief measure in time, ensure the safety of operation.The 3rd; this novel kill manifold open flow process adopts the structure of the 3rd hand sluice valve and the 4th hand sluice valve control; compare traditional single gate valve type structure; the structure safety in utilization of double gate valve control is higher; even a gate valve has broken down in the process of open flow operation; also have another gate valve can control keying, can well protect operating personnel's life security in the time there is emergency case, the structure of double gate valve is also more convenient in the time of maintenance in addition.
As the utility model embodiment, in order to keep the stable of valve sets, the supporting seat 14 that supports described valve sets adopts 4, certainly, also can adopt 3, and 5 are waited supporting seat.
The first hand sluice valve 2 that this novel kill manifold device adopts, described the second hand sluice valve 3, the 3rd hand sluice valve 4, the 4th hand sluice valve 5 are by component compositions such as valve body, flashboard, valve seat, valve gap, valve rod, balancing poles, between flashboard and valve rod, balancing pole, be connected respectively by T-shaped groove structure, switching performance is safe and reliable.At valve inner, valve seat is installed, between valve seat and flashboard, realizes keying by slippage, flashboard and sealing surface of seat adopt carbide alloy, and sealing performance is safe and reliable; In valve body upper end, valve gap is installed.The effect of valve gap is that protection valve body internal construction is exempted from exogenous impurity interference.
If the use of fluid,matching cylinder pressure can realize hydraulic remote process control, surge and control the labour intensity that has reduced field operation workman, improve operating efficiency, ensure operational security.Flap type is rising stem type structure, two strong thrust ball bearings of load-bearing capacity is housed in valve and bears the load of valve opening and closing, thereby have advantages of that switch moment is little, and valve can be realized the operation light and flexible in high-voltage load situation.Flap type flashboard and valve seat adopt metal sealing, surface spraying weld Ni60 alloy, and compared with conventional alloys material, it is high that Ni60 alloy sealing surface has intensity, and abrasion resistance is good, and the feature that corrosion resistance is high effectively raises application life of valve.In valve body, all encapsulants all adopt international advanced material HNBR (the high saturated hydrogenation fourth of domestic general designation is fine), have ensured the overall sealing performance of kill manifold device.
The first ball-and-seat 6, the second ball-and-seat 7 that this novel kill manifold device adopts form by component such as valve body, valve gap, spool, valve seat, springs; Valve seat and spool are installed in valve body, and sealing realizes by valve seat, spool, and in pressurized situation, pressure forces spool to move up, and Compress Spring distortion, forms path, and after pressure disappears, spring force forces spool return, realizes liquid one-way flowing.In valve body upper end, valve gap is installed, the effect of valve gap is that protection valve body internal construction is exempted from exogenous impurity interference.This kind of ball-and-seat adopts FC type valve body structure spool, compared with traditional dish-type spool, has better sealing performance.Spool and valve seat adopt cylindrical spring pushing, make sealing surface produce certain pretightning force to ensure low pressure seal, and high pressure sealing produces this higher pressure by the pressure of medium on sealing surface, and realizes self sealss effect.
Traditional bolted material of kill manifold device is general, and that force employing is 42CrMo, this material mechanical performance under cryogenic conditions reduces greatly, often fracture affects the overall sealing performance of kill manifold, so just improved the cost of maintenance, the utility model is reform in the selection of bolt connection material, adopt 06Cr15Ni25Ti2MoAlVB austenitic stainless steel material, after solution treatment, to have intensity high for this bolt material, anti-low temperature environment shows good feature, can under low temperature exposed environments, use, greatly improve the safety factor of kill manifold device.
The surrounding of the reducing five-way 1 of this kill manifold is symmetrical the first hand sluice valve 2, the second hand sluice valve 3 and the 3rd hand sluice valve 4, the 4th hand sluice valve 5 of being distributed with respectively.Be connected to respectively the first ball-and-seat 6, the second ball-and-seat 7 at the end of the first hand sluice valve 2, the second hand sluice valve 3; The second thread flange 11 is connected with relief line, and the 3rd thread flange 12 is connected with drilling spool by connecting line.In the time of open flow operation, close the first hand sluice valve 2, the second hand sluice valve 3, open the 3rd hand sluice valve 4, the 4th hand sluice valve 5, implement open flow operation.In the time of kill job, close the 3rd hand sluice valve 4, open the first hand sluice valve 2, the second hand sluice valve 3, open the 4th hand sluice valve 5, unload the plug 10 that the first thread flange 9 connects above, ball-and-seat is connected with kill pump, pump into well killing fluid to down-hole.The ball-and-seat of left and right both wings can be distinguished and is connected with two kill pumps simultaneously, while operation.Pressure meter 8 is connected with reducing five-way 1 by adpting flange, in real time monitoring task pressure.
In this manual, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is and the difference of other embodiment, between each embodiment identical similar part mutually referring to.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model by can not be restricted to herein these embodiment not, but to meet the widest scope consistent with principle disclosed herein and features of novelty.
