Description

The antifreeze gas defence wellhead sampling of hand-held mobile device

One, technical field:

The utility model relates to a kind of antifreeze gas defence wellhead sampling of hand-held mobile device of oil field oil recovery sampling usefulness.

Two, background technology:

In oilfield process, must carry out at regular time and quantity sampling to oil that well mouth of oil well goes out, to obtain every physical and chemical performance index of this oil product.And in common sampling process, can have following common problem: 1, when old-fashioned sampler is outside the well head incubator, can run into the situation that sampling oil is frozen when take a sample winter, cause fuel-displaced not freely or at all can't be fuel-displaced, have a strong impact on sampling work; 2, the sample tap of old-fashioned sampler is near incubator and can not moving, when beginning to take a sample, sample tap outwards exhaust earlier, and contain a large amount of greasy dirts in the gas of discharging, can to the well head incubator and around ground pollute, have a strong impact on environment; 3, when old-fashioned sampler can't be taken a sample outside the well head incubator, just must arrive sampling in the incubator, because the space is narrow and small in the incubator, equipment pipe is numerous, the layout complexity causes operation easier to become big; 4, the most seriously be, in the sampling process, poisonous, harmful gas air accumulation such as the hydrogen sulfide of oil-water well (H2S) in incubator, the serious accident that confined space easily makes the staff poison; When 5, in incubator, taking a sample equally, also can cause oil pollution in the case, and greasy dirt is very difficult to cleaning, causes contaminated environment.

Three, summary of the invention:

The purpose of this utility model be to propose a kind of can be at the antifreeze gas defence wellhead sampling of the hand-held mobile that open environment is taken a sample device

The purpose of this utility model is achieved in that the antifreeze gas defence wellhead sampling of hand-held mobile device, it comprises forward and backward hand-held that spins, hand-held before inserting in interior push rod, the handle that is connected with push rod, brace, hand-held with the back the sealing nut, the pivot pin that spin, with the joint of the active socket in pivot pin rear end, the high-pressure hose that is communicated with joint.Forward and backward hand-held handle is the cavity body of central hole, is fixed with valve seat in both inner screw-on places, and the back is hand-held the rear end sealing nut that spins.Be provided with ball seat between valve seat and sealing nut, be placed with steel ball between ball seat and valve seat.Be connected with pivot pin in sealing nut, pivot pin is held active another sealing nut that is socketed with in addition, and sealing nut and joint spin, and connect high-pressure hose behind the joint.Preceding hand-held the active installing brace of front end, brace end in addition is connected with L shaped handle is active.Hand-held front end is connected with clamping nut preceding, is inserted with push rod in it, preceding hand-held internal cavities is communicated with a spray bar.

The utility model is simple in structure, hand-holdable remote-controlled operation, thus avoid in incubator, taking a sample, handling safety, reliable, also can prevent the situation that oil is frozen in the pipe simultaneously, and the waste oil before will take a sample, waste gas are concentrated and are recycled safety and environmental protection.

Four, description of drawings:

Concrete structure of the present utility model is provided by following drawings and Examples:

Fig. 1 is the antifreeze gas defence wellhead sampling of a hand-held mobile device structural representation;

Fig. 2 is the antifreeze gas defence wellhead sampling of hand-held mobile device structural representation when being connected with well mouth of oil well.

Five, the specific embodiment:

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Embodiment: as shown in Figure 1, 2, the antifreeze gas defence wellhead sampling of hand-held mobile device comprises spin preceding 4, the back is hand-held 7, hand-held before inserting in 4 interior push rods 5, the handle 17 that is connected with push rod 5, brace 2, hand-held with the back 7 sealing nuts that spin 11, pivot pin 12, with the joint 13 of the pivot pin active socket in 12 rear ends, the high-pressure hose 14 that is communicated with joint 13.Preceding 4, back is hand-held to be fixed with valve seat 6 to 7 cavity body that are central hole in both inner screw-on places, and hand the 7 rear ends sealing nut 11 that spins the back.11 of valve seat 6 and sealing nuts are provided with

ball seat

9, and 6 of ball seat 9 and valve seats are placed with steel ball 8.Ball seat 9 is a T shape platform, and its stub end is towards steel ball 8, and the microcephaly holds the outer spring 10 that is with.Be connected with pivot pin 12 in sealing nut 11, pivot pin 12 is the circular shaft of central hole.Pivot pin 12 is held active another sealing nut 11 that is socketed with in addition, and sealing nut 11 and joint 13 spin, and joint 13 central hole connect high-pressure hose 14 behind the joint 13.Preceding hand-held the active installing brace 2 of 4 front ends, brace 2 is end and L shaped 17 active connections of handle in addition.Hand-held 4 front ends are connected with clamping nut 3 preceding, are inserted with push rod 5 in it, push rod 5 front ends stretch out clamping nut 3, pass handle 17, are rotary with nut 1 on the push rod 5 of handle 17 both sides, and handle 17 is connected with push rod 5.Valve seat 6 is stretched in push rod 5 rear ends.Preceding handing is communicated with 4 internal cavities with a spray bar 16, spray bar 16 front ends installing shower nozzle 15.

During use, installing high pressure connection 19 is connected high-pressure hose 14 with high pressure connection 19 on production tree well head high pressure valve 20.Owing in production tree, there are a large amount of toxic gases, so before collection, carry out emptying earlier, toxic gas is collected, focus on.Hand-held subsequently, pinching handle 17, handle 17 goes push rod 5 to interior top to hand-held, and push rod promotes steel ball 8, thereby opens valve seat 6, and oil is pressed to spray bar 16 through high pressure by joint in the production tree, finally by shower nozzle 15 ejections, finishes sampling.After sampling finishes, sampler hung back in the incubator get final product.

Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
