Such sampling mode has several lower several shortcomings:
1, need to first discharge dead oil, easily pollute and waste.
2, when getting chlorine root sample, moisture low well need to take out a large amount of oil samples and precipitate and isolate wherein moisture, and remaining oil sample is only poured in pollution discharge pond.
3, in when sampling, have a large amount of toxic and harmfuls and can be emitted on resample area in company with liquid simultaneously, can cause certain injury to operative employee, and easily cause splash during sampling, pollute site environment.Later stage also needs to clear up greasy dirt, has increased employee's labour intensity, brings so great inconvenience and potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of well mouth of oil well multifunctional airtight sampler.
A kind of well mouth of oil well multifunctional airtight sampler, one side top of containing liquid chamber connects oil-in, the middle part of containing liquid chamber connects the sampling of chlorine root and controls outlet, the middle part inner chamber of containing liquid chamber connects exhaust and controls baffle plate, exhaust is controlled baffle plate and is connected gas-oil separation baffle, exhaust is controlled on baffle plate exhaust screen throttle orifice, gas-oil separation baffle and exhaust are controlled baffle plate and are formed exhaust storehouse, the top, exhaust storehouse of the opposite side of containing liquid chamber connects exhaust opening, the bottom of containing liquid chamber connects sample tap, sample tap connects airtight communicating pipe of sampling and UNICOM's pipe fitting and control ball valve, sampling airtight communicating pipe and UNICOM's pipe fitting is connected the sampling of chlorine root and controls the other end exporting and form the first pipeline with the other end of controlling ball valve, the first pipeline connects one end of back pressure valve, the other end of back pressure valve connects the other end of oil-in and chews sub-set.
The utility model has the advantages that while making to sample can be without first discharging the liquid measure of controlling accurately sampling under dead oil condition, and avoids pollution, waste and personal injury.Can easily contain the conversion between water sample or chlorine root sample according to sampling requirement, also avoided environment pollution and the potential safety hazard in sampling process, brought simultaneously.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of well mouth of oil well multifunctional airtight sampler, one side top of containing liquid chamber 9 connects oil-in 1, the middle part of containing liquid chamber 9 connects the sampling of chlorine root and controls outlet 7, the middle part inner chamber of containing liquid chamber 9 connects exhaust and controls baffle plate 5, exhaust is controlled baffle plate 5 and is connected gas-oil separation baffle 8, exhaust is controlled on baffle plate 5 exhaust screen throttle orifice 4, gas-oil separation baffle 8 is controlled baffle plate 5 with exhaust and is formed exhaust storehouse 3, 3 tops, exhaust storehouse of the opposite side of containing liquid chamber 9 connect exhaust opening 2, the bottom of containing liquid chamber 9 connects sample tap 6, sample tap 6 connects airtight communicating pipe of sampling and UNICOM's pipe fitting and control ball valve 10, sampling airtight communicating pipe and UNICOM's pipe fitting is connected the sampling of chlorine root and controls and export 7 the other end and form the first pipeline with the other end of controlling ball valve 10, the first pipeline connects back pressure valve 12 one end, the other end of back pressure valve 12 connects the other end of oil-in 1 and chews sub-set 11, in figure, the direction of arrow is oily flow path direction.
Sampling control flow: oil is generation Oil-gas Separation from oil-in 1 enters containing liquid chamber 9, oil shock gas-oil separation baffle 8; Gas is discharged from exhaust screen throttle orifice 4; The sampling of chlorine root is controlled outlet 7 and is communicated with back pressure valve 12 rear end pipeline; Containing switching flow between water sample and chlorine root sample; Excess oil discharges airtight communicating pipe.
Embodiment 2: as shown in Figure 1, a kind of well mouth of oil well multifunctional airtight sampler, by oil-in 1, sample tap 6, exhaust opening 2, the sampling of chlorine root, control outlet 7, containing liquid chamber 9, exhaust storehouse 3, exhaust control baffle plate 5, gas-oil separation baffle 8 and excess oil discharge and form communicating pipe, sample in addition airtight communicating pipe and UNICOM's pipe fitting and control ball valve 10, chew sub-set 11, back pressure valve 12; Sampler fuel feed hole is fixed on the gate valve outside of the former sampling of well head; After sampling outlet and chlorine root sampling control outlet series winding, be connected to after cover venting control gate valve; Exhaust opening connect a flexible pipe pick out beyond resample area safe distance in pollution discharge pond.
A multifunctional airtight sampler, when oil well is normally produced, the inlet ball valve of sampler is normally open; The airtight connection ball valve of sampler is normally open; At this moment guaranteed can not have dead oil in whole sampler.Exhaust opening ball valve is closed condition; Vent ball valve closed condition is controlled in the sampling of chlorine root; Sampling outlet gate valve is closed condition.During sampling, first close the airtight connection ball valve of sampler, the pressure fast-descending while opening exhaust opening ball valve in exhaust storehouse and in containing liquid chamber.When pressure drop is during lower than pressure in oil pipeline, the liquid in pipeline will flow to containing liquid chamber, can strike the separation degree that gas-oil separation baffle has strengthened oil gas.Gas can be from exhaust screen exhaust throttle eyelet, through exhaust storehouse, from steam vent, drain into pollution discharge pond.
The sound of giving vent to anger when liquid reaches exhaust control baffle plate in containing liquid chamber has obvious change, with this, judges that the liquid in containing liquid chamber is full.At this moment close the ball valve of exhaust opening, close inlet ball valve, open car oil port ball valve, utilize the overbottom pressure in sampler to access oil sample.Because the volume of containing liquid chamber is certain, so can guarantee to sample the accuracy of liquid measure, during sampling, toxic and harmful can be expelled to blow-down pit from exhaust opening, thereby avoid the injury of toxic and harmful to operating personnel, pollution and waste while reducing sampling, reduce employee's manipulation strength, guaranteed operating personnel's safety.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
