Abstract
The utility model relates to an oil field oil well pipeline environment-friendly safety sampler which mainly solves the problem in the prior art that the existing oil well sampler is unreasonable in structure, free of oil-gas separating and gas discharging device and unsafe, and splashing is easy to happen. The oil field oil well pipeline environment-friendly safety sampler is characterized in that an annular space is arranged between a three-way sleeve (3) and a sampling pipe (2). A spherical baffle (4) is welded on an outer wall of the three-way sleeve, a sealing cover (5) is sleeved on an outer wall of the three-way sleeve on the lower portion of the spherical baffle, and the sealing cover covers on a bottle opening of a sampling bottle (10). A natural gas outlet (8) is arranged on one side of the three-way sleeve, and a natural gas pipe (9) is connected with the natural gas outlet. An outlet pipe head (6) is connected with the outlet end of the sampling pipe in an inclined mode. A plurality of natural gas escape pipes (7) are arranged on the upper portion of the outlet pipe head. A filter screen (11) is arranged on the upper port of the sampling pipe. The oil field oil well pipeline environment-friendly safety sampler can prevent crude oil from splashing, eliminates potential safety hazards and is environmentally friendly.
Description
Technical field
The utility model relates to a kind of sampler in the oil field development technical field, particularly a kind of oilfield pipeline Environmental Safety sampler.
Background technology
In the oil field oil recovery manufacturing process, need carry out sample examination to the crude oil of extraction.In the sampling process, oil gas impacts the crude oil in the sampling bottle and produces splash, and the natural gas of separating in the crude oil can carry the crude oil ejection sampling bottle that splash rises.Perhaps when oil well is taken a sample, when the sampler flow increases suddenly and has little time to close sample cock, make oil sample overflow sampling bottle and pollute.And existing sampler all is installed in the oil well incubator mostly, the natural gas of separating in the crude oil during sampling can spray from the bottleneck of sampling bottle and accumulate in the incubator, the potential safety hazard of just exist blast when natural gas is accumulated to certain concentration, catch fire, personnel poisoning.Existing oil well sampler structure is unreasonable, does not have Oil-gas Separation and exhaust plant, can produce splash during sampling, and particularly when the big oil well of gas production was taken a sample, the splash phenomenon was particularly serious.Cause the person, wellhead assembly and environment pollution.
Summary of the invention
Technical problem to be solved in the utility model is to overcome that the existing oil well sampler structure that exists in the background technology is unreasonable not to have Oil-gas Separation and the easy splash of exhaust plant and a unsafe problem, and provide a kind of oilfield pipeline Environmental Safety sampler, this oilfield pipeline Environmental Safety sampler, can prevent the crude oil splash, eliminate safe hidden trouble, free from environmental pollution.
The invention for solving the technical problem can reach by following technical solution: this oil pipeline Environmental Safety sampler comprises oil connection, probe tube, sampling bottle, the fixedly connected probe tube in described oil connection bottom, the outer cover of described probe tube is equipped with a threeway sleeve pipe, threeway sleeve pipe end face and union weld together, and the threeway sleeve pipe is parallel with probe tube; Between threeway sleeve pipe and the probe tube annular space is arranged, probe tube is than 5～55 millimeters of threeway sleeve pipe 3 length, outer wall at the threeway sleeve pipe is welded with sphere shape baffle plate, is with a seal cover at the outer wall of the threeway sleeve pipe of sphere shape baffle plate bottom, and seal cover covers on the bottleneck of sampling bottle; Gas outlet in that threeway sleeve pipe one side has is connected with the natural gas conduit on the gas outlet; The port of export of probe tube tilts to connect the outlet tube head; The center line of outlet tube head and the angle of probe tube center line are between 30～60 degree; Described outlet tube head top has some natural gas effusion tracheaes; Described probe tube upper port is equipped with filter screen.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this oil pipeline Environmental Safety sampler is owing to adopt said structure, can prevent from that the crude oil splash goes out sampling bottle in the oil well sampling process to pollute.The natural gas that produces in the sampling process can be drawn sampling bottle, and enter in the blowdown bucket, improve working environment, reduce natural gas to the injury of the person, prevent the generation because of sampling catching fire of causing that gas accumulation produces in incubator, explosion accident.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: 1-oil connection, 2-probe tube, 3-threeway sleeve pipe, 4-sphere shape baffle plate, 5-seal cover, 6-tube head, 7-tracheae, 8-gas outlet, 9-conduit, 10-sampling bottle, 11-filter screen.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, this oilfield pipeline Environmental Safety sampler comprises oil connection 1, probe tube 2, sampling bottle 10, the fixedly connected probe tube 2 in described oil connection 1 bottom, the outer cover of probe tube 2 is equipped with a threeway sleeve pipe 3, threeway sleeve pipe 3 end faces and union 1 weld together, and threeway sleeve pipe 3 is parallel with probe tube 2; Between threeway sleeve pipe 3 and the probe tube 2 annular space is arranged, probe tube 2 is than long 5～55 millimeters of threeway sleeve pipe 3, is welded with sphere shape baffle plate 4 at the outer wall of threeway sleeve pipe 3, is used for stopping the splash of extraction liquid sample, baffle plate 4 is sphere shape, is conducive to the rainy day rainwater and falls in the sampling bottle 10; Outer wall at the threeway sleeve pipe 3 of sphere shape baffle plate 4 bottoms is with a seal cover 5, and seal cover 5 covers on the bottleneck of sampling bottle 10; Gas outlet 8 in that threeway sleeve pipe 3 one sides have is connected with natural gas conduit 9 on the gas outlet 8, natural gas conduit 9 openends are outdoor; The port of export leaning thread of probe tube 2 connects outlet tube head 6; The center line of outlet tube head 6 and the angle of probe tube 2 center lines are between 30～60 degree; Described outlet tube head 6 tops have some natural gas effusion tracheaes 7, are convenient to natural gas and overflow; Described probe tube 2 upper port are equipped with filter screen 11, are used for filtering the impurity in the extraction liquid sample.
When this oil pipeline Environmental Safety sampler used, union top was connected with the sampling control valve, opens the sampling control valve, the extraction liquid that contains natural gas enters from the union centre bore, by probe tube, enter in the probe tube, the natural gas in the extraction liquid is separated.Natural gas is overflowed through the annular space between threeway sleeve pipe and the probe tube, and from the gas outlet outflow of threeway sleeve pipe, the natural gas of outflow is led away by conduit; Crude oil is stayed in the sampling bottle.Natural gas has had a passage, can not cause extraction liquid sample splash phenomenon, guarantees safety.
