The beneficial effects of the utility model are: gas, liquid can be carried out being separated and collecting on ground; In sampling process, wait for for a long time near sample tap without the need to staff, staff's long-time gas sucking resident fluid discharge in sampling process can either be avoided, and then protect the personal safety of sampling personnel, turn improve work efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram being applied to the well head sampling apparatus of prospect pit formation testing of the utility model;
Embodiment
Below in conjunction with accompanying drawing, utility model is described in further detail, can implements according to this with reference to instructions word to make those skilled in the art.
As shown in Figure 1, a kind of well head sampling apparatus 1 being applied to prospect pit formation testing, comprising: support 110, and it is for fixing and support well head sampling apparatus 1; Sampler 120, it is for the detected sample with splendid attire collection and make its gas-liquid separation, the inlet 121 entered for sample is provided with on the top of described sampler 120, liquid feed valve 122 is provided with at inlet place, the air hatch 123 for gaseous sample effusion after gas-liquid separation is provided with at sampler 120 top, be provided with at air hatch place and get air valve 124, be provided with the liquid taking port 128 of discharging for fluid sample after gas-liquid separation in the bottom of sampler, be provided with liquid taking valve 129 at liquid taking port place.
Using method, first before test drives a well, is positioned over the utility model near data head, is coupled together, be connected the pipeline of appropriate length at liquid taking port 128 respectively with air hatch 123 by the inlet 121 of pipeline by the cock on data head and sampler 120.When needing sampling, open the liquid feed valve 122 of data head cock and inlet 121 so that sample enters in sampler 120, when sample enters before sampler, at least liquid taking valve 129 and to get in air valve 124 one and be in open mode should be kept, ensure that separation vessel can not bear too large pressure.When getting fluid sample, first opening and getting air valve 124, then open inlet 128, allow sample enter in sampler 120, after waiting for a period of time, fluid is piled up in the bottom of sampler due to gravity segregation, and the gas in sample is discharged by air hatch 123, open again and get valve 129 and carry out getting fluid sample.When getting gaseous sample, first liquid taking valve 129 is opened, then liquid feed valve 122 is opened, by the emptying rate of liquid that emptying rate of liquid original in sampler maybe may exist, then open and get air valve 124, close liquid taking port 129 and carry out getting gas sample.After sampling terminates, pipeline of being correlated with is removed, and is removed by this well head sampling apparatus.
In another embodiment, the bottom of described sampler 120 is circular arc, is convenient to fluid sample and is gathered in liquid taking port 128 place.
