The specific embodiment
With the description of the utility model specific embodiment, can more be well understood to details of the present utility model by reference to the accompanying drawings.But the specific embodiment of the present utility model described here,, for explaining the purpose of this utility model, is only to restriction of the present utility model and can not be understood as by any way.Under instruction of the present utility model, technician can conceive based on possible distortion arbitrarily of the present utility model, and these all should be regarded as belonging to scope of the present utility model.
Please refer to the structural representation that Fig. 1 is the online sampler of the utility model chemical flooding, as shown in Figure 1, the online sampler 200 the utility model proposes is arranged on process pipelines 100, sampler 200 comprises liquid flowing valve 220, pressure relief valve 230, sample cock 240 and fluid valve 250, as shown in Figure 1, on the sidewall of process pipelines 200, along liquid flow direction, be sequentially set with the first connected entrance 101 and the second connected entrance 102, the entrance of the first connected entrance 101 and liquid flowing valve 220 is connected by pipeline 210, the entrance of the outlet of liquid flowing valve 220 and fluid valve 250 is connected by pipeline 210, the outlet of fluid valve 250 is connected by pipeline 210 with the second connected entrance 102, pressure relief valve 230 and sample cock 240 are arranged on the pipeline 210 between liquid flowing valve 220 and fluid valve 230 along liquid flow direction order.
In normal productive process, liquid flowing valve 220 and fluid valve 250 are opening, pressure relief valve 230 and sample cock 240 are all in closed condition, being full of polymer solution and being circulation status in process pipelines 100 and pipeline 210, due to the state of the polymer solution in process pipelines 100 and pipeline 210 in circulation, therefore the polymer solution in pipeline 210 is basic identical with the polymer solution in process pipelines 100, making via the obtained sample of sample cock 240 being arranged on pipeline 210 is the polymer solution of whole tube section nature fluidised form, and be not the solution at tube wall place, and then greatly reduced the error of sampling.When carrying out sampling operation, first close liquid flowing valve 220, close again fluid valve 250, then open pressure relief valve 230, lay down after the pressure in the pipeline 210 between liquid flowing valve 220 and fluid valve 250, open sample cock 240 and access polymer solution, can obtain the polymer solution of whole tube section nature fluidised form, and be not the solution at tube wall place.After sampling, orderly close-down sample cock 240, pressure relief valve 230, then open liquid flowing valve 220 and remove fluid valve 250, return to normal production.Can by aforesaid operations process, the relative simple and fast of operation of the sampler 200 the utility model proposes, through test, the time of sampler 200 single sampling operations of the present utility model shortens more than 20 minutes compared with routine sampling device, has greatly reduced the required time of sampling operation.And the joint of the sampler 200 the utility model proposes is less, also further reduced the security risk under high pressure operating mode.
Through test, compare with traditional sampler, as shown in the table, the sampler 200 average sample viscosity that the utility model proposes improve 83.9 milli Pascals. and second (mpa.s), improve nearly 1 times, its viscosity of taking out sample has been tending towards truly, greatly having reduced sampling error.
