The specific embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further elaborated.
embodiment 1
A kind of extraction element of the water sample for tracer technique between oil well, as shown in Figure 1, this device comprises probe tube 3 and sampling bottle 11, also comprise gun barrel 6, peristaltic pump 5 and PLC control device 9, wherein an end of probe tube 3 inserts in oil pipe 1, and the other end is connected with the bottom of gun barrel 6, in the bottom of gun barrel 6, has also drawn a drain pipe 8, the other end of drain pipe 8 has a plurality of outlets, and this outlet is connected with the openend of corresponding sampling bottle 11 respectively.
Oil, water natural subsidence in gun barrel 6.Sampling bottle 11 is positioned at the below of gun barrel 6, collects the water in gun barrel 6.The hot device 7 of companion is installed in the left and right sides of gun barrel 6.
Be provided with an electrical ball valve in each exit of drain pipe 8.Described PLC control device 9 is controlled sample introduction electrical ball valve, the switch of sampling electrical ball valve and rotation direction, flow and the flow velocity of peristaltic pump.Top at gun barrel 6 and sampling bottle 11 is provided with bleed off pipe, and the liquid in bleed off pipe flows in waste liquid tank.
The concrete operation method that utilizes this device to carry out the water sample sampling is:
