Analysis.Normally produce and steal crude oil position at wellhead sampling, pressure gauge etc. be most.Stolen position is mainly sampling
Place.Therefore the improvement of sampler becomes the theme of technical precaution.
Well mouth of oil well sampler used at present by be welded in well mouth of oil well stand conduit on weld screw thread section header, valve and
Sample elbow composition.The shortcomings that such sampler is：There are problems in use：Repeatedly valve opening door takes
Sample.Operation element amount is big；There are dead oil in device, emptying is polluted when sampling；When drawing oil sample, solution gas abjection, crude oil splashes
Out.Accuracy that is not only unclean but also influencing sample；It since sample cock is used for multiple times, causes to fit badly, crude oil water clock；It takes
Oil sample out is fluid outer section at tube wall, and oil sample does not have representativeness；It is low wellhead temperature is not suitable for.Winter can not take sample
Well.It is not suitable for the big well of interval producing well, gas yet；Gate is opened continuously to drain the oil, it is non-anti-theft；Gate and sampling elbow easily quilt
It steals, stolen occurs or failure is unable to control；Non-anti-theft oil, etc. at wellhead back-pressure gate.
