Easy device, is mainly used in that pressure is higher, associated gas is more, interval is fuel-displaced, the oil well sampling containing hydrogen sulfide.
Background technology
Found by multiple field sampling, traditional Samper for oil well often has some defects in sampling process.
Such as,（1）Higher or when managing defeated well sampling containing a large amount of associated gases, oil well pressure, because petroleum pipeline pressure is larger,
Easily there are expulsion events in routine sampling device, is taken when serious because splash and line pressure cause greatly operating personnel not approach
Sampling device simultaneously closes sampling valve in time, crude oil leakage occurs, pollutes environment；（2）For the fuel-displaced oil well sampling of interval, due to oil well
The upper liquid time is uncertain to cause sampling personnel needs in well head waiting sampling, short then half an hour length then a few hours, has a strong impact on
Sampling efficiency, such case is particularly common in the relatively low oil field of yield；（3）When needing to the production fluid and associated gas of oil well simultaneously
During sampling, routine sampling device can not realize Oil-gas Separation, the collection to associated gas.（4）Taken for the oil well containing hydrogen sulfide
During sample, easily occur hydrogen sulfide poisoning phenomenon when being sampled operation using routine sampling device, seriously endanger sampling personnel's body
Body health.（5）Because routine sampling valve is on sampling by-pass line, by-pass line and sampling valve front end always retain one section of deposition
Sample.During per sub-sampling, it need to first bleed off deposition sample to ensure the accuracy of sampling.During winter, by-pass line temperature is relatively low, for viscosity
, easily there is wax deposition in larger crude oil, causes to deposit sample and is difficult to release or showing of sample that difficulty occurs that blocking occurs in sampling line
As.
