Description
Technical field
Oil exploration technology field is the utility model is related to, specifically a kind of floated degasser of oil exploration.
Background technology
Oil, natural gas have the properties such as volatilization, flammable, heat conduction, absorption, dissolving.Casing-head gas is mainly formed as methane
（C1）, heavy hydrocarbon (C2、C3...) and a small amount of H2、CO2、N2、CO、H2The gases such as S.General casing-head gas heavy hydrocarbon relative amount is 10%~
35%, reservoir gas heavy hydrocarbon relative amount is 0~2%, and condensate gas heavy hydrocarbon relative amount is 10%~13%.Gas detection is compound logging
Important component in construction service, gas detection be by the analysis to drilling fluid petrochina, natural Gas content and component,
Directly to find and evaluate a kind of geochemical well logging method of oil-gas Layer.Main hardware equipment includes：Total hydrocarbon detector, hydro carbons
Component detector, non-hydrocarbon component detector（Or carbon dioxide detector）, H2S detector, degasser, hydrogen generator and
Air compressor etc..Wherein, degasser is the basis of above-mentioned all gas detection, and its effect will exactly be free on drilling fluid
In gas through sirring and separating and loss comes out.
Conventional degasser mainly has following several types：
（1）Float-type continuous drilling fluid degasser
Float-type continuous drilling fluid degasser abbreviation float-type degasser, is gone out by drilling fluid broken blade, collection chamber, sample gas
The composition such as mouth, is a kind of degasser simple in construction, cheap.It is bored using the dynamic caused power breaking of drilling fluid gravity flow
Well liquid, gas therein is set to escape automatically.Because it can only crush drilling fluid top layer, therefore degassing efficiency is low, and only 5% or so.Utilize this
Class degasser can only gather the free gas in drilling fluid.Such degasser is eliminated substantially at present.
（2）Quantitative degasser
Quantitative degasser is a kind of a kind of engine degasser by carrying out thorough degasser to a certain amount of drilling fluid, but
Belong to discontinuous.
（3）Thermal vacuum distills degasser
Thermal vacuum distillation degasser is commonly called as complete de-, is a kind of to carry out backlash sampling degassing using heating, vacuum distillation mode
Device, degasser efficiency high is general up to more than 95%, but belongs to discontinuous.
（4）Electrodynamic type continuous degassing device
Electrodynamic type continuous drilling fluid degasser abbreviation electrodynamic type degasser, it crushes drilling fluid using electric stirring, makes it
In gas effusion.This kind of degasser degassing efficiency typically 20% or so, but deep influenceed by drilling liquid height change and
The continuous degassing in just sincere justice can not be realized.
Above-mentioned four kinds of degassers are protruded and common lacked as the use in oil-gas exploration for many years gradually exposes it
Point, i.e., it can not realize the purpose of real-time continuous degassing free of discontinuities.
For a long time, field of gas detection of the electrodynamic type continuous degassing device in oil-gas exploration is widely used, and is gas
The visual plant and means of detection.The basic functional principle of electrodynamic type continuous degassing device is exactly that motor drives stirring rod to revolve at a high speed
Turn, stir drilling fluid to be crushed in degassing interior, gas escape is come out supplied gas detection and use.But for many years
Application attestation, degasser itself is deep to be influenceed by drilling liquid change, frequently causes liquid level to come to nothing, liquid level just connects after coming to nothing
Air has been touched, has interrupted continuous degassing.Now, it is to apply suction pipe mode to have a kind of degasser in the world, will a kind of tube
Drilling fluid depths is inserted, collects drilling fluid by the principle of absorption, but this mode has also adsorbed in drilling fluid simultaneously
Grain thing and easily cause suction pipe block, it is necessary to propose drilling well liquid level carry out particulate matter exclusion, so at this moment also having resulted in gas
Body collection is interrupted, therefore the continuous degassing being also not carried out on essential meaning.Sum up, there is following for above-mentioned all kinds of degasser
The subject matter of several aspects：
（1）Degassing efficiency is low, can not meet oil-gas exploration needs；
（2）Artificial adjustment degasser height, workload is big, dangerous big；
（3）Adjusted again it was found that coming to nothing, had resulted in gas halts, reduce work quality；
（4）Liquid level height changes frequently, and manually operated degasser height is unable to reach promptness at all；
（5）It is difficult that the stirring theory of stirring rod can not exclude stirring caused by high density and high viscosity drilling fluid；
（6）The erection installation of degasser is complicated, and space-consuming is big, influences other operations, and is unfavorable for occupational health protection；
（7）The automatically and successively property of degassing can not be realized, influences oil-gas exploration benefit.
In oil-gas exploration, also without a kind of economical and practical reliable floated degasser, that lean on is operator at scene
The muscle power expenditure of member's transition and uneasy full operation, have also directly influenced oil-gas exploration benefit.
