Description
Technical field
The present invention relates to oil exploration technology field, 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 constituted 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 is exactly that will be free on drilling fluid
In gas by stirring separation 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, by drilling fluid broken blade, collection chamber, the outlet of sample gas etc.
Composition, is a kind of degasser simple in construction, cheap.The power breaking drilling well that it is given birth to using drilling fluid gravity flow movable property
Liquid, makes gas therein escape automatically.Because it can only crush drilling fluid top layer, therefore degassing efficiency is low, and only 5% or so.Utilize such
Degasser can only gather the free gas in drilling fluid.Such current degasser is eliminated substantially.
（2）Quantitative degasser
Quantitative degasser is a kind of by carrying out a kind of engine degasser of thorough degasser to a certain amount of drilling fluid, but is belonged to
Discontinuous.
（3）Thermal vacuum distills degasser
Thermal vacuum distillation degasser is commonly called as taking off entirely, is a kind of dress that backlash sampling degassing is carried out using heating, vacuum distillation mode
Put, degasser efficiency high, it is general up to more than 95%, but belong 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, made therein
Gas is escaped.This kind of degasser degassing efficiency is general 20% or so, but deep influenceed by drilling liquid height change and can not
Realize the continuous degassing in just sincere justice.
Above-mentioned four kinds of degassers are protruded and common lacked as use for many years in oil-gas exploration gradually exposes it
Point, i.e., 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 in degassing interior to be crushed, gas escape is come out supplied gas detection use.But, for many years
Application attestation, degasser itself changes by drilling liquid and influenceed deeply, frequently causes liquid level to come to nothing, liquid level just connects after coming to nothing
Air has been touched, continuous degassing has been interrupted.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, drilling fluid is collected 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, above-mentioned all kinds of degasser exists following
The subject matter of several aspects：
（1）Degassing efficiency is low, it is impossible to 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 frequent, and manually operated degasser height is unable to reach promptness at all；
（5）Stirring produced by the stirring theory of stirring rod can not exclude high density and high viscosity drilling fluid is difficult；
（6）The erection of degasser installs complicated, and space-consuming is big, influences other operations, and be unfavorable for occupational health protection；
（7）The automatically and successively property of degassing can not be realized, oil-gas exploration benefit is influenceed.
In oil-gas exploration, scene is also without a kind of economical and practical reliable floated degasser, and that lean on is operator
The muscle power expenditure and uneasy full operation of member's transition, have also directly influenced oil-gas exploration benefit.
The content of the invention
The technical assignment of the present invention is that there is provided a kind of floated degasser of oil exploration for solution the deficiencies in the prior art.
