Description
The utility model belongs to fluid sample and quantitatively outgases and use analytical instrument, be particularly related to be applied to oil and gas exploration gas survey record and in to the quantitative degasifier of vacuum distillation of drilling fluid (mud) degassing, be gas detection logging stratographic analysis sampling gas.Also can be used for the quantitatively full degassing of other liquid (comprising the very liquid of thickness).Be particularly useful for the degassing of transformer oil, be the stratographic analysis sampling gas of transformer oil.
Existing prior art: French heat production VMS degasifier (see figure 1).China's French thermovacuum mud distillation degasifier of introduction (VMS) in the gas of oil and gas exploration is surveyed and worked outgases in order to identification entirely to drilling fluid (mud) and estimates hydrocarbon zone, and nearly so far 30 years, still widely application in oil-gas exploration at present.Theoretically, the VMS degassing is analyzed two of modern mud logging interpretation work is required greatly: (make the mud logging data carry out scene, early stage, quick identification and evaluation to hydrocarbon zone; Can carry out contrasting between interlayer, well) important meaning arranged, show and offer the necessary following important parameter of geologic interpretation: the rock gas component, the continuous degassing device is proofreaied and correct drilling fluid (mud) gassiness degree of saturation, ground air content (SPI), formation gas bearing amount (CGS).But China decades facts have proved that still there is following major issue in VMS, the solution of these problems will be given VMS with new vitality, and comes out with new instrument.
It is as follows that the subject matter of VMS is concluded analysis:
1, the serious distortion of the drilling fluid of Cai Jiing (mud) sample:
At present, outlet drilling fluid (mud) sample generally is to gather at drilling fluid (mud) delivery channel mouth, and when taking the drilling fluid (mud) that returns on storage gas and the landwaste before this and flowing to the parallel port liquid level, free in a large number shape rock gas escapes in the air, causes institute's sample thief distortion.
2, drilling fluid (mud) sample amount of gas evolved distortion.
Because the shortcoming of VMS structural design has caused and has adopted the distortion of drilling fluid (mud) sample amount of gas evolved:
(1) gas of deviating from is collected incomplete
The gas volume that gauge line (G5) is collected is a part of deviating from gas only, and the gas in (managing in space, the vacuum meter on pipeline, the bottle P2 mud liquid level) between valve A and the valve B can't be collected, and this portion gas may account for 1/2 of gas.
(2) entrained air pipe H, air entrained gas in operating process of valve A through hole inner volume, the air among the pipe U is all sneaked into the gas sample.
(3) it is few to sneak in the water vapour G6 salt solution, is difficult to absorb a large amount of water vapours, makes water vapour enter G6 and G5.
3, gas composition, the concentration distortion of drilling fluid (mud) sample:
(1) a large amount of free gases (light component is main) escape into atmosphere.
(2) G5 absorption heavy hydrocarbon under the normal temperature.
(3) entrained air in the degasification process.
4, the VMS degassing, analysis result vary with each individual.
The degassing, the analysis result artifical influence factor is too many, and manual result makes the degassing, analysis result make us varying with each individual uncannily.
5, inefficiency:
A drilling fluid (mud) sample was finished approximately time-consuming 30 minutes to the degassing by preliminary work, and incompatibility gas is surveyed and about the requirement of " on-the-spot, quick identification and estimate hydrocarbon zone ".
6, bottle P2 only is heated the bottom, and the efficiency of heating surface is low, when making sample continuously, scalds one's hand when taking off the bottle P2 that has taken off gas.
7, bottle P2 is a glassware, and is frangible, dangerous; A little less than the magnetic agitation power, stirring rod is easily forgotten and is put into a bottle P2.
Though above-mentioned VMS is badly in need of being upgraded because of many disadvantages in theory to the identification of hydrocarbon zone and estimate significantly, needs new, the more advanced degasifier of exploitation to replace it.
The objective of the invention is:
The invention provides the quantitative degasifier of a kind of semi-automatic vacuum distillation, overcome above-mentioned prior art major defect, adopt the metal degassing tank, quantitatively take drilling fluid (mud) sample, directly heat in the degassing tank and motor machine stirring drilling fluid, heated constant temperature temperature and mixing time can be set and control automatically, the drilling fluid degassing rate is fast, degasifying effect is good, repeatability and comparability are good, can accomplish that the full degassing collects entirely, the sample gas that is obtained is component entirely, concentration is constant sends into partition gas chromatograph quantity tube (the also mode of available VMS automatically, extract sample gas with syringe), degassing overall process realizes semi-automation high efficiency, in the hope of replacing VMS, for the work of oil and gas exploration gas detection logging obtains data more accurately.As be used for the degassing of other liquid, also can be convenient to the on-the-spot correct appropriate judgement of making in early days, fast.
