Description
Technical field
The invention relates to the lighter hydrocarbons collection technique of lighter hydrocarbons content and isotope value in the applied geochemistry methods analyst rock of petroleum geology exploration field, relate in particular to the gathering-device of light hydrocarbon component in a kind of rock sample with cryogenic seal crushing function.
Background technology
Lighter hydrocarbons refer to give birth to, carbon number is less than 15 hydrocarbon compound in oil-saturated reservoir rock or the petroleum gas, and carbon number is more than or equal to the corresponding heavy hydrocarbon that is called as of 15 hydrocarbon compound.Lighter hydrocarbons are the important component part of hydrocarbon component in rock gas, oil and the rock sample normally.For lighter hydrocarbons contained in rock gas and the oil, utilize the method for gas chromatography can be with they compartment analysises well.But in the at present various analysis experiments for life, the contained hydrocarbon compound of oil-saturated reservoir rock, often be subject to the restriction of experimental analysis technology, most lighter hydrocarbons in the sample pre-treatments stage all by the people for losing, be difficult to quantitative test and estimate its accurate content in rock sample, and then missed many Useful Informations.As everyone knows, in the evaluation of hydrocarbon resources amount, need accurately to know the content of the hydrocarbon component of gamut in the rock sample, just can make resource evaluation more can reflect actual conditions, and the content of lighter hydrocarbons and running parameter can be used to estimate abundance, type and the degree of ripeness of oil source rock organic matter in the rock sample, therefore, the light hydrocarbon component in Correct Analysis and the study of rocks sample is very necessary.
Be used at present measuring rock light hydrocarbon compound ripe be the pyrolysis gas chromatography (Pyro-GC) technology.This analytical technology is that the rock sample that will pulverize is placed in the special pyrolysis annex on the gas chromatograph injection port, rock sample is heated to 200-300 ℃, the lighter hydrocarbons compound component that is included in the rock sample is evaporated by heat, by cooling it is captured by chromatographic column after entering injection port with carrier gas, then carry out stratographic analysis by temperature programme.For example, Chinese patent 02113247.X adopts the disseminated organic matter in the intensification heat hydrocarbon source rock, make the hydrocarbon component desorption after being heated to uniform temperature that is adsorbed on the organic matter in the rock become organic hydrocarbon gas, with inorganic gas as: nitrogen, hydrogen, helium etc. are done carrier gas it are written in the collection tube of a low-temperature space, make its cohesion become liquid hydrocarbon and then are used for other analysis.The advantage of this technology is easy and simple to handle, and analytical cycle is shorter; Shortcoming is to cause the volatilization of part lighter hydrocarbons in broken sample process, and the diffusion conditions of lighter hydrocarbons is inconsistent in heating process, causes collected light ends fractionation incomplete, and the as a result repeatability of quantitative test is relatively poor.
Chinese patent 02160133.X employing is hermetically sealed, the low boiling point solvent cold-draw is put forward technology, carries out the sealing extracting of rock sample under the normal temperature, can prepare the various hydrocarbons that comprise light ends fractionation, thereby can carry out the analytical test of multiple analysis project.The core technology of this rock sealing hydrocarbon extraction instrument is that rock is in the following pulverizing of hermetically sealed condition limit extracting.Lower in working order, the paddle wheel High Rotation Speed produces larger centrifugal force, makes granular rock sample in the cylindrical shell with solvent strenuous exercise upwards, and firmly encircle with blade, the cylinder inboard wall of High Rotation Speed and top cover of cylinder body produces strong collision, thereby granular rock sample is pulverized.Simultaneously, in the process of High Rotation Speed, solvent will be ground in the rock sample of powder the hydrocarbons drawer out.The weak point of this instrument is the crushing effect of hard rock not good enough, such as limestone, tight sand etc.In addition, because the part in the closed barrel is more, residue is difficult for cleaning up.
Deficiency for above-mentioned technology, Chinese patent 200310103219.6 does up and down with hardness much larger than the steel ball of any rock hardness that straight reciprocating motion smashes rock sample in the O-ring barrel, the hydrocarbons of the Powdered rock sample adsorption that in this process, is crashed to pieces simultaneously also under the effect of motion solvent by solvent extraction.This technology to smash effect better, particle diameter can reach more than 90% greater than the powder rock sample more than 100 orders.And since the cylindrical vessel integral sealing, therefore also free of losses of light hydrocarbon material in the rock in sample making course.After each sample preparation finishes in addition, clean to the residue in the sealed cylindrical container also easy cleaning.But above-mentioned two kinds of devices all need be used the organic solvent freon-11 that environment is had obvious contamination in leaching process, and this reagent must pass through purifying before use, and the purified product of gained is answered the inclusion-free chromatographic peak through gas chromatographic analysis.In addition, in the situation that lighter hydrocarbons content is less, the product of above-mentioned two kinds of extraction elements also needs the liquid-concentrating instrument in Chinese patent 200510056779.X to process and obtains lighter hydrocarbons extraction concentrate.Although this liquid-concentrating instrument is airtight container and the generation negative pressure of can bleeding the solvent of evaporation is taken out, because what adopt is the water-cooled system, higher environment temperature will cause carbon number less than 6 light hydrocarbon component by scattering and disappearing in various degree, affect accuracy and the repeatability of quantitative analysis results.
Thus, the inventor relies on experience and the practice of being engaged in for many years relevant industries, proposes the gathering-device of light hydrocarbon component in a kind of rock sample, to overcome the defective of prior art.
