The invention aims to overcome the detects of the prior art that only a rough accumulation moment scope or the earliest accumulation time can be qualitatively or semi-quantitatively given but a specific accumulation year cannot be confirmed, and provides an accurate, convenient, practical and easily-popularized analysis process for confirming the accumulation key moment of oil gas. The analysis process comprises the following steps: performing microscopic fluorescence spectrum measurement on a single hydrocarbon inclusion; analyzing the organic components in the single hydrocarbon inclusion in the diagenetic mineral and comparing with the organic components of crude oil in present oil pool; reconstructing the whole accumulation process; and determining the accumulation key moment of oil gas.
Description
Technical field:
The present invention relates in a kind of reservoir exploration process determine the Hydrocarbon Formation Reservoirs analytical technology at crucial moment, be particularly related to single oil gas inclusion in reservoir " microcosmic oil " organic principle, carry out the sibship contrast with oil reservoir Crude Oil now " macroscopic view oil " composition, and in conjunction with hydrocarbon fluid inclusion homogenization temperature, the whole one-tenth of reconstruct is hidden process, and then determines the method that effective one-tenth is hidden the phase.
Background technology:
Fluid inclusion in sedimentogeneous rock is by cementing matter or authigenic mineral, to be caught in Diagn, be wrapped in the diagenesis fluid in defect, pothole or the crack of mineral lattice, its in store original diagenesis fluid, and with the external world, mass exchange does not occur in very long geochron, so it has recorded various physics, the chemical information that becomes the ore deposit medium when host minerals forms, and the migration that becomes the ore deposit fluid is had to important Detectable effects.
The Fluid-inclusion analysis technology is widely used in the oil geology field in recent years, aspect becoming to hide chronology and becoming to hide history research, the application of fluid inclusion mainly contains three aspects: the one, in the formation epoch of hydrocarbon inclusion, represented the filled phase of oil-gas migration time; The 2nd, the homogenization temperature of hydrocarbon fluid inclusion, recorded the palaeogeothermal of reservoir when oil-gas migration fills, depth of burial in the time of can determining that by the recovery of thermal history and reservoir buried history the inclusion inclusion forms, one-tenth generation Tibetan New Year that its corresponding Stratigraphic Time is hydrocarbon-bearing pool; The 3rd, the composition of hydrocarbon inclusion, geochemical characteristics and phase characteristics while can reaction oil gas filling.The composition Study of hydrocarbon inclusion and corresponding inclusion form phase time, homogenization temperature combines and compare with the composition of hydrocarbon-bearing pool, can make judgement more accurately to one-tenth generation Tibetan New Year of concrete hydrocarbon-bearing pool.Can study hydro carbons Kerogen Characteristics and degree of ripeness by the test to the hydrocarbons of fluid inclusions component, and then source and the migratory direction direction of understanding oil gas, and use features of fluid inclusion research oil filling history to prove effective way and the means of Study on hydrocarbon reservoir formation process.
Traditional bulk fluid inclutson analysis in the past, that can only estimate oil gas may become generation Tibetan New Year, but can not accurately determine one-tenth generation Tibetan New Year of hydrocarbon-bearing pool.And the bulk fluid inclutson analysis exists secondary fluid inclusion and other interference of fluid inclusions from generation to generation, simultaneously because need to open fluid inclusion, likely with external substance generation mass exchange and chemical reaction, in leaching process, cause inclusion to pollute.For all puzzlements of bulk fluid inclutson research, need constantly to attempt dwindling observation scope with various new analytical technologies, if can determine single fluid inclusion composition, just can one-tenth Tibetan New Year of concrete hydrocarbon-bearing pool be judged for making more accurately.The development of the investigative technique of single inclusion, make the study on inclusions microcell, the new method of current single fluid inclusion composition Study comprises the method for the single fluid inclusion composition of destructive analysis, and original position nondestructive analysis method, its situ nondestructive analysis method is owing to not needing to open inclusion, reduce the uncertainty in the test process, become the focus of research.
The single fluid inclusion analysis technology at the present invention proposes definite Hydrocarbon Formation Reservoirs crucial moment, just be based on inclusion original position nondestructive analysis method, for single hydrocarbon inclusion, can't harm photometric measurement, obtains the important composition finger print information of inclusion.And form by analyzing single hydrocarbon inclusion organic principle in the diagenesis mineral, forming and contrasted with the organic principle of oil reservoir Crude Oil now, the whole one-tenth of reconstruct is hidden process, and then the method at the crucial moment of definite Hydrocarbon Formation Reservoirs, has no granted patent at home and abroad.
Summary of the invention:
The object of the invention is to overcome the deficiency of prior art, the analytical technology at a kind of accurate, easy, practical and Hydrocarbon Formation Reservoirs crucial moment of being easy to promote is provided.
Method of the present invention is to change oil inclusions molecule geochemical composition in traditional analysis reservoir diagenetic mineral, in conjunction with the inclusion homogenization temperature, estimates the method that the Hydrocarbon Formation Reservoirs phase is inferior.To, the same period, inferior inclusion was not described classification to new method, and inferior inclusion of each phase be can't harm to photometric measurement, composition and degree of ripeness to single inclusion are analyzed, with crude oil (tar sands extracting crude oil) fluorescence, contrasted, set up the contrast fingerprint base, carry out the contrast of dissimilar inclusion " microcosmic oil " and crude oil " macroscopic view oil ", determine the sibship of Reservoir Crude Oil and inclusion given period time " crude oil "; Meanwhile, each inclusion is carried out to homogenization temperature mensuration, obtain the homogenization temperature of inclusion homogenization temperature dissimilar and not same period time and corresponding salt solution inclusion, and obtain the homogenization temperature with the single inclusion of " macroscopic view oil " coupling, the key temperatures that oil reservoir injects; By the basin modelling method, temperature burial history curve while setting up meticulous individual well, and ask for the oil gas injection length according to homogenization temperature (key temperatures) on curve, namely " crucial moment " of reservoir formation.
The accompanying drawing explanation:
Determine the Hydrocarbon Formation Reservoirs single fluid inclusion analysis techniqueflow chart at crucial moment.
Embodiment:
One, inclusion petrological study, in the luminous situation of fluorescence microscopy Microscopic observation inclusion, to not, the same period, inferior inclusion was described classification, and inferior inclusion of each phase be can't harm to photometric measurement, set up the fingerprint base of single inclusion.Record experimental result, composition and the degree of ripeness of single inclusion are analyzed.
Two, each inclusion is carried out to homogenization temperature mensuration, obtain the homogenization temperature of inclusion homogenization temperature dissimilar and not same period time and corresponding salt solution inclusion;
Three, crude oil (tar sands extracting crude oil) is carried out to geochemistry and divide, comprise fluorescence analysis, set up fingerprint base.In addition, crude oil is carried out to fractional analysis routinely.
