| 1 | Comprehensive geochemical identification of highly evolved marine carbonate rocks as hydrocarbon-source rocks as exemplified by the Ordos Basin显示文摘This study reversed the developing environments of hydrocarbon-source rocks in the Ordos Basin and evaluated carbonate rocks as hydrocarbon-source rocks and their distributions on account of the fact that China’s marine carbonate rocks as hydrocarbon-source rocks are character- ized by intensive thermal evolution and relatively low abundance of organic matter, by taking the Lower Paleozoic of the Ordos Basin for example and in light of the calculated enrichment coefficients of trace elements, the REE distribution patterns, the mathematical statistics analysis of elements and carbon isotopes and their three-dimensional diagrammatization in combination with the necessary organic parameters. As for the Ordos Basin, TOC=0.2% is an important boundary value. Studies have shown that in the strata where TOC is greater than 0.2%, Ba is highly enriched with positive δ 13Ccarb shifts and δ 13Corg less than ?28‰, reflecting a thigh paleo-productivity, high burial amounts of organic matter, relatively good hydrocarbon-generating potentiality and intensive REE fractionation. All these indicated that the settlement rates are low and the geological conditions are good for the preservation of organic matter, hence favoring the development of hydrocarbon-source rocks. The Klimory and Wulalik formations show certain regularities in those aspects and, therefore, they can be regarded as the potential effective hydrocarbon-source rocks. In the strata where total TOC is less than 0.2%, the contents of Ba are low, δ 13Ccarb values are mostly negative, and δ 13Corg values range from ?24‰― ?28‰, demonstrating low burial amounts of organic matter, poor potentialities of hydrocarbon gen- eration, weak REE fractionation and rapid settlement rates. These facts showed that most of the hy- drocarbon-source rocks were formed in shallow-water, high-energy oxidizing environments, thus un- favoring the development of hydrocarbon-source rocks. It is feasible to make use of the geochemical method to comprehensively assess the highly evolved marine carbonates rocks as potential hydro- carbon-source rocks and their distributions. | Tenger | 2006 | Science China Earth Sciences2006，49，4： | 20 |
| 2 | Potential petroleum sources and exploration directions around the Manjar Sag in the Tarim Basin显示文摘Since the discovery of the Tahe oilfield,it has been controversial on whether the main source rock is in the Cambrian or Middle-Upper Ordovician strata.In this paper,it is assumed that the crude oil from the Wells YM 2 and TD 2 was derived from the Middle-Upper Ordovician and Cambrian source rocks,respectively.We analyzed the biomarkers of the crude oil,asphalt-adsorbed hydrocarbon and saturated hydrocarbon in bitumen inclusions from the Lunnan and Hade areas in the North Uplift of the Tarim Basin.Results show that the ratios of tricyclic terpane C_(21)/C_(23)in the crude oil,asphalt-adsorbed hydrocarbon and saturated hydrocarbon in bitumen inclusions are less than 1.0,indicating that they might be from Upper Ordovician source rocks;the ratios of C_(28)/(C_(27)+C_(28)+C_(29))steranes in the saturated hydrocarbon from reservoir bitumen and bitumen inclusions are higher than 25,suggesting that they might come from the Cambrian source rocks,however,the ratios of C_(28)/(C_(27)+C_(28)+C_(29))steranes in oil from the North Uplift are less than 25,suggesting that they might be sourced from the Upper Ordovician source rocks.These findings demonstrate that the sources of crude oil in the Tarim Basin are complicated.The chemical composition and carbon isotopes of Ordovician reservoired oil in the Tarim Basin indicated that the crude oil in the North Uplift(including the Tahe oilfield)and Tazhong Depression was within mixture areas of crude oil from the Wells YM 2 and TD 2 as the end members of the Cambrian and Middle-Upper Ordovician sourced oils,respectively.This observation suggests that the crude oil in the Ordovician strata is a mixture of oils from the Cambrian and Ordovician source rocks,with increasing contribution from the Cambrian source rocks from the southern slope of the North Uplift to northern slope of the Central Uplift of the Tarim Basin.Considering the lithology and sedimentary facies data,the spatial distribution of the Cambrian,Middle-Lower Ordovician and Upper Ordovician source rocks was reconstructed on the basis of seismic reflection characteristics,and high-quality source rocks were revealed to be mainly located in the slope belt of the basin and were longitudinally developed over the maximum flooding surface during the progressive-regressive cycle.Affected by the transformation of the tectonic framework in the basin,the overlays of source rocks in different regions are different and the distribution of oil and gas was determined by the initial basin sedimentary structure and later reformation process.The northern slope of the Central Uplift-Shuntuo-Gucheng areas would be a recent important target for oil and gas exploration,since they have been near the slope area for a long time. | JIN ZhiJun LIU QuanYou YUN JinBiao Tenger | 2017 | Science China Earth Sciences2017，60，2： | 7 |
| 3 | Geobiological approach to evaluating marine carbonate source rocks of hydrocarbon显示文摘Evaluating the pre-Jurassic marine source rocks in China has been difficult because these rocks are generally too highor over-maturated for most traditional methods to work.As to the remaining parameter TOC (%),its lower limit for recognizing the carbonate source rocks in China has been in dispute.Nineteen Phanerozoic sections in the Middle-Upper Yangtze Platform and the Guizhou-Hunan-Guangxi Basin have been studied in search for a different approach to complementing the traditional evaluation method for these source rocks.We have applied a geobiological approach to tracing the organic carbon (OC) output and accumulation from the living stage (primary productivity) to the post-mortem deposited remains,and finally to the preserved burial organics.Four biological and geological parameters are employed to represent the OC of the three stages.A series of proxies of these parameters are discussed and integrated to establish a geobiological evaluation system independent of TOC and other traditional methods.Here we use the Guangyuan section in Sichuan as an example for the geobiological evaluation.Our results indicate that in the argillaceous rocks,the geobiological parameters show the qualified source rocks in accordance with high TOC values;but in the carbonates,the good source rocks delineated by the geobiological parameters have a wide range of TOC,from 0.03% to 1.59%,mostly<0.3%.We suggest that it is still premature to set TOC=0.3% or 0.5% as the lower limit for the pre-Jurassic carbonate source rocks in South China. | YIN HongFu XIE ShuCheng YAN JiaXin HU ChaoYong HUANG JunHua Tenger QIE WenKun QIU Xuan | 2011 | Science China Earth Sciences2011，54，8： | 7 |
| 4 | An isotope study of the accumulation mechanisms of high-sulfur gas from the Sichuan Basin, southwestern China显示文摘The mechanism of hydrogen sulfide(H_2S) generation plays a key role in the exploration and development of marine high-sulfur natural gas, of which the major targets are the composition and isotope characteristics of sulfur-containing compounds.Hydrocarbon source rocks, reservoir rocks, natural gases and water-soluble gases from Sichuan Basin have been analyzed with an online method for the content of H_2S and isotopic composition of different sulfur-containing compounds. The results of comparative analysis show that the sulfur-containing compounds in the source rocks are mainly formed by bacterial sulfate reduction(BSR), and the sulfur compounds in natural gas, water and reservoir are mainly formed by thermal sulfate reduction(TSR). Moreover, it has been shown that the isotopically reversion for methane and ethane in high sulfur content gas is caused by TSR. The sulfur isotopic composition of H_2S in natural gas is inherited from the gypsum or brine of the same or adjacent layer,indicating that the generation and accumulation of H_2S have the characteristics of either a self-generated source or a near-source. | LIU WenHui Tenger ZHANG ZhongNing LUO HouYong ZHANG DianWei WANG Jie LI LiWu GAO Bo LU LongFei ZHAO Heng | 2016 | Science China Earth Sciences2016，59，11： | 2 |
