Although several studies have reported on the propagation of the Sagittaria sagittifolia to date, none of these methods have efficiently achieved the mass production of these plants. The present study aimed to investigate the propagation and growth of S. sagittifolia using a temporary immersion bioreactor system （TIBS） compared with conventional semi-solid and liquid culture. The effect of different immersion frequencies and immersion times together with supplementation of various plant growth regulators to the Murashige and Skoog （MS） medium was evaluated on shoot proliferation and plant growth. The results showed that the higher immersion frequency （every 6 h） and shorter immersion time （3 min and 10 rain） in medium containing 4 mg/L BA and 0.1 mg/L NAA produced the highest multiplication rate （23）, which are significantly higher than conventional semi-solid （3.6） and liquid （4.5） method, and the best plant growth parameter. While, the lower immersion frequency and longer immersion time （30 rain every 12 h and 60 min every 24 h） induced vitrification and pollution rate in shoot tips 16.6% and 19%, 42% and 37%, respectively. There is distinct decrease in pollution rate （8.3%） in TIBS （10 min every 6 h） compared with the conventional semi-solid and liquid cultures. Medium containing 4 mg/L BA and 0.5 mg/L NAA using 10 min immersion every 6 h showed satisfaction at the rooting stage, with high shoot proliferation rate （21.6）, 100% rooting and 94% plant survival. Therefore, applying TIBS in S. sagittifolia is an efficient method for scaling up the production of plantlets with high quality seedlings.

Chinese Journal Of Geochemistry 2013年第1期32卷 78-84页

作者： Xie Guanbao Qin Liming Zhang zhihuan Li Wenhao School of Geosciences China University of Petroleum Sinopec Research Institute of Petroleum Engineering State Key Laboratory for Petroleum Resources and Prospecting China University of Petroleum

In the Yongjin oilfield of southern Junggar Basin, many wells have been drilled to produce industrial oils. Based on the analysis of fluid inclusions in the reservoirs, in combination with the geological and thermal evolution, the charge history in this area has been studied. The results indicate that the Jurassic Formation and Cretaceous Formation reservoirs contain abundant oil and gas inclusions, and four types of fluid inclusions have been distinguished. According to the homogenization temperatures of the fluid inclusions, the hydrocarbons charged the Cretaceous Formation for two periods, one ranges from the Late Cretaceous period to the Eogene period, and the other ranges from the Neocene period to the present. The oil filling history is correlated with the oil source correlation analysis, which is controlled by the movement of the Che-mo plaeo uplift. Overall, oil accumulation is characterized by the superposition of two sets of source rocks for two stages in the Shawan depression.

Petroleum Science 2007年第4期4卷 34-43页

作者： Li Wei Zhang zhihuan Yang Yongcai Meng Xianlong International Petroleum Exploration and Production Company Sinopec Beoing 100083 China Key Laboratory of Hydrocarbon Accumulation Ministry of Education China University of Petroleum Beijing 102249 China West China Branch of lnstititute of Exploration and Development Sinopec Urumqi Xinjiang 830011 China

Through oil-oil and oil-source correlation and combined with the comprehensive study of hydrocarbon generation and accumulation history, the oil sources of typical reservoirs of different geologic periods in the hinterland of the Junggar basin are revealed. It is concluded that the crude oils in the study area can be classified into four types： The oil in the area of well Zhuang-1 and well Sha-1 belongs to type-I, which was generated from Cretaceous to Paleogene （K-E） and its source rocks are distributed in the Fengcheng formation of the Permian in the western depression to the well Pen-1. The oil in the area of well Yong-6 （K1 tg） belongs to type-Ⅱ, which was generated from Cretaceous to Paleogene and its source rocks are distributed in the Wuerhe formation of the Permian in the Changji depression. The oil in the area of well Yong-6 （J2x） belongs to type-III, which was generated at the end of the Paleogene and its source rocks are distributed in the coal measures of the Jurassic in the Changji depression. The oil of well Zheng-1 and well Yong-1 belongs to type-IV, which was generated in the Paleogene, and its source rocks are distributed in the Wuerhe formation of the Lower Permian and coal measures of the Jurassic. It is indicated that the hydrocarbon accumulation history in the study area was controlled by the tectonic evolution history of the Che-mo palaeohigh and the hydrocarbon generation history of well Pen-1 in the western depression and Changji depression.

In the hinterland of the Junggar Basin, there are multiple depressions with multiple sets of source rocks. Therefore, the conditions of hydrocarbon sources are complex, and the geochemical characteristics and sources of hydrocarbon vary in different structural belts. The evolution of the Che- mo palaeohigh affected the formation of hydrocarbon source kitchens and hydrocarbon migration. We studied the combination and superimposition of hydrocarbon source kitchens, using as an example the hinterland of the Junggar Basin （including the Yongjin, Zhengshacun, moxizhuang and Luliang uplift areas）. The study was based on geochemical analyses of crude oil and fluid inclusions, and the histories of tectonic evolution and hydrocarbon generation. The results indicated that before the Paleogene there were two hydrocarbon-generating depressions： the Western Well Penl depression and the Changji depression on the south and north sides of the Che-mo palaeohigh, respectively. The Permian source kitchen had been generating hydrocarbon continuously since Triassic and reached high maturity stage in the Cretaceous period. After Paleogene, the adjustment of the Che-mo palaeohigh led to the subsidence of the Changji depression and the Jurassic source rocks reached mature stage and became the main source kitchens. However, the Jurassic source rocks in the Western Well Penl depression were still in a low maturity stage and did not generate oil because of the adjustment of tectonic movements. As a result, in the central and southern parts of the Junggar Basin, Jurassic source rocks generated oil, but in the Luliang uplift, the crude oil was from the Permian source rocks in the Western Well Penl depression and the Jurassic source rocks did not contribute. The crude oil in the central Zhengshacun-moxizhuang belt was from the Permian source rocks in two depressions, and partially from the Jurassic source rocks. The crude oil in the Luliang uplift was from the source rocks of the lower Permian F

通过对准噶尔盆地中部Ш区块原油或油砂抽提物的饱和烃气相色谱—质谱分析,研究了原油或油砂抽提物中25-降藿烷的分布规律。结果表明,不同井区或同一口井不同深度(层位)的原油25-降藿烷的相对含量存在比较明显的差别,表明其所遭受的生物降解程度有所差异,沿构造带从南到北,同一油层中原油的生物降解程度增强,比如位于构造北部(构造部位相对较高)的永1井、永3井侏罗系原油25-降藿烷丰度较高,表明生物降解比较明显,而位于南部(构造低部位)的永6井白垩系和侏罗系油层中的原油均无明显的生物降解现象;同一口井随深度增大生物降解作用将弱,如永2井浅部白垩系油层的原油降解较严重,而深部西山窑组的原油降解作用则不明显。根据原油生物降解的特征,结合车-莫古隆起调整对研究区油气成藏的影响,讨论了原油生物降解差异分布的成因机制。

依据生物标志物的分布和组成特征,准噶尔盆地腹部侏罗系三工河组的原油可以分为两类,庄1井和沙1井原油属于第一类,源于下二叠统风城组;南部征沙村地区征1井原油为第二类,源于中二叠统下乌尔禾组,也有侏罗系的贡献。根据流体包裹体均一化温度分布,结合生排烃史与构造配置关系研究,认为征1井三工河组油藏主要成藏期是古近纪以来,油气来自于昌吉凹陷的下乌尔禾组和侏罗系烃源岩;而庄1井和沙1井三工河组油藏具有多源多期油气注入,早白垩世末至古近纪,油气来自于北部盆1井西凹陷风城组,古近纪构造调整以来,混入了来源于昌吉凹陷的油气。各口井原油含氮化合物的分布特征,证实了研究区侏罗系原油近期是从征1井向北运移的。
