盐浓度对石油菌生长影响的热动力学研究

用 2 2 77热活性检测系统测定了一株石油菌在不同NaCl浓度下生长的功率—时间曲线 .根据广义Logistic方程 ,建立了石油菌生长的功率—时间曲线方程 :ln[aPk/P(t) -1] =ln[(aK -N0 ) /N0 ] -akt,用四点法求得了PK.得到了该石油菌生长的最适NaCl浓度为 32 1g·L 1 .     

Multi-origin alkanes related to CO2-rich, mantle-derived fluid in Dongying Sag, Bohai Bay Basin

With the newly obtained carbon isotope data for the natural gas, a pilot study of multiple-sourced alkanes related to the mantled-derived fluid is presented. The carbon isotope values of alkanes in the Dongying Sag possess thefea tures indicating a general organic origin. However, there are two sub-populations in the isotopic data set, which reflect two specific types of origins. In gene ral, the sub-population with high δ13CCH4 values is related to the CO2-rich, mantle-derived fluid, and it is distributed in the belts where mantle-derived fluid flow and basic volcanic activities have occurred. Geological and geochemical studies demonstrate that this variation of methane carbon isotope values in the Dongying Sag is unrelated with the basin bury and thermal histories, types of source rocks, and reactions between basin fluid and rocks. Mixing of mantle-derived fluid and organic sourced hydrocarbons is probably the cause for the variation .

分形理论在地震道油气检测中的应用

认为地震道是混沌的时间序列，混沌运动的轨迹在相空间中的某个区域内经无穷次的折迭，扭曲和拉伸，构成一个有无穷层次嵌套的自相似结构－奇异吸引子。对实际的地震道信号所构成的联井反射点剖面数据进行处理，运用重建相空间法（即Ｇｒａｓｓｂｅｒｇｅｒ－Ｐｒｏｃａｃｃｉａ算法），计算出各道的关联维数，并与实际的钻井资料进行比较。对关联维数与钻井结果的关系进行了解释。用实际参照井检验，结果十分吻合。     

Structural characteristics and petroliferous features of Tarim Basin

Using the modern tectonic geology theories andmethods such as the plate tectonic analysis, the paleo-struc-ture analysis, the structural-Iithofacies analysis, and the faultrelated fold and petroleum system, and combining with theseismic data, well drilling data and the circumferential fieldgeology, study on the structural characteristics and petro-leum prospect in the Tarim Basin has been carried out. Re-sults show that the Tarim Basin is a large superimpositionand combination basin with continental crustal basement,composed of a Paleozoic craton and Meso-Cenozoic forelandbasins. The characteristics of the basin are: the kernel partof the basin is the marine facies Paleozoic craton, superim-posed 4 continental facies foreland basins. Though the scaleof the paleozoic craton of the Tarim Basin is relatively small,the structure is steady. The petroleum prospect of the Paleo-zoic craton is: multiphase pool-generation and accumulationcontrolled by ancient uplift. The Meso-Cenozoic forelandbasins in the Tarim Basin, which are distributed on the era-tonic circumference and are a long-term subsidence, turnedinto rejuvenated foreland basins after the Meso-Cenozoicperiod. The petroleum prospects are: coal-bed generatinghydrocarbon, abundant natural gas, pool-generation in laterand recent periods, the oil and gas distribution controlled bythe foreland thrust belt. The structural characteristics ofTarim provide it with a superimposition and combinationpetroleum system of multiple resources, multiple reservoirsand multiphase pool-generation. The oil and gas explorationprospect covers two large fields: the Paleozoic craton and theMeso-Cenozoic foreland thrust belt.

多变量非线性组合模型在石油消费预测中的应用

我国石油消费需求除了受经济增长、技术进步、能源结构、产业结构调整等几种常见因素的影响外,还有石油价格、国家能源消费政策和政府提出的循环经济,大力推广节油措施和开发节油项目等因素影响石油消费上升的速度[1].为了提高预测的准确性和稳定性,本文构建了多变量非线性加权     

南海深水海域近代沉积物中饱和烃的地球化学特征及其来源

对南海深水海域(水深>130 m)的6个表层沉积物样中的饱和烃进行了测试,正构烷烃nC21-/nC21 一般小于0.6,意味着陆源高等植物生物蜡来源的正构烷烃占优势,CPI值比正常海洋沉积物明显偏低.较高含量的不溶复杂混合物(UCM)、iC16、iC18、植烷、姥鲛烷被检测到,地质构型藿烷、甾烷在甾萜类化合物中为优势组分,萜甾烷参数显示了较为成熟的信息.饱和烃的多种地球化学参数不同程度的显示了石油源有机质混入的迹象,混入的石油源烃可能主要来自人类活动和海底天然油苗.
