A discussion on the upper limit of maturity for gas generation by marine kerogens and the utmost of gas generative potential:Taking the study on the Tarim Basin as an example

Science Bulletin 2007年第S1期 125-132页

作者： CHEN JianPing1,2, ZHAO WenZhi1, xiao ZhongYao3. zhang ShuiChang1,2, DENG ChunPing1,2, sun {3.4 & WANG ZhaoMing3.1 Research institute of Petroleum Exploration & Development, Petrochina, Beijing 100083. china 2 key Lab of Petroleum Geochemistry, CNPC, Beijing 100083. china 3.Research institute of Petroleum Exploration & Development, Tarim Oilfield Company, Petrochina, Korla 841000, china 4 state key Lab of organic Geochemistry, guangzhou institute of Geochemistry, chinese academy of sciences, guangzhou 51064., china

The experimental data yielded by Rock-Eval pyrolysis, kerogen atomic H/C, Py-GC and gold-tube sealing thermal simulation on the marine Cambrian-Ordovician source rock from the Tarim Basin revealed that the upper limit of maturity for natural gas generation or the "deadline of gas generation" for marine types I and II kerogens is equal to 3.0% of vitrinite reflectance (Ro); while the "deadline of gas generation" for type III kerogens typically like coals is as high as 10% Ro. Thus, different organic matter has obviously different utmost maturities for gas generation. The mass-balance calculation by kerogen elements showed that when Ro>1.5%, the utmost amount of gas generation for the marine type II kerogen is less than 185 m3.t TOC, accounting for less than 3.% of its total hydrocarbon generative potential; when Ro>2.0%, it becomes 110 m3.t TOC, less than 2.% of the total hydrocarbon generative potential. The amount of the gas generative potential obtained by Rock-Eval is only around one tenth of the calculated value by the mass balance of kerogen elements at the same thermal evolutionary stage, while those by Py-GC and gold-tube sealing simulation are intervenient between the above two. The utmost of gas generative potential at the over 1.3. Ro stage is around 60―90 m3.t TOC, therefore, the amount of gas generation obtained by Rock-Eval is the minimum of gas generative potential, while that by the mass-balance calculation of kerogen elements is the maximum that the actual amount of gas generation should not exceed.

通过活性炭对不同分子结构的有机物--阳离子嫩黄和苯酚、不同水体环境中苯酚的吸附,以及对水源水中挥发性有机物和可提取有机物的吸附规律研究结果表明,活性炭对水体中有机物的吸附量不仅与有机物的分子结构有关,而且与水体中有机物种类的多寡有关,水体中的各种有机物在活性炭上存在竞争吸附,对于挥发性有机物,随分子量的增大,其在活性炭上的吸附量越大;而对可提取有机物,随分子量的增大,其吸附量反而减小。

由于土壤的非均质性,同一样品的多个光谱测试点位置之间以及同一土壤发生层的多个样品之间,均存在着不同程度的光谱差异,进而导致光谱估测的土壤属性具有误差。截至目前,还没有揭示这种误差的研究报道。在我国南方典型丘陵区林地的小区内,用环刀重复2.采集了80个土壤剖面发生层和3.个土壤表层的样品,再分别用原位光谱法和传统实验室方法测定土壤有机质含量,从而分析因光谱测试点和样品采集位置不同导致的土壤有机质含量估测误差。结果表明:每个样品在共计18个测试点位置上的光谱差异为0.12.~8.13.,均值为1.55°;在共计2.重复采样位置之间的光谱差异为0.18°~3.65°,均值为0.88°。因测试点和采样位置不同导致的土壤有机质估测误差用标准偏差表示,分别为0.92.14.66和0.005 7~11.46 g·kg^-1,占实测有机质的3.8%~42.%和0.017%~92.。同时,这两种误差会随着实测有机质值含量的增大而增加。并且,测试点位置不同导致的误差比偏最小二乘回归模型所导致的误差还要大。研究认为,今后的研究中需注意测试点和采样位置不同引起的误差,尤其是有机质含量较高的土壤。

棕色碳是一类重要的吸光性有机气溶胶,对全球辐射强迫有重要贡献。其化学成分和形成机制是地球科学研究的前沿和难点。模拟实验结果表明,羰基化合物和还原性氮的液相反应产物在近紫外波段具有较强的吸光性,且化学成分复杂,难以分离和鉴定。本研究回顾了基于实验室羰基化合物和还原性氮的反应速率、反应机制,以及反应产物中吸光组分的化学成分和光学性质;总结了反应条件(反应物种类、浓度、溶液酸度、温度和相对湿度)对反应速率和吸光组分形成的影响;并指出了外场观测和模型研究对这一贡献认识的不足。
