Nutrient compositions of cultured Thalassiosira rotula and Skeletonema costatum from the Jiaozhou Bay in China

Acta Oceanologica Sinica 2008年第4期27卷 147-155页

作者： shen Zhiliang WU yulin LIU Qun YAO Yun Key Laboratory of Marine Ecology and Environmental Sciences Institute of Oceanology Chinese Academy of Sciences Qingdao 266071 China

Carbon, nitrogen, phosphorus, silicon composition of cultured two different sized phytoplankton common species of Thalazsiosira rotula and Skeletonema costatum from the Jiaozhou Bay were measured. Carbon, nitrogen, phosphorus, silicon contents in cell were obvious higher in T. rotula than in S. costatum, but the percents of nitrogen, phosphorus, sihcon contents in cell dry mass in T. rotula were lower than those in S. costatum. The dry mass concentrations of nitrogen,phosphorus, silicon in S. costatum were much higher than those in T. rotula, particularly silicon, the former was 6. 4 times of the latter, showing that S. costatum could more assimilate these elements. Especially, S. costatum had competitive dominance for assimilating silicon, which is beneficial to its becoming a major dominant species in relative short silicon of the Jiaozhou Bay. There were some differences in numerical value of nutrient ratios both laboratory-cultured phytoplankton and different sized suspended particulates （ mainly phytoplankton） in the Jiaozhou Bay, which was caused by the changes of environment. High contents of carbon, nitrogon and relative low phosporus, sil- icon, high molar ratio of nitrogen to phosphorus （far higher than Redfield value） and low ratio of silicon to phosphorus and silicon to nitrogen （far lower than Redfield values） in the two diatoms and different sized suspended particulates were consistent with those in the seawater. Relative short silicon in the seawater and phytoplankton showed that silicon was possibly affectting phytoplankton growth in the Jiaozhou Bay.

In order to discuss the geochemical characteristic of REEs （rare earth elements） and their geological application, we measured the contents of rare earth elements, trace elements and minerals of 29 Lopingian （Late Permian） mudstone samples in Panxian county, carrying out ICP-MS and XRD analysis. The results show that the amount of REEs （185.56-729.46 ×10-6） is high. The ratios of w（LREE）/w（HREE）（6.84- 13.86） and W（La）N/w（Yb）N （1.01-3.02） show clear differentiation of LREEs and HREEs. ZREE has a significantly or critically positive correlation with lithophile elements Th, Nb, Ta, Ti, Ca, Sc, Cs, Zr, Hf, Sr, Be and chaicophile element Zn, a critically negative correlation with siderophile element Fe and a slightly positive correlation with illite, illite smectite mixed layers and siderite. REEs originate mainly from terrigenous minerals, in an inorganic phase, Source rocks of our samples consist of Emeishan basalt and a small part of sedimentary rocks, as suggested by the distribution patterns of REEs and w（∑REE）- w（La）/w（Yb） diagram. Moreover, abnormal surfaces near the sequence boundaries （SB2, SB3, SB4） are related wiLth the boundaries, identified by geochemical characteristics of the REEs, such as ∑REE. w（LREE）/w（HREE）, Eu/Eu＊ and Ceanom.

Pore pressure is an important parameter in coalbed methane(CBM)exploration and development;however,the distribution pattern and mechanism for pore pressure differences in the Upper Permian CBM reservoirs are poorly understood in the western Guizhou region of South *** this study,lateral and vertical variations and mechanisms for pore pressure differences are analyzed based on 126 injection-falloff and in-situ stress well test data measured in Permian coal ***,based on the pore pressure gradient and coefficient in coal reservoirs of the western Guizhou region,five zones can be delineated laterally:the mining areas of Zhina,northem Liupanshui,northern Guizhou,northwestern Guizhou and southern ***,there are two main typical patterns:i)the pore pressure gradient(or coefficient)is nearly unchanged in different coal reservoirs,and ii)the pore pressure gradient(or coefficient)has cyclic variations in a borehole profile with multiple coal seams,which suggests the existence of a"superimposed CBM system".The mechanism analysis indicates that coal permeability,thermal evolution stage and hydrocarbon generation contribute little to pore pressure differences in coal reservoirs in the western Guizhou *** present-day in-situ stress field,basement structure and tectonic activity may be the dominant factors affecting lateral pore pressure *** sealing capacity of caprocks and the present-day in-situ stress field are significant para-meters causing vertical pore pressure differences in coal *** results are expected to provide new geological references for CBM exploration and develop-ment in the western Guizhou region.

鄂尔多斯盆地东缘煤层气、致密砂岩气及页岩气"三气"共存,该区上古生界煤系储层垂向上存在着多个独立的含气系统,目前对该类煤系叠置含气系统发育的沉积控制机理尚缺乏系统深入的研究。为此,基于该区临兴区块上石炭统本溪组—下二叠统山西组钻井岩心观察及钻井、测井资料分析结果,探讨了上述问题。研究结果表明:(1)该区煤系叠置含气系统的发育受控于层序格架内具低孔隙度、低渗透率和高突破压力的含菱铁矿层(关键层)的空间展布;(2)关键层的发育受控于区域海侵事件层的空间分布,主要发育于最大海泛面附近并构成叠置含气系统隔水阻气的边界;(3)二级层序内最大海泛面附近广泛发育的关键层,构成了全区稳定发育的含气系统边界,三级层序最大海泛面附近发育的关键层常因后期(水下)分流河道冲刷切割而保存不全,促使相邻层序的煤系储层组合成统一的含气系统,为该区煤层气与致密砂岩气的共采创造了有利的地质条件。

叠置含气系统及其兼容性是煤系多类型非常规天然气合采可行性判识基础。基于临兴区块地层压力、天然气地球化学及生产数据解译,划分了叠置独立含气系统,探讨了含气系统间兼容性。基于地层压力梯度差异认为目标层段至少存在7套独立含气系统;基于产层的天然气甲烷同位素差异,认为太2段、山2~山1段、盒8~盒6段、盒3段等4套层系互不连通;基于天然气生产曲线差异,识别出山西组与石盒子组为2套独立含气系统。综合将研究区自上而下划分为千1~千4段、千5段、盒1~4段、盒5~8段、山1~太1段、太1~太2、本1段及本2段等独立含气系统。提取了地层压力梯度、气层厚度、渗透率及可动水量等影响合采兼容性关键因素,采用最优分割分类方法,指出研究区含气系统兼容性最佳分类数为5~6类,千5段、盒1~4段、盒5~8段等3套叠置含气系统合采兼容性较好。
